Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single LED lighting systems are used, then the structure is simple, but the flexibility and versatility in controlling light parameters are limited
Solution Approach 1:
The lighting system is divided into multiple independent LED light sources (first LED light source, second LED light source, etc.) that can be selectively controlled. Each LED source can be independently enabled or disabled through the switch trigger mechanism, allowing flexible adjustment of light parameters without requiring a completely complex control system.
Solution Approach 2:
The patent implements dynamic control capability through the switch trigger mechanism that allows real-time adjustment of which LED sources are active. This dynamic switching enables the system to adapt to different lighting requirements while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple LED sources with different color temperatures are used, then the versatility and lighting quality are improved, but the device complexity increases
Solution Approach 1:
Different LED sources with different color temperatures (e.g., warm white, cool white) are segmented as independent controllable units. The switch trigger mechanism provides simple on/off control for each segment, avoiding the need for complex dimming or color mixing controls while still achieving versatile lighting effects.
Solution Approach 2:
Each LED source is designed with specific local quality characteristics (different color temperatures) to suit different lighting scenarios. The switch trigger allows users to select appropriate local qualities based on needs, achieving high versatility without requiring complex global control mechanisms.
3Use of energy by moving object
If LED modules are selectively enabled and disabled, then the energy efficiency is improved, but the control system complexity increases
Solution Approach 1:
The system dynamically adjusts energy consumption by enabling or disabling specific LED sources based on actual lighting needs. The switch trigger provides simple mechanical or electrical control for this dynamic adjustment, achieving energy efficiency without requiring complex power management circuits or control algorithms.
Solution Approach 2:
The patent extracts the essential control function into a simple switch trigger mechanism that directly controls the enabling/disabling of LED sources. This extraction avoids the need for complex integrated control systems while still achieving effective energy management through selective activation of lighting elements.

AI summary
A lighting apparatus includes a first light source, a second light source, a driver circuit, a main housing and a switch trigger. The switch base is coupled to the driver circuit. The house opening is disposed on a back side of the main housing. The back side of light source plate faces to the back side of the main housing. The switch trigger having a first end coupled to the switch base. The switch trigger extends through a plate opening of the light source plate to pass through the house opening to be operated by a user from the back side of the main housing. The switch trigger is operated to change a setting status of the switch base so as to change a light parameter for the driver circuit to control the first light source and the second light source.
