1. Project Core Positioning and Product Definition

　　Core Objectives of the OBM Model

　　Different from ODM/OEM (original equipment manufacturer) manufacturing, projector OBM focuses on "brand independence + full-chain control." Its core goal is to differentiate its products through proprietary technologies (such as optical engines and cooling solutions), building a complete brand closed loop from R&D to market, and catering to diverse needs across various scenarios, including home, business, and education.

　　Product Positioning and Parameter Anchoring

　　Home Use: Features 4K resolution, high color gamut (≥95% DCI-P3), and low noise (≤26dB). Brightness ranges from 1500-3000 ANSI lumens, and supports MEMC motion compensation to meet movie viewing needs.

　　Business Use: Emphasizes portability (weight ≤2kg), fast startup (≤10 seconds), and keystone correction (±40°). Brightness ranges from 2000-4000 ANSI lumens, and is compatible with wireless projection protocols.

　　Education Use: Enhances durability (over 8 hours of daily use), dustproof design (IP5X rating), and large lens shift (vertical ±50%). Brightness ranges from 4000-6000 ANSI lumens, and supports multi-device simultaneous display.

　　Target Users and Differentiation Strategies

　　The home model targets young families aged 25-40, highlighting a "cinema-quality experience + smart home integration"; the business model targets small and medium-sized enterprises, emphasizing "efficient meetings + low-maintenance"; and the education model targets K12 and universities, featuring "high stability + eye protection certification (such as low blue light certification)."

　　II. Core Steps of the Full Development Process

　　R&D and Design Phase (6-8 Months)

　　Optical System Development:

　　Light Source Selection: Laser light sources (lifespan of over 20,000 hours) are preferred for home models; LED light sources (low cost and fast startup) are optional for business models; and ultra-high-pressure mercury lamps (high brightness) are used for educational models.

　　Lens Design: Customized in collaboration with professional optical manufacturers, home models support 1.2x zoom, while business models integrate fixed-focus short-throw lenses (throw ratio 0.8:1) to reduce installation space.

　　Imaging Chip: Compatible with DLP/LCD technology, 4K models use a 0.47-inch DMD chip, while 1080P models use a 0.33-inch DMD chip to ensure high image quality and clarity.

　　Heat Dissipation and Structural Design:

　　Cooling Solution: Utilizes a "multiple fans + vapor chamber + zoned air ducts" design. Core components (light source, chip) maintain a heat dissipation area of ≥150cm², preventing brightness degradation caused by high temperatures (measured temperature controlled within 60°C, brightness degradation ≤5%/year).

　　Structural Optimization: The home model uses an ABS+PC composite material (scratch-resistant and lightweight), the business model features a metal middle frame (drop-resistant), and the education model features anti-slip feet and a ceiling mount port on the bottom, adapting to various installation methods.

　　Circuit and Software Development:

　　Motherboard Design: Integrated power management (supporting a wide voltage range of 100-240V) and signal processing (HDMI 2.1 interface, supporting 4K 60Hz input) modules, utilizing an industrial-grade PCB (temperature resistant -20°C-85°C).

　　Firmware Development: A proprietary operating system supports autofocus, intelligent obstacle avoidance (recognizing wall obstacles), is compatible with third-party applications, and regularly delivers OTA updates for optimized features.

　　Supply Chain Management Stage

　　Core Component Supplier Classification:

　　Tier 1 Suppliers (Core Components): Suppliers of key components such as light sources, imaging chips, and lenses. Long-term supply agreements are required to ensure stable production capacity and quality, with a lead time of ≥ 3 months.

　　Tier 2 Suppliers (Auxiliary Components): Suppliers of components such as fans, housings, and interfaces. Class 100,000 cleanroom facilities are required, supporting customized production.

　　Tier 3 Suppliers (Consumables): Suppliers of consumables such as power cords and remote controls. Focusing on cost control and fast delivery, with a lead time of ≤ 15 days.

　　Supply Chain Risk Management:

　　Secure two to three alternative suppliers for key components to reduce the risk of a single supplier.

　　Establish a safety stock (core component inventory ≥ 1.5 times the monthly production volume) to mitigate risks such as chip shortages and logistics delays.

