Pivoting Hook Rod Assembly for Back-Zipper Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zipper operating devices for back-positioned zippers are overly complex, increasing manufacturing difficulties and user issues due to elaborate mechanisms.
Innovation Solution
A rigid elongated rod with a pivotably coupled hook at one end for inserting into a zipper slider's eyelet, accompanied by a handle for easy operation, simplifying the engagement mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elaborate engagement mechanisms are used in zipper operating devices, then the zipper control effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential engagement function needed for zipper operation, eliminating unnecessary complex mechanisms. The hook design provides sufficient engagement capability through its simple geometric shape that catches onto the zipper slider, achieving reliable zipper control without elaborate mechanisms.
Solution Approach 2:
Instead of using complex mechanisms to achieve simple engagement, the patent inverts the approach by using a simple hook geometry that passively engages the zipper slider through its natural shape, allowing the slider to catch onto the hook rather than requiring an active engagement mechanism.
2Reliability
If elaborate engagement mechanisms are used in zipper operating devices, then the zipper control effectiveness is improved, but the manufacturing difficulty increases
Solution Approach 1:
The patent extracts only the essential engagement function needed for zipper operation, eliminating unnecessary complex mechanisms. The hook design provides sufficient engagement capability through its simple geometric shape that catches onto the zipper slider, achieving reliable zipper control without elaborate mechanisms.
Solution Approach 2:
The patent employs a simple hook design that can be manufactured inexpensively using basic forming processes. The rod and hook structure uses minimal material and can be produced through simple bending or forging operations, making the device cost-effective and easy to manufacture.
3Reliability
If elaborate engagement mechanisms are used in zipper operating devices, then the zipper control effectiveness is improved, but the usage problems increase
Solution Approach 1:
The hook design allows the zipper slider to automatically engage with the hook through its own movement and geometry. The slider's eyelet naturally catches onto the hook when the rod is inserted, eliminating the need for complex user-operated engagement mechanisms and reducing usage problems.
Solution Approach 2:
Instead of using complex mechanisms to achieve simple engagement, the patent inverts the approach by using a simple hook geometry that passively engages the zipper slider through its natural shape, allowing the slider to catch onto the hook rather than requiring an active engagement mechanism.

AI summary
A zipper operating device for operating a zipper attached to a garment and traversing part of a back of a user includes an elongated rod being rigid and having a first end and a second end. A hook is pivotably coupled to the first end of the elongated rod and is configured for insertion into an eyelet of a slider of a zipper. A method for using the device includes providing a garment with a zipper that traverses a portion of a back of a user. The hook is inserted into the eyelet and the elongated rod is moved such that the hook engages the slider to open or close the zipper.
