Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix structural components, then the connection strength is improved, but the mounting time increases and production efficiency decreases
Solution Approach 1:
The patent replaces the traditional screw-based mechanical connection system with a snap-fit mechanism consisting of clamping blocks and clamping slots. The clamping blocks protrude from the rear cover and engage with corresponding slots in the light guide plate, providing secure fixation without requiring screws, thereby significantly reducing mounting time and improving production efficiency while maintaining connection strength
Solution Approach 2:
The patent divides the connection structure into separate functional components: clamping blocks integrated into the rear cover and clamping slots formed in the light guide plate. This segmentation allows for modular assembly where components can be manufactured independently and then quickly assembled together through the snap-fit mechanism, eliminating the need for separate fastening operations
2Reliability
If multiple screw materials are used for fixation, then the connection reliability is improved, but the risk of production abnormalities increases
Solution Approach 1:
The patent employs a universal connection mechanism where the clamping blocks and slots provide a standardized interface for securing multiple different components (light guide plate, diffusion plate, reflective sheet) using the same basic structure. This eliminates the need for different screw types and materials for different components, reducing production complexity and minimizing the risk of production abnormalities while maintaining reliable connections across all assemblies
Solution Approach 2:
The patent uses a homogeneous connection approach where all structural components are secured using the same snap-fit mechanism with identical clamping blocks and slots. This uniformity in connection method simplifies the manufacturing process, reduces the variety of fastening materials needed, and minimizes potential production issues related to material compatibility and assembly variations
3Productivity
If clamping blocks are rotated into clamping slots, then the mounting speed is improved, but the risk of misalignment increases
Solution Approach 1:
The patent incorporates asymmetric features in the clamping blocks and slots, including positioning protrusions and corresponding recesses, as well as限位 (limiting) structures. These asymmetric elements guide the components into correct alignment during the rotation assembly process, ensuring that the clamping blocks engage with the slots at the proper orientation and position, thereby preventing misalignment while maintaining fast mounting speed
