Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face recognition optics are integrated into the door pane, then personal identification is achieved, but space requirements conflict with other components
Solution Approach 1:
The patent merges the face recognition optical system with the existing transparent door pane structure. The camera and optical components are integrated into the pane assembly, combining the transparency function with the biometric identification function in a single unified structure, thereby eliminating the need for separate dedicated spaces.
Solution Approach 2:
The door pane is designed to serve multiple functions simultaneously: it maintains its primary function as a transparent barrier while also housing the face recognition camera and serving as the mounting structure for optical components. This multi-functionality reduces the overall space requirement by eliminating dedicated spaces for each function.
2Reliability
If three-dimensional face recognition is implemented, then deception resistance is improved, but space requirements increase further
Solution Approach 1:
The patent achieves three-dimensional facial recognition not by adding physical depth to the optical components, but by capturing and processing depth information through computational methods using two-dimensional image sensors. This dimensional transformation allows 3D recognition functionality within the constraints of a flat, space-constrained door pane environment.
Solution Approach 2:
The system replaces traditional bulky 3D optical sensors (such as structured light projectors or time-of-flight cameras) with a computationally-driven approach using standard 2D image sensors. By substituting mechanical/optical complexity with computational algorithms, the patent achieves 3D recognition capabilities while minimizing physical space requirements.
3Ease of operation
If holographic display or operating elements are added, then authentication is facilitated, but space requirements narrow further
Solution Approach 1:
The patent combines the holographic display function with the existing transparent pane structure. The display elements are integrated into the pane assembly, merging the information display function with the structural and optical functions of the door pane, thereby avoiding additional space consumption.
Solution Approach 2:
The holographic display utilizes thin-film technology that can be integrated into the transparent pane without significantly increasing its thickness or volume. This thin-film approach allows the display to be embedded within the existing pane structure, maintaining space efficiency while enabling enhanced authentication visualization.
