Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual worktable mechanisms are used, then device complexity is reduced, but manufacturing precision and work efficiency deteriorate
Solution Approach 1:
The patent replaces the manual mechanical worktable mechanism with an automated reset mechanism driven by a control system. The control system automatically triggers the reset operation after key duplication, eliminating manual manipulation while achieving precise worktable positioning and resetting, thus resolving the contradiction between device complexity and manufacturing precision.
2Device complexity
If manual worktable mechanisms are used, then device complexity is reduced, but work efficiency deteriorates
Solution Approach 1:
The reset mechanism is designed to automatically execute the worktable reset operation without requiring manual intervention. After the key duplication process completes, the control system autonomously triggers the reset sequence, allowing the worktable to return to its initial position automatically. This self-service capability eliminates idle time and manual operations, significantly improving work efficiency while maintaining reasonable device complexity.
3Extent of automation
If semi-automatic reset operation is required, then automation level is reduced, but ease of operation deteriorates
Solution Approach 1:
The control system is programmed to automatically detect when the key duplication process is complete and autonomously trigger the reset mechanism. The user simply needs to initiate the duplication process; all subsequent operations including the reset are performed automatically. This full automation eliminates the need for manual reset button pressing, greatly improving ease of operation while maintaining high automation level.

Function Achieved in This Case
The reset mechanism simplifies operations, enhances precision, and improves user experience by enabling automatic return of the worktable, reducing manual effort and increasing efficiency while adhering to ergonomic design principles.
Implementation Method 1
The elastic member is a torsion spring mounted on the spindle; a first torsion arm of the torsion spring is connected with the body which always tends to move towards workspace

AI summary
The invention relates to a reset mechanism of the key duplication device which comprises a reset apparatus (1), a spindle (3) and a body (4), wherein the spindle (3) is inserted into the body (4) and is rotatably connected to the body (4). Between workspace and a loading area, the body (4) is repeatedly moveable along the spindle (3). The reset mechanism comprises an elastic member (11) connected with the body (4). Elastic forces of the elastic member (11) always act on the body (4) and move the body (4) toward the workspace. After the body (4) is rotated to the loading area against the elastic forces of the elastic member (11), when a withdrawal force exceeds the elastic forces, the body (4) automatically returns to the workspace under the influence of the elastic forces. The fewer and easier operating steps and the more efficient work of the reset mechanism make the mechanism conforming to ergonomic design.
