Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional optical modules with separated structures are used, then the device complexity is reduced and manufacturing is easier, but the lighting image appears intermittent and cannot achieve continuous linear shape
Solution Approach 1:
The patent merges multiple optical modules into a single integrated unit, combining multiple light sources and condensing lenses that were previously separated. This integration creates a unified optical system that generates continuous linear lighting images without intermittent gaps, directly resolving the shape continuity issue while managing the increased structural complexity through unified design.
Solution Approach 2:
The patent arranges multiple optical modules in a vertical direction rather than horizontal separation, creating a multi-dimensional configuration. This vertical stacking with specific curvature relationships between lenses produces continuous linear lighting patterns, transforming the spatial arrangement to achieve the desired lighting shape while organizing the complex structure vertically.
2Shape
If multiple optical modules are arranged vertically with specific curvature relationships, then continuous linear lighting image is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies precise curvature parameters for the condensing lenses, with the first condensing lens having a first curvature and the second condensing lens having a second curvature that differs from the first. By carefully controlling and differentiating these curvature parameters, the system achieves continuous linear lighting images while providing clear manufacturing specifications that guide precision requirements.
Solution Approach 2:
The patent applies different curvature characteristics to different parts of the optical system - the first condensing lens has one curvature configuration while the second condensing lens has a different curvature configuration. This local differentiation of optical properties allows each lens to contribute specifically to creating the continuous linear lighting pattern, with each component optimized for its local function.
3Adaptability or versatility
If conventional separated optical modules are used, then heat dissipation is simpler, but design differentiation is limited
Solution Approach 1:
The patent combines multiple optical modules into an integrated unit with unified structure, enabling new design possibilities and visual patterns that were not achievable with separated modules. This merging creates distinctive continuous linear lighting signatures that enhance design differentiation while the integrated nature manages thermal characteristics through the unified structure.
Solution Approach 2:
The patent employs curved surfaces and spherical lens elements in the integrated optical module design, with specific curvature relationships between components. This use of curvature not only achieves the optical function of continuous linear lighting but also contributes to aesthetic design differentiation, making the lamp visually distinctive while maintaining functional integration.
