Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED light sources are designed with specific illumination angles using fixed circuit boards, then the illumination angle is achieved, but redesigning circuit boards is required for different sizes and configurations
Solution Approach 1:
The patent divides the LED light source into modular components: LED modules that can be independently configured and connected to circuit boards. This segmentation allows different numbers and arrangements of LED modules to be used on the same circuit board design, eliminating the need to redesign circuit boards for different sizes and configurations.
2Ease of manufacture
If LEDs are arranged with propagation directions perpendicular to substrates, then manufacturing is simplified, but illumination efficiency deteriorates due to inconsistency between LED light direction and light source emission direction
Solution Approach 1:
The patent introduces adjustable angle structures that allow the propagation direction of LED emergent light to be dynamically adjusted to match the propagation direction of the light source. This dynamic adjustment capability enables optimal illumination efficiency while maintaining manufacturing simplicity, as the physical arrangement can be adapted without changing the fundamental perpendicular mounting approach.
3Reliability
If independent light source controllers are used for each LED light source, then control precision is improved, but system cost and volume increase
Solution Approach 1:
The patent merges the light source controller functionality into a shared controller that can control multiple LED light sources simultaneously. This consolidation maintains control precision through dedicated control circuits while significantly reducing system volume and complexity by eliminating the need for separate independent controllers for each light source.
4Reliability
If flash synchronized triggering is achieved through external devices, then synchronization capability is provided, but delay time increases
Solution Approach 1:
The patent implements preliminary action by having the light source controller ready to receive and respond to flash synchronized trigger signals immediately. The controller is pre-configured with the necessary circuitry and logic to process trigger signals without requiring external processing delays, enabling rapid response and minimizing triggering delay while maintaining reliable flash synchronization.
