Universal Key Blank Carrier With Self-Aligning Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional key duplication systems require skilled workers to accurately select and position key blanks, leading to high rates of miscuts due to incorrect selection, insertion, or movement during cutting, resulting in duplicate keys that do not match the master key.
Innovation Solution
A key blank cutting carrier with mechanical alignment features and a flexible retaining clip that securely positions the key blank within a key cutter, allowing for accurate cutting without the need for separate clamps for each key type, using features like ridges, grooves, and asymmetrical shapes to ensure proper orientation and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional key duplication systems use separate clamps for each key type, then key blanks can be securely positioned during cutting, but device complexity increases and operation becomes more difficult
Solution Approach 1:
The patent implements a universal clamp design that can securely position multiple different key blank types using a single clamp mechanism. The clamp is designed with adjustable features and standardized interfaces that accommodate various key dimensions and shapes, eliminating the need for multiple specialized clamps while maintaining secure positioning reliability.
Solution Approach 2:
The key positioning system is segmented into modular components including the universal clamp, standardized key holder, and interchangeable positioning elements. This segmentation allows the single clamp to adapt to different key types by swapping positioning elements rather than requiring entirely different clamp assemblies for each key type.
2Manufacturing precision
If trained workers manually select and position key blanks, then accurate key duplication can be achieved, but loss of time increases due to skill requirements and operational complexity
Solution Approach 1:
The system incorporates self-aligning features on key blanks and standardized receptacles that automatically guide key blanks into the correct position during insertion. The asymmetric design elements and mechanical guides enable the key blank to self-position accurately without requiring skilled manual alignment, reducing both time and skill requirements while maintaining duplication accuracy.
Solution Approach 2:
Key blanks are pre-marked with identification codes and pre-configured with alignment features during manufacturing. The system pre-positions the key blank in the carrier before insertion into the cutter, with mechanical stops and guides that ensure correct orientation. This preliminary preparation eliminates the need for time-consuming manual selection and positioning steps during the duplication process.
3Device complexity
If key blanks are not securely clamped, then device complexity decreases, but manufacturing precision deteriorates due to key blank movement during cutting
Solution Approach 1:
The clamping mechanism applies localized pressure at specific contact points on the key blank using the universal clamp. The clamp design concentrates clamping force at critical locations to prevent movement during cutting while maintaining overall simplicity. The localized clamping approach achieves secure positioning without requiring complex multi-point clamping systems.

AI summary
Implementations of key blank carriers or key blanks with a standard reference features may include alignment features on a key blank head, key blank tip, a key blank carrier coupled to a key blank sleeve and/or a key blank sleeve, and any feature directly attached to any portion of the key that may be used for referencing in the key duplication system, or any combination of these. The standard reference features may allow any key blank brand model to interface with the machine so as to consistently align each key, regardless of its make and model, for cutting in a universally configured key blank clamp that is clamped to reduce the movement of the key blank during duplication cutting.
