Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed wall switch is used to control LED lights with adjustable functions, then the control function is achieved, but the convenience of use deteriorates due to distance between the lighting area and the switch
Solution Approach 1:
The patent combines the switch with the LED light fixture itself, integrating the control function into the lighting device. The switch is mounted on the light fixture housing and operates in conjunction with the LED modules, eliminating the need for a separate wall switch and improving accessibility.
Solution Approach 2:
The LED light fixture integrates multiple functions including lighting, dimming control, and color temperature adjustment within a single device. The switch controls multiple parameters (brightness and color temperature) simultaneously, reducing the need for separate control devices and improving operational convenience.
2Adaptability or versatility
If a wireless switch is used to control LED lights, then the flexibility of control is improved, but the ease of operation deteriorates because the switch is difficult to find
Solution Approach 1:
The control switch is physically integrated into the LED light fixture, combining the lighting function and control function in one location. This ensures the switch is always visible and accessible near the light source, eliminating the problem of losing or misplacing a separate wireless switch.
3Use of energy by moving object
If conventional LED lights replace incandescent or fluorescent lights, then energy efficiency is improved, but the cost increases due to the need to modify and replace the switch
Solution Approach 1:
The switch is integrated into the LED light fixture assembly, so when the LED bulb is replaced, the switch remains part of the new fixture. This eliminates the need to separately modify or replace wall switches when upgrading from incandescent or fluorescent lighting to LED, reducing overall replacement costs.
Solution Approach 2:
The integrated switch design provides universal control for LED fixtures with various functions (dimming, color temperature adjustment). This multi-functional switch works across different LED bulb types and installations, reducing the need for custom wiring or switch modifications during replacement.
4Adaptability or versatility
If LED lights with adjustable light intensity and color temperature are provided, then functionality is improved, but the device complexity increases
Solution Approach 1:
Multiple LED modules with different color temperatures (warm white, cool white, etc.) are integrated into a single fixture, along with a unified switch that controls all modules. This combines multiple lighting functions into one device while maintaining relatively simple control architecture.
Solution Approach 2:
The LED fixture dynamically adjusts light output by controlling different LED modules based on switch position. The system can vary brightness levels and color temperature combinations dynamically, providing adjustable functionality while using a simple mechanical switch rather than complex electronic controls.
