Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional optical systems are used to produce light effects, then light quality and effectiveness are maintained, but the device dimensions and weight increase significantly
Solution Approach 1:
The patent applies curved reflecting surfaces (hyperbolic or aspherical shapes) for both the primary and secondary mirrors. This curvature enables compact optical path folding while maintaining precise light beam control and quality, resolving the contradiction between reduced device volume and preserved illumination intensity
Solution Approach 2:
The patent uses a folded optical path configuration where light reflects between primary and secondary mirrors arranged in a compact three-dimensional geometry. This dimensional arrangement allows the optical system to achieve effective light transport in a reduced axial and lateral footprint while maintaining beam quality
2Ease of operation
If conventional optical systems are used, then light effects are produced effectively, but the device becomes heavy and bulky making it difficult to handle and transport
Solution Approach 1:
The curved hyperbolic or aspherical mirror surfaces enable a compact optical design that reduces overall device dimensions and weight while maintaining effective light beam production, thereby improving ease of handling and transport
Solution Approach 2:
The optical system employs a nested arrangement where the secondary mirror is positioned within the focal region of the primary mirror, and the light guide is integrated within the housing structure. This nesting minimizes the overall device envelope and weight while preserving optical effectiveness
3Productivity
If larger dimensional lighting devices are used, then high light efficiency is achieved, but the device complexity and installation time increase
Solution Approach 1:
The hyperbolic or aspherical mirror surfaces are optimized to maintain high light collection and redirection efficiency in a compact configuration, achieving comparable light efficiency to larger systems while enabling faster installation due to reduced dimensions
Solution Approach 2:
The patent integrates the light guide outlet, primary mirror, and secondary mirror into a compact unified optical assembly with a folded path. This merging of optical elements into a space-efficient configuration maintains light efficiency while reducing the overall device footprint for faster installation
