Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of key blanks is used, then operator flexibility is maintained, but accuracy and reliability of key duplication deteriorate due to human error
Solution Approach 1:
The patent replaces the manual mechanical selection process with an optical imaging system and logic-based automated identification system. The optical device captures images of key blanks, and the logic systematically analyzes them to identify the correct blank, eliminating reliance on operator visual inspection and manual selection.
Solution Approach 2:
The system enables self-service by allowing the key duplication machine to automatically identify and select the correct key blank without operator intervention. The optical imaging device and logic work together to autonomously determine which blank matches the master key pattern, making the machine self-sufficient in the selection process.
2Measurement precision
If automated optical identification system is implemented, then accuracy and reliability improve, but device complexity increases
Solution Approach 1:
The patent uses optical imaging to create a digital copy or representation of the key blank's physical characteristics. The optical device captures an image of the blank, and the logic analyzes this image data to identify matching patterns, effectively using a visual copy rather than direct physical measurement to determine compatibility.
3Productivity
If manual key blank identification process is used, then device simplicity is maintained, but productivity deteriorates due to time-consuming selection process
Solution Approach 1:
The system performs preliminary action by pre-capturing and storing optical images of multiple key blanks before the duplication process begins. When a duplication is needed, the logic quickly compares the master key pattern against these pre-captured images to identify the correct blank, eliminating the time required for manual inspection during the actual duplication process.
