Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional optical lens imaging or integrated imaging or negative refractive index screen is used, then floating image can be formed, but the imaging size is small or resolution is low or ghost images exist
Solution Approach 1:
The patent divides the optical system into multiple optical units, each comprising optical elements arranged to form a portion of the floating image. By splicing multiple optical units together, the system achieves both high image quality and large image size, resolving the contradiction between small imaging size and high manufacturing precision
Solution Approach 2:
The patent combines multiple optical units with identical or similar structures to form a composite optical system. This merging approach allows the system to maintain the high image quality of individual units while achieving large overall image size through the collective contribution of multiple units
2Adaptability or versatility
If different sized floating display apparatuses are designed for different users' needs, then image size requirements are met, but manufacturing costs and resource consumption increase
Solution Approach 1:
The patent designs optical units with identical or similar structures that can be used universally across different configurations. By splicing different numbers of these universal optical units together, the system can adapt to various image size requirements without requiring separate designs, thereby reducing manufacturing costs and improving versatility
Solution Approach 2:
The patent enables dynamic configuration of the optical system by allowing optical units to be spliced in different quantities and arrangements. This dynamic adaptability allows the same basic optical unit design to serve multiple image size requirements, reducing the need for custom manufacturing and lowering costs
3Adaptability or versatility
If multiple optical systems are designed for different image sizes, then various size requirements are satisfied, but device complexity and design resources increase
Solution Approach 1:
The patent segments the optical system into standardized, modular optical units that can be independently designed and manufactured. This segmentation reduces the complexity of designing entire optical systems from scratch, as each unit follows a standardized structure that can be replicated and spliced to achieve different overall configurations
Solution Approach 2:
The patent creates universal optical units that can serve multiple functions and configurations. By using the same basic optical unit design for different image sizes through splicing, the system reduces design complexity while maintaining adaptability to various size requirements
