Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light guide member with multiple light source sections is used, then various emission patterns can be generated, but the device complexity increases due to multiple light source sections and corresponding light emitting sections
Solution Approach 1:
The light guide member is divided into multiple pattern forming sections, each containing light source sections and light emitting sections. Each section can independently control light emission patterns, allowing various emission patterns to be generated by selecting different light source sections while maintaining a modular structure that manages complexity.
Solution Approach 2:
A single light guide member serves multiple functions by incorporating multiple light source sections and light emitting sections that can generate various emission patterns. The light guide member acts as both a light transmission medium and a pattern formation element, eliminating the need for multiple separate components and reducing overall device complexity.
2Adaptability or versatility
If multiple light source sections are provided in the housing, then various emission patterns can be achieved, but the manufacturing complexity increases
Solution Approach 1:
The light guide member is pre-formed with multiple light emitting sections and pattern forming sections during manufacturing. The cut sections and reflecting surfaces are prepared in advance, allowing for easier assembly and reducing on-site manufacturing complexity. The housing is designed to accommodate multiple light source sections in predetermined positions.
Solution Approach 2:
Multiple functional elements are combined into integrated components: the light guide member integrates light transmission, pattern formation, and light emission functions. The housing combines support, alignment, and protection functions for multiple light source sections. This merging reduces the number of separate manufacturing processes required.
3Adaptability or versatility
If cut sections with reflecting surfaces are formed on the light guide member, then light can be selectively reflected to create emission patterns, but the manufacturing precision requirements increase
Solution Approach 1:
The light guide member features localized cut sections with reflecting surfaces at specific positions and orientations. Each cut section is precisely formed only where needed to reflect light from its corresponding light source section. This localized approach allows for controlled precision in critical areas while reducing overall manufacturing complexity in non-critical areas.
Solution Approach 2:
The patent replaces complex mechanical alignment systems with optically-formed reflecting surfaces. The cut sections are designed to passively reflect light at predetermined angles through their geometric shape rather than requiring active mechanical adjustment mechanisms, reducing the need for high-precision mechanical assemblies.
