Shoe Lace Fastening Device with Click-Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lace bows require excessive lace material and are cumbersome for tying shoes, especially for sports and children's shoes, and do not provide a reliable or simple fastening solution.
Innovation Solution
A device comprising a base element with insertion grooves and a locking element that click-fits together to securely hold lace ends without tying, reducing the need for lace bows and allowing for identification chip integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lace bows are used to fasten shoes, then the laces can be tied and secured, but excessive lace material is required and the tying process becomes cumbersome
Solution Approach 1:
The device divides the lace into two separate ends that are inserted into separate insertion grooves in the base element, rather than requiring a continuous long lace to form a bow. This segmentation allows the lace to be much shorter while still achieving secure fastening, directly reducing lace material usage and simplifying the fastening operation.
Solution Approach 2:
The invention extracts and eliminates the bow-tying step from the traditional lacing process. By using a base element with insertion grooves and a locking element that secures the lace ends directly, the complex bow-tying operation is removed entirely, replacing it with a simple insert-and-lock action that is much easier to perform.
2Reliability
If conventional lace bows are used, then the laces can be fastened, but the fastening is not reliable and bows can become undone
Solution Approach 1:
The base element is divided into two separate insertion grooves that independently receive and secure each lace end. This segmentation ensures that each lace end is independently locked in place, preventing the bow from becoming undone while maintaining a relatively simple overall device structure.
Solution Approach 2:
The base element is pre-configured with insertion grooves and the locking element is pre-positioned to engage with these grooves. This preliminary arrangement ensures that when the lace ends are inserted, they are automatically secured in a reliable manner without requiring complex subsequent adjustments or tying operations.
3Productivity
If lace bows are tied to secure shoe laces, then the shoes can be fastened, but the process is cumbersome and time-consuming
Solution Approach 1:
The invention removes the time-consuming bow-tying process entirely from the fastening routine. By replacing it with a simple operation of inserting lace ends into pre-formed grooves and engaging a locking element, the fastening action becomes much faster and easier to perform, significantly improving productivity.
Solution Approach 2:
The base element and locking element are pre-configured during manufacturing with insertion grooves and engagement features already in place. This preliminary preparation allows the user to simply insert the lace ends and engage the lock without any complex manipulation, making the fastening process both faster and easier compared to traditional bow-tying.

AI summary
A device for connecting up two string ends, having a base element and at least one locking element which are hinged and can be click-fitted together. The base element has at least one opening for introducing the string ends and passing them through, and an insertion groove for each string end. Each insertion groove has a way, for example barb elements, for preventing the string end from sliding in said insertion groove. The locking element has a pressure part which is configured to cooperate with the respective insertion groove in such a manner that the string end is pressed into said insertion groove and remains pressed into said insertion groove after the base element and locking element have been click-fitted together.
