Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light guide plate optical system is used, then the structure is simple, but the light efficiency is low and multiple light-emitting effects cannot be achieved simultaneously
Solution Approach 1:
The optical system is segmented into two independent light guide structures (first light guide structure and second light guide structure), each capable of forming distinct light-emitting effects. This segmentation allows each structure to be optimized for specific light transmission paths, reducing light loss and improving overall light efficiency while maintaining manageable structural complexity
Solution Approach 2:
Two separate light guide structures are merged into a single integrated optical system that can simultaneously produce multiple light-emitting effects. The merging combines the advantages of multiple specialized light guides while sharing common support structures and control systems, thereby improving light efficiency without excessively increasing device complexity
2Device complexity
If a single light guide plate optical system is used, then the device complexity is low, but the versatility for multiple light-emitting effects and signal lamp functions is limited
Solution Approach 1:
The integrated optical system is designed with universal functionality by incorporating multiple light guide structures that can each produce different light-emitting effects. The system can simultaneously achieve various signal lamp functions (such as daytime running lights, turn signals, brake lights) with different colors and patterns, making a single optical system adaptable to multiple lighting requirements
Solution Approach 2:
The system transitions from a single-plane light guide structure to a multi-dimensional configuration with stacked first and second light guide structures. This dimensional change enables simultaneous light emission from different planes and angles, creating diverse light-emitting effects and signal functions without proportionally increasing structural complexity
3Adaptability or versatility
If multiple light guide structures are integrated, then multiple light-emitting effects can be achieved, but the device complexity increases
Solution Approach 1:
The first and second light guide structures are arranged in a nested or stacked configuration where they share common support structures, mounting brackets, and control electronics. This nesting approach allows multiple light guide structures to coexist in a compact arrangement, achieving multiple light-emitting effects while minimizing the increase in overall device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated optical system improves light efficiency by superimposing different light-emitting effects, optimizing space, and allowing for various light-emitting effects and signal functions with different colors.
Implementation Method 1
light emitted by a portion of the light sources enters the light guide plate from the light incident side of the light guide plate, and is reflected by the first reflecting surface and then emitted from the first light-emitting surface
Implementation Method 2
light emitted by another portion of the light sources enters the light guide structure from the light incident side of the light guide structure, and is reflected by the second reflecting surface and emitted from the second light-emitting surface
