Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials are used for the light guiding structure and holding portion, then structural strength and stability are improved, but light leakage occurs and assembly flexibility is reduced
Solution Approach 1:
The patent applies this principle by using a soft material (such as silicone rubber) for the light guiding structure and holding portion. This flexible material conforms to the circuit substrate surface, creating effective light leakage prevention through contact pressure while maintaining structural integrity. The soft material acts as both a structural component and a light blocking element, eliminating the need for separate light blocking components.
Solution Approach 2:
The patent employs composite material principles by integrating multiple functions into a single soft material component. The soft material serves simultaneously as a light guiding structure, holding portion, and light blocking element. This multi-functional composite approach resolves the contradiction by combining the flexibility and conformability of soft materials with the structural requirements of the mounting bracket.
2Manufacturing precision
If rigid components are used for mounting bracket and light guide, then assembly precision is improved, but adaptability to different circuit substrates is reduced
Solution Approach 1:
The soft material (e.g., silicone rubber) in the mounting bracket and light guide structure provides flexibility to adapt to different circuit substrate surfaces while maintaining precise positioning. The material deforms to conform to the substrate geometry, ensuring reliable contact and light leakage prevention across various substrate types and configurations.
Solution Approach 2:
The patent utilizes the ability of soft materials to change their physical parameters (shape, volume) under compression to achieve precise assembly. When the soft material is compressed during assembly, it deforms to match the circuit substrate surface, providing both adaptability and assembly precision without requiring rigid, substrate-specific components.
3Object-generated harmful factors
If additional light blocking components are added to prevent light leakage, then light leakage prevention is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent merges the light guiding structure, holding portion, and light blocking function into a single integrated soft material component. The soft material simultaneously performs structural support, light guidance, and light leakage prevention functions, eliminating the need for separate light blocking components and reducing overall device complexity.
Solution Approach 2:
The soft material component is designed to perform multiple functions: it acts as a light guiding structure, provides holding capability for the circuit substrate, and prevents light leakage. This multi-functional design simplifies the device by consolidating what would traditionally require multiple separate components into a single universal element.
4Ease of operation
If soft materials are used for light guiding structure and holding portion, then light leakage prevention and assembly flexibility are improved, but structural strength is reduced
Solution Approach 1:
The soft material (such as silicone rubber) provides sufficient structural strength for the application while maintaining flexibility for easy assembly. The material's elasticity allows it to deform during assembly and then maintain stable contact pressure for light leakage prevention, achieving both assembly flexibility and adequate structural strength.
Solution Approach 2:
The soft material's ability to deform and conform to curved surfaces enables effective light leakage prevention through contact pressure. The material can be compressed to create a conformal interface with the circuit substrate, providing both assembly flexibility and the necessary structural integrity for light guidance and holding functions.
