Snap-In Cord Lock for Custom Attachments Without Added Bulk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cord locks offer limited personalization options beyond color, shape, and material, lacking the ability to easily attach removable and customizable items.
Innovation Solution
A cord lock fastener device equipped with snap buttons that allow for the attachment of personalizing items, utilizing a spring-loaded mechanism with a snap button socket to securely hold decorative or functional elements without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If snap buttons are added to the cord lock fastener, then personalization capability is improved, but device complexity increases
Solution Approach 1:
The snap button socket is nested within the hollow portion of the housing, allowing the personalization feature to be integrated into the existing device structure without adding external complexity. The snap button mechanism is contained within the housing cavity, demonstrating the nesting principle where one component is placed inside another to save space and reduce overall device complexity.
Solution Approach 2:
The snap button socket is designed to accommodate various types of snap buttons and personalizing items, making the cord lock fastener versatile for different customization needs. This universal design allows the same structural component to serve multiple personalization functions, improving adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If personalizing items are attached to the cord lock fastener, then aesthetic customization is improved, but the device size increases
Solution Approach 1:
The personalizing items are attached to snap buttons that connect to the socket within the hollow portion of the housing. This nesting approach allows the personalization elements to be integrated into the existing device volume rather than adding external attachments that would increase the overall device size.
Solution Approach 2:
The snap button socket utilizes the internal hollow space of the housing, effectively using the third dimension (depth/internal volume) rather than expanding the external dimensions of the device. This allows personalization without increasing the device's external footprint.
3Adaptability or versatility
If a snap button socket is integrated into the cord lock fastener, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
The snap button socket is formed within the existing hollow portion of the housing, utilizing the pre-existing cavity space. This nesting approach allows the additional functionality to be integrated during the housing manufacturing process itself, rather than requiring separate assembly steps that would increase manufacturing complexity.
Solution Approach 2:
The snap button socket formation is combined with the housing manufacturing process, merging two functions (housing creation and socket integration) into a single manufacturing step. This reduces the number of separate manufacturing operations required and simplifies the overall production process.

AI summary
A cord lock for cords with a snap part. The cord lock device has a movable top part that forms a button that is pressed to release tension on a cord. When the button is released, the cord is held. The button has a pressing surface which is pressed to bring cord passing surfaces on first and second parts into communication with one another, to release tension on the cord passing through the cord passing surfaces. The pressing surface has a socket for a snap on device, which can be a decorative or useful snap in device.
