Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the LED light bar and light guide plate are assembled first to improve brightness uniformity, then the brightness uniformity is improved, but the product yield becomes low and assembly efficiency becomes slow
Solution Approach 1:
The patent applies preliminary action by pre-assembling the LED light bar and light guide plate into an integrated assembly before mounting it on the backplane. This pre-assembly step ensures proper alignment and bonding between components, improving brightness uniformity while the jig maintains positioning accuracy during this preliminary assembly process.
Solution Approach 2:
The assembly jig serves as an intermediary device that facilitates the pre-assembly process. It provides a structured platform with positioning features that enable precise alignment of the LED light bar and light guide plate, acting as a mediator between the components and the final product assembly, thereby improving both quality and efficiency.
2Illumination intensity
If the LED light bar and light guide plate are assembled first to improve brightness uniformity, then the brightness uniformity is improved, but the product yield becomes low
Solution Approach 1:
The patent incorporates feedback mechanisms through the jig's positioning and alignment features that provide real-time guidance during assembly. The structured design allows operators to verify proper alignment and bonding, enabling immediate correction of assembly errors and reducing defective products, thus improving yield while maintaining brightness uniformity.
Solution Approach 2:
By performing the assembly of LED light bar and light guide plate as a preliminary step with the aid of the jig, potential assembly defects are identified and corrected early in the process. This preliminary assembly with proper positioning ensures high-quality bonding, preventing yield losses that would occur with misalignment or improper assembly.
3Productivity
If precise positioning and fixation of components are implemented to improve assembly efficiency, then the assembly efficiency is improved, but the device complexity increases
Solution Approach 1:
The assembly jig is segmented into distinct functional modules including positioning features, fixation mechanisms, and support structures. Each module performs a specific function, allowing for easier manufacturing, assembly, and maintenance. This segmentation enables precise positioning and fixation while keeping the overall device complexity manageable through modular design.
Solution Approach 2:
The jig is designed with universal features that can accommodate different component configurations and assembly requirements. The positioning and fixation mechanisms are versatile enough to handle various LED light bar and light guide plate arrangements, reducing the need for multiple specialized jigs and thereby managing complexity while improving assembly efficiency across different product variants.
