Telescopic Zipper Puller for Hard-to-Reach Clothing Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals face difficulties in accessing and operating hard-to-reach zippers on clothing without assistance, particularly during wardrobe malfunctions, as existing solutions do not provide an effective and adjustable extension mechanism.
Innovation Solution
A zipper puller device comprising an ergonomic handle, a telescopic shaft, and a hook that attaches to a recovery aperture on the zipper pull tab, allowing for adjustable extension and easy operation of zippers, including securing the zipper to a button or safety pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a fixed-length zipper puller is used, then the structure is simple, but it cannot reach hard-to-access zippers
Solution Approach 1:
The patent applies the dynamics principle by implementing a telescopic shaft that can extend and retract, transforming the fixed-length puller into a variable-length tool. This allows the device to adapt its reach distance based on the specific zipper location, solving the contradiction between achieving extended reach and maintaining structural simplicity.
2Ease of operation
If a telescopic shaft is added to extend reach, then hard-to-reach zippers can be accessed, but the device becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the telescopic shaft into multiple collapsible sections that can be independently extended or retracted. This modular approach allows the device to achieve extended reach while maintaining a compact form when not in use, and enables selective activation of only the necessary sections for each specific task.
3Adaptability or versatility
If the telescopic shaft is made adjustable, then it can adapt to different zipper positions, but the mechanism becomes more complex
Solution Approach 1:
The patent applies the nested doll principle by designing the telescopic shaft with sections that nest within each other when retracted, similar to Russian nesting dolls. This allows the adjustable mechanism to maintain a compact profile while providing multiple extension positions, reducing the visual and spatial complexity despite the adjustable functionality.

AI summary
The zipper puller device is configured for use with the pull tab of a zipper. The pull tab is further defined with a recovery aperture. The zipper puller device is an extension structure. Specifically, the zipper puller device extends the reach of an individual such that a hard to reach zipper may be secured by the individual without assistance. The span of the extension provided by the zipper puller device is adjustable. The zipper puller device comprises an ergonomic handle, a telescopic shaft, and a hook. The telescopic shaft attaches the hook to the ergonomic handle. The hook attaches to the recovery aperture. The handle manipulates the hook when the zipper puller device is in use. The span of the length of the telescopic shaft is adjustable.
