Zipper Pull System with Pulley Mounts for Partition Entryways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partition systems in construction zones often result in damage to surfaces due to inadequate installation methods, and contemporary entryway mechanisms require manual operation, which can be inconvenient and inefficient.
Innovation Solution
A system comprising pulleys, pulley mounts, and an elongated pull mechanism that securely couples to a zipper, allowing for easy opening and closing of a partition without manual bending, while preventing surface damage during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual zipper operation is used, then the entryway mechanism is simple, but it requires manual bending and is inconvenient
Solution Approach 1:
The patent transforms the vertical zipper pull motion into horizontal motion by routing the pull through pulleys mounted on the curtain edges. The pull string extends horizontally from the zipper, allowing users to operate the zipper without bending, while the pulley system converts this horizontal pull into the vertical motion needed to move the zipper tab.
Solution Approach 2:
The patent introduces pulleys and a pull string as intermediary elements between the user and the zipper. Instead of directly grasping and moving the zipper tab vertically, users pull on the horizontal string, and the pulleys mediate the force transmission to move the zipper, eliminating the need for manual bending.
2Ease of manufacture
If tape or adhesives are used to install partitions, then installation is simple, but paint is removed or adhesive is difficult to remove
Solution Approach 1:
The patent extracts the harmful adhesive or tape from the installation process entirely. Instead of using adhesives that damage surfaces, the system employs spring-biased pole mounts that mechanically secure the curtain to the floor and ceiling without any adhesive, eliminating paint removal and adhesive residue problems.
Solution Approach 2:
The patent uses temporary, non-damaging mounting methods where the pole mounts can be easily installed and removed without leaving traces. The spring-biased design allows for quick installation by simply inserting poles into the floor and ceiling, and easy removal by withdrawing them, with no surface damage incurred.
3Ease of manufacture
If spring-biased pole mounts are used, then installation is clean and easy, but sag or gaps may be present in the curtain
Solution Approach 1:
The patent incorporates a tensioning mechanism that is pre-configured in the pole mount system. The spring bias is calibrated to apply sufficient tension to the curtain at installation, automatically eliminating sag and gaps before the curtain is even used. This preliminary tensioning action ensures proper alignment without requiring additional adjustment steps.
Solution Approach 2:
The patent uses adjustable spring tension parameters in the pole mounts to optimize curtain tension. By varying the spring force parameter, the system can compensate for different curtain weights and materials, maintaining consistent tension and eliminating sag across various installation scenarios without compromising the ease of installation.

AI summary
A system, comprises a first pulley and a first pulley mount constructed and arranged to couple the first pulley to a curtain including a zipper. The first pulley mount comprises a first portion and a second portion that are removably coupled to each other with a portion of the curtain between them when mounted to the curtain. A second pulley in included along with a second pulley mount constructed and arranged to couple the second pulley in position relative to the curtain. An elongated pull is coupled to the first pulley, the second pulley, and a zipper pull of the zipper.
