Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a projection-type display device is used within an optical finder to superimpose electronic information on an optical image, then electronic information can be displayed on the optical image, but the alignment precision between the electronic information and the optical image deteriorates
Solution Approach 1:
The patent introduces a beam splitter as an intermediary component that divides the optical path into two separate paths: one for the optical image and another for the electronic information. This mediator allows both images to be processed independently and then combined, resolving the alignment precision issue by eliminating direct interference between the two image paths.
Solution Approach 2:
The patent segments the optical path into distinct channels using the beam splitter, separating the optical image path from the electronic information path. This segmentation allows each path to be optimized independently, with the electronic information being captured, processed, and aligned separately before being superimposed, thereby maintaining high alignment precision.
2Adaptability or versatility
If a zoom lens is used to capture images at different magnifications, then adaptability is improved, but parallax occurs between the optical image and the electronic information, worsening alignment precision
Solution Approach 1:
The patent employs feedback mechanisms where the imaging device captures the optical image, and the alignment processing unit uses this captured image as reference to dynamically adjust and align the electronic information. This feedback loop ensures that even when zoom magnification changes cause parallax, the electronic information remains precisely aligned with the corresponding optical image features.
Solution Approach 2:
The patent implements dynamic alignment processing that adapts to changing zoom magnifications. The alignment processing unit dynamically adjusts the positioning and scaling of electronic information based on the current optical image captured by the imaging device, allowing the system to maintain alignment precision across different zoom levels and magnifications.