　　Manufacturing Phase (Mass Production Cycle: 1-2 Months)

　　Production Line Configuration:

　　Assembly Line: Utilizes a "semi-automatic assembly line + manual quality inspection" system, equipped with an optical tuning station (calibrating brightness and color uniformity) and a burn-in test station (running continuously for 4 hours at 45°C).

　　Testing Equipment: Equipped with a luminance meter, color analyzer, and electromagnetic compatibility (EMC) testing equipment to ensure each product meets factory standards.

　　Production Process Specifications:

　　Patch Phase: Component placement on the motherboard is completed in the SMT workshop (dust-free level 10000), with a yield rate requirement of ≥99.5%.

　　Assembly Phase: The optical engine, heat sink module, and housing are installed sequentially, using a torque wrench to control screw tightening to avoid component damage.

　　Testing Phase: Full functional testing (power on/off, signal input, and image quality output) and reliability testing (drop test from a height of 1.2 meters, vibration test at 5-500Hz). Defective products are individually marked and sent for repair, with a repair rate of less than 3%.

　　III. Quality Control System and Certification Standards

　　Full-Life Quality Control Key Points

　　Incoming Quality Control (IQC): Core components are randomly inspected for ≥10% of their total volume. Light sources are tested for brightness deviation (≤±3%) and lenses for transmittance (≥92%). Unqualified batches are returned in their entirety.

　　In-Process Quality Control (IPQC): Production lines are inspected every 2 hours, focusing on the heat dissipation module installation gap (≤0.5mm) and interface soldering quality. Inspection data is recorded.

　　Finished Product Quality Control (FQC): 100% inspection is conducted, testing key parameters such as brightness, color gamut, and noise. A test report is issued, and qualified products are affixed with the mandatory certification mark.

　　Compulsory and Voluntary Certifications

　　Compulsory Certifications: China 3C Certification (Electrical Safety, EMC), EU CE Certification, and US FCC Certification ensure product compliance.

　　Voluntary Certifications: Low Blue Light Certification (for home use), ISO 9001 Quality Management System Certification, and Energy Efficiency Certification (China Level 1 Energy Efficiency, standby power consumption ≤ 0.5W) enhance product competitiveness.

　　IV. Brand Operations and Market Strategy

　　Channel Development

　　Online Channels: Establish official flagship stores on major e-commerce platforms, open livestreaming rooms on major short video platforms, drive traffic through "product teardowns + scene demonstrations," and offer limited-edition giveaways (projection screens, brackets) during promotional events (such as major e-commerce shopping festivals).

　　Offline Channels: Establish experience stores in major home appliance chains, collaborate with interior design companies (embedded projection solutions), introduce business models to office supply stores, and connect educational models with school procurement tenders.

　　After-Sales Service System

　　Warranty Policy: Home models offer a 2-year full-machine warranty + a 5-year light source warranty; business models offer a 1-year full-machine warranty + a 3-year light source warranty; and education models offer a 3-year full-machine warranty.

　　Service Network: Establish a nationwide after-sales network (covering major cities), support on-site repairs (24-hour response in urban areas, 48 hours in suburban areas), and provide an online customer service hotline and remote debugging services (to resolve software issues).

　　Iteration and Innovation Plan

　　Short-term (1 year): Optimize firmware based on user feedback (such as adding voice control functionality) and launch customized housings (such as cartoon-style children's projectors).

　　Mid-term (2-3 years): Develop new technologies (such as short-throw laser TV solutions and 8K resolution models) and expand overseas markets (Southeast Asia, Europe, and other regions).

　　Long-term (5 years): Develop a smart projection ecosystem, integrate with mainstream smart home systems for deep integration, and build a competitive brand defense.

　　Tips for avoiding pitfalls: ① During the R&D stage, the core chip production capacity must be locked in 6 months in advance (the delivery cycle of core imaging chips is long) to avoid delays in mass production; ② During the production stage, the installation quality of the heat dissipation module must be strictly controlled. Poor heat dissipation will shorten the life of the light source by more than 30%; ③ For overseas markets, local voltage standards (such as 230V in Europe and 110V in the United States) and certification requirements must be investigated in advance to avoid compliance risks.
