Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple filter films and prisms are used for light transmission, then light can be filtered and transmitted through multiple wavelengths, but energy loss increases due to gaps between components and multiple refractions
Solution Approach 1:
The patent merges multiple separate filter films and prisms into a single integrated optical element. The filter films are attached directly to the prisms without gaps, creating a unified structure that eliminates energy loss from gaps while maintaining the ability to filter and transmit multiple wavelengths of light
Solution Approach 2:
The optical element serves multiple functions simultaneously: it acts as both a filter for different wavelengths and a prism for light deviation. This multi-functional design eliminates the need for separate components, reducing the number of interfaces and associated energy losses
2Measurement precision
If fixed angles of multiple prisms are used, then each wavelength can be refracted at specific angles, but energy loss increases due to varying refractions of different wavelengths
Solution Approach 1:
The patent applies different local properties to different regions of the optical element. Each prism region is optimized for specific wavelength ranges with appropriate angles, while the overall structure maintains continuity. This allows precise wavelength separation without the energy losses associated with multiple discrete components
3Ease of manufacture
If gaps are defined among multiple prisms and filter films, then assembly is simplified, but energy loss increases as light passes through multiple mediums
Solution Approach 1:
The filter films are attached directly to the prism surfaces, eliminating gaps between components. This integrated approach maintains manufacturing simplicity while eliminating energy loss from gap-related reflections and refractions
