Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the beam angle is adjusted by adjusting the distance between the LED light source and a lens, then the beam angle can be changed, but the adjustment mechanism becomes complex, the adjustment accuracy is poor, and optical devices are damaged easily
Solution Approach 1:
The patent applies the dynamics principle by making the optical component rotatable to dynamically switch between different light exiting portions. Instead of adjusting the distance between the LED light source and lens, the patent rotates the optical component to select different beam angles, transforming a complex mechanical adjustment into a simple rotational switching mechanism that maintains adaptability while reducing complexity.
2Adaptability or versatility
If multiple lighting effects are provided by purchasing multiple lighting devices, then different lighting requirements are met, but the device complexity and cost increase
Solution Approach 1:
The patent applies the universality principle by designing a single lighting device that can provide multiple lighting effects through different combinations of color temperatures and beam angles. The lighting device includes light sources with different color temperatures and an optical component with multiple light exiting portions that provide different beam angles, allowing one device to replace multiple devices and achieve various lighting scenarios.
Solution Approach 2:
The patent applies the merging principle by combining multiple light sources with different color temperatures and multiple optical components with different beam angles into a single integrated lighting device. This consolidation allows the device to provide diverse lighting effects while reducing the overall system complexity and eliminating the need for multiple separate devices.
3Adaptability or versatility
If the lighting device provides multiple color temperatures and beam angles, then lighting versatility is improved, but the structural complexity increases
Solution Approach 1:
The patent applies the segmentation principle by dividing the optical component into multiple separate light exiting portions, each designed to provide a specific beam angle. The optical component includes a first light exiting portion for a first beam angle and a second light exiting portion for a second beam angle. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural simplicity through modular design.
