Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If magnetic attraction is used to secure the display module, then the assembly process is simplified, but instantaneous bumps occur reducing yield and stability
Solution Approach 1:
The patent replaces the magnetic attraction system with a mechanical clamping system. The clamping module includes clamping arms that can be positioned and secured to hold the display module firmly against the box body, eliminating the bumping issue caused by magnetic attraction while maintaining ease of assembly through the structured clamping mechanism
Solution Approach 2:
The patent introduces positioning posts and clamping arms as intermediary mechanical elements between the box body and the display module. These intermediaries provide a stable, bump-free connection by distributing the holding force through multiple contact points rather than relying on magnetic attraction alone
2Manufacturing precision
If glass or quartz substrates are used for Mini/Micro-LED displays, then display quality is improved, but the substrates are more prone to instantaneous bumps during assembly
Solution Approach 1:
The patent implements a clamping mechanism with clamping arms that apply controlled, distributed pressure to the glass or quartz substrate beforehand during assembly. This prevents instantaneous bumps by providing continuous mechanical support and positioning across multiple points, protecting the fragile high-quality substrate from damage
3Reliability
If a clamping mechanism with multiple components is used to eliminate bumps, then module stability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components. The clamping module combines positioning, clamping, and securing functions into a single assembly unit that works together with the positioning posts. This integration reduces the overall complexity compared to having separate magnetic components, positioning mechanisms, and securing elements
Solution Approach 2:
The positioning posts serve multiple functions: they provide structural support, enable precise positioning of the display module, and work as anchor points for the clamping arms. This multi-functionality reduces the need for additional separate components, maintaining simplicity while achieving high connection stability
