Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources with different color temperatures are installed to achieve color temperature changes, then the lighting effect is improved, but the device complexity and cost increase due to the need for separate lighting circuits
Solution Approach 1:
The patent merges multiple LED light sources with different color temperatures into a single integrated LED module. The control apparatus controls the current ratio guided into each LED light module through a single lighting circuit, eliminating the need for multiple separate circuits while maintaining the capability to achieve different color temperatures by adjusting current distribution among the integrated LED sources.
Solution Approach 2:
The single lighting circuit is designed to serve multiple functions by controlling multiple LED light sources with different color temperatures through current ratio adjustment. The control apparatus can dynamically switch between different color temperatures using the same circuit infrastructure, making the circuit universal and multi-functional rather than dedicated to a single color temperature.
2Adaptability or versatility
If multiple separate lighting circuits are used to control different color temperature light sources, then the color temperature control is improved, but the ease of operation deteriorates due to the need to incorporate new circuits into existing fixtures
Solution Approach 1:
The patent combines multiple LED light sources into a single LED module that can be controlled through one lighting circuit. This integration allows the replacement of traditional multi-circuit fixtures with a single-module solution that maintains color temperature control capabilities while simplifying installation and operation.
3Adaptability or versatility
If different light sources of unequal color temperatures are controlled separately, then the lighting effect is improved, but the loss of energy increases due to multiple circuits operating independently
Solution Approach 1:
The patent merges multiple LED light sources into a single controllable module, allowing centralized control of current distribution. This enables more efficient energy management by directing current only to the LED sources needed for the desired color temperature, rather than having multiple independent circuits that may operate inefficiently or remain idle.
