Reciprocating Cord Lock Case for Intuitive Lace Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cord locks require a pulling operation to hold either the female or male member, making it difficult to release the fastening instinctively.
Innovation Solution
A cord lock design featuring a cylindrical case that reciprocates along a cylindrical axis, allowing the pulling operation to release fastening by engaging with both the female and male members through forward and backward movements, enabling release by holding any part of the case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cord lock structure requires holding only either the female member or the male member for pulling operation, then the fastening can be released, but the operation becomes difficult to perform instinctively
Solution Approach 1:
The patent combines the female member and male member into a single integrated cord lock body, where both fastening components are housed within one structure. This allows the user to hold and operate the entire device as a single unit rather than needing to manipulate separate components, thereby improving ease of operation while maintaining functional complexity through internal integration
2Ease of operation
If the case is designed to reciprocate along the cylindrical axis with engage-abutting portions, then the pulling operation can be performed by holding any part of the case, but the device structure becomes more complex
Solution Approach 1:
The case is designed with multiple engage-abutting portions positioned at different locations along the cylindrical axis, allowing the pulling operation to be initiated from any of these positions. This multi-functional design enables versatile operation where the user can grip the case at various points depending on convenience, while the internal reciprocating mechanism handles the complexity of engaging different fastening components

AI summary
A cord lock includes a cord lock main body as a case which houses the same. The cord lock main body is made such that locking on the cord is released by a pulling operation to reduce an insertion amount of a portion of a male member into an insertion passage. The case forms a cylindrical shape with openings on both ends through which the cord can pass and combines with the cord lock main body side in a manner allowing the case to be reciprocally moved along the cylinder axis direction. When the case is moved forward, the pulling action is made with a first engage-abutting portion of the case engaging an engage-abutted portion. When the case is moved backward, the pulling operation is made with a second engagement portion of the case engaging the engagement portion of the case engage-abutted portion of the male member.
