Insect Screen Double Closure Magnetic Zipper System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect protection devices for open access openings, such as those in recreation rooms or vehicles, are not user-friendly due to the need to operate a zipper every time access is needed, compromising ease of use and reliability.
Innovation Solution
A double closure system featuring an inner zipper and an outer magnetic closure, where the magnetic closure automatically re-engages after passage, eliminating the need for manual operation and ensuring insect-proof sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a zipper is used as the closure device for the subdivision of the cover net, then the contour stability and assembly reliability are improved, but the ease of operation deteriorates due to the need to manually operate the zipper each time access is needed
Solution Approach 1:
The closure device is segmented into two independent closures arranged one behind the other: an inner zipper closure and an outer magnetic closure. The zipper provides reliable form-fitting connection for contour stability, while the magnetic closure enables automatic closing without manual operation, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The magnetic closure component enables the closure system to serve itself by automatically closing after each passage through magnetic attraction, eliminating the need for manual zipper operation. This self-closing mechanism maintains reliability while dramatically improving ease of operation
2Ease of manufacture
If a zipper is used as the closure device, then the assembly simplicity is improved, but the user-friendliness deteriorates due to frequent manual operation requirements
Solution Approach 1:
The closure device is divided into two independent functional components: the zipper for assembly and the magnetic closure for automatic operation. This segmentation allows the system to maintain assembly simplicity while achieving high user-friendliness through automatic closing
Solution Approach 2:
The manual mechanical operation of the zipper is partially replaced by a magnetic field-based automatic closing mechanism. The magnetic attraction force automatically pulls the magnetic closure components together, eliminating the need for manual manipulation and significantly improving user-friendliness
3Ease of operation
If a magnetic closure is added to the zipper, then the ease of operation is improved through automatic closing, but the device complexity increases
Solution Approach 1:
The closure system is segmented into two independent closures (zipper and magnetic) that can function separately. This modular segmentation allows the magnetic closure to be added without completely redesigning the existing zipper system, thereby improving ease of operation while limiting the increase in overall complexity
Solution Approach 2:
The magnetic closure components are arranged one behind the other in the access direction, with the magnetic closure facing the outside and the zipper facing the inside. This nested arrangement allows both closures to occupy similar spatial boundaries, minimizing the increase in device complexity while enabling automatic closing functionality
