Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing numerically controlled key duplicating machines have a large and less compact structure, making them inconvenient to carry and use, and their exposed feeding mechanisms allow processing residues to contaminate the drive area, affecting processing precision and machine stability.
Innovation Solution
A key duplicating machine with a base comprising a vertical and horizontal plate that separates the processing area from the drive area, incorporating a feeding device with guide rails and a sealing component to prevent residues from entering the drive area, and a detecting device for precise key positioning and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the feeding mechanism is exposed and directly connected to the processing mechanism, then the structure is simpler and easier to manufacture, but processing residues can invade the movable guide rail, affecting processing precision and machine stability
Solution Approach 1:
The patent divides the machine into two distinct areas: a processing area where key duplication occurs and a drive area containing the guide rails and feeding mechanism. This spatial segmentation prevents processing residues from contaminating the drive area, thereby maintaining processing precision while preserving structural simplicity.
Solution Approach 2:
The patent introduces a sealing component as an intermediary barrier between the processing area and the drive area. This sealing component allows the feeding mechanism to remain exposed and simple while preventing residues from reaching the movable guide rail, thus resolving the contradiction between structural simplicity and processing precision.
2Device complexity
If the feeding mechanism is exposed and directly connected to the processing mechanism, then the structure is simpler, but the protective performance is weakened and processing residues can easily invade the movable guide rail
Solution Approach 1:
The sealing component serves as a protective intermediary that shields the drive area from processing residues without adding significant structural complexity. It maintains the exposed feeding mechanism while enhancing protective performance.
Solution Approach 2:
The patent extracts the vulnerable drive area components (guide rails, feeding mechanism) from the processing area by separating them into distinct spatial zones. This extraction protects the drive area from residue contamination while maintaining overall structural simplicity.
3Manufacturing precision
If a sealing component is added to separate the processing area from the drive area, then processing precision and machine stability are improved, but the device complexity increases
Solution Approach 1:
The sealing component is designed as a minimal-intervention intermediary that provides effective protection with minimal added complexity. It creates the necessary separation between processing and drive areas without significantly increasing device complexity.
Solution Approach 2:
The sealing component appears to be implemented as a thin film or flexible barrier that effectively separates the two areas while adding minimal structural complexity. This approach maintains processing precision without substantially increasing device complexity.

AI summary
This invention provides a key duplicating machine and its duplicating method, comprises a base (1), a main axis processing device (2), a detecting device (3), a feeding device (4), a clamping device (5) and a drive device. The base (1) comprises a vertical plate (12) and a horizontal plate (11), separates the horizontal plate (11) into a front part and a rear part. The main axis processing device (2) and the detecting device (3) are both flexibly connected to the vertical plate (12) and arranged on the side facing the front part. The base (1) separates the processing area from the drive area so that processing residues produced in the processing area will not easily invade the drive area, ensuring that the drive area will be clean and free from contamination, reducing the probability of damage to the motor, guide rail (431, 432) and other structures in the drive area, and increasing the stability and lifespan of the key duplicating machine.
