Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an X-Plate is used in the optical module, then the device complexity is reduced, but the image resolution deteriorates due to varying optical distances and assembly tolerances
Solution Approach 1:
The optical path processing assembly is divided into multiple functional components: combined lens, reflection mirror, and compensating lenses. Each component performs a specific function to control and equalize optical paths, replacing the single X-Plate structure and enabling precise optical distance control for each light-emitting display.
Solution Approach 2:
The patent uses compensating lenses with specific optical powers to adjust and equalize the optical distances of different light-emitting displays. By changing the optical parameters (focal length, position) of these lenses, the system compensates for variations in optical paths and achieves consistent image resolution across all displays.
2Productivity
If multiple light-emitting displays are arranged in the optical module, then the productivity increases, but the manufacturing precision deteriorates due to angular tolerances during bonding
Solution Approach 1:
The optical path processing assembly creates equipotential optical paths by ensuring that light rays from different light-emitting displays travel equal optical distances to the emergent surface. The combined lens and reflection mirror are positioned and designed such that all optical paths are equalized, making the system insensitive to minor angular variations in display arrangement.
Solution Approach 2:
The compensating lenses act as intermediary elements between the light-emitting displays and the emergent surface. These lenses compensate for angular tolerances and manufacturing variations by adjusting the optical paths, serving as a mediator that equalizes the effect of assembly variations on final image quality.
3Ease of operation
If the optical distance varies for different light-emitting displays, then the ease of operation increases, but the imaging quality deteriorates
Solution Approach 1:
The patent employs compensating lenses with specific optical parameters to adjust and equalize the optical distances. By carefully selecting the focal lengths and positions of these lenses, the system achieves equal optical paths for all light-emitting displays, thereby maintaining high imaging quality while preserving operational simplicity.
Solution Approach 2:
The optical path processing assembly provides a feedback mechanism where the combined lens and reflection mirror are positioned to reflect and redirect light rays such that the optical paths are equalized. This geometric configuration inherently compensates for variations and ensures consistent imaging quality across all displays.
