Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed lenses are used to control light direction, then light distribution is stable, but the system cannot be adjusted dynamically without mechanical intervention
Solution Approach 1:
The patent replaces mechanical lens adjustment systems with electro-active optical components that change their optical properties in response to applied electric fields. This substitution eliminates the need for mechanical moving parts while enabling dynamic control of light distribution patterns.
Solution Approach 2:
The patent utilizes electro-active optical components whose refractive index or optical density can be dynamically changed by applying different electric potentials. This allows the same optical component to produce different light distribution patterns without any mechanical movement, resolving the contradiction between adaptability and complexity.
2Ease of operation
If filters or cloudy materials are used to block light, then light direction can be controlled, but light energy transmission is reduced
Solution Approach 1:
The patent replaces absorptive filters and cloudy materials with electro-active optical components that redirect light through refraction rather than absorption. This substitution maintains high light energy transmission while achieving effective light direction control.
Solution Approach 2:
The patent uses electro-active optical components that change their refractive index in response to electric fields, enabling light redirection without the energy losses associated with absorptive materials. The components dynamically adjust their optical parameters to control light direction while preserving energy transmission.
