Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face images are pre-stored in a database and manual verification is used, then identification accuracy can be maintained, but the system response time becomes slow and productivity decreases
Solution Approach 1:
The patent replaces the mechanical/manual face image comparison system with an automated projection-based identification system. Instead of manually comparing stored face images, the system projects identification results directly onto surfaces, enabling rapid automated customer identification without manual verification, thus improving productivity while maintaining reliability through automated recognition algorithms.
Solution Approach 2:
The system enables self-service identification where customers are automatically identified through face recognition without requiring manual verification by staff. The projection display provides information directly to customers or relevant personnel, eliminating the need for manual database querying and comparison, thereby significantly reducing response time while maintaining accurate identification.
2Ease of manufacture
If conventional face recognition systems are used, then implementation is simple, but the system is limited to only a few types of applications and adaptability is poor
Solution Approach 1:
The patent creates a universal projection-based identification system that can serve multiple application types (restaurants, hotels, event venues, etc.) through a single core technology platform. The system projects identification results onto various surfaces (walls, ceilings, floors) and can be configured for different service scenarios, making it highly adaptable while maintaining ease of implementation through standardized projection device integration.
Solution Approach 2:
The system transitions from traditional 2D display screens to 3D projection surfaces, enabling information display in multiple spatial dimensions. This dimensional change allows the same identification system to be applied across different locations and scenarios by projecting onto various surfaces, significantly enhancing adaptability while keeping the core technology simple and easy to implement.
3Adaptability or versatility
If multiple projection devices are used to cover different locations, then service coverage is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple projection devices into a unified identification system where all projection units are controlled by a central management system. The devices work together as an integrated team, with the central system coordinating their operation, managing identification results across different locations, and synchronizing projection content, thereby achieving broad service coverage without proportionally increasing operational complexity.
Solution Approach 2:
The system implements feedback mechanisms where projection devices report their status and received identification results to the central management system. This feedback loop enables automatic coordination and optimization of multiple devices, allowing the system to dynamically adjust projection content and timing based on real-time conditions, thus managing complexity through intelligent automation rather than manual coordination.
