Protective Slider Zipper with Bending Structure for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic packing bags with slider zippers often fail to close properly due to residues, leading to poor air-tightness and increased risk of moisture exposure, which can cause food spoilage and pose safety hazards, especially for children accessing toxic products.
Innovation Solution
A protective slider zipper design featuring a bending or rotating structure with support surfaces and slider hands that prevent loosening, includes ailerons for dust prevention and a reinforcing rib, allowing easy adult operation while being challenging for children, and a second slider hand for residue clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional slider zipper is used without protective structure, then the zipper can be easily opened and closed, but residues block the closure and children can access toxic products
Solution Approach 1:
The protection structure is designed to be dynamically changeable between a protected state (covering the zipper) and a working state (allowing operation). The bending structure enables the protection structure to transition between these states, providing child safety while maintaining adult accessibility and reliable closure functionality.
Solution Approach 2:
The slider is divided into distinct functional segments: the protection structure for safety, the bending structure for state transition, the ailerons for residue management, and the slider body for zipper operation. This segmentation allows each component to perform its specific function independently while working together as an integrated system.
2Reliability
If the zipper is equipped with only basic closure function, then the structure is simple, but air-tightness is poor and goods are exposed to moisture and pollution
Solution Approach 1:
The ailerons are designed as movable flaps that dynamically adjust based on zipper closure status. When the zipper is properly closed, the ailerons cover the opening to enhance air-tightness; when opened, they move aside to allow access. This dynamic adaptation provides improved sealing without requiring a completely complex rigid structure.
3Object-affected harmful factors
If no protection structure is provided, then the device is easy to operate, but children can easily open it and access toxic products
Solution Approach 1:
The protection structure utilizes a bending mechanism that requires deliberate adult action to transition from protected to working state. The structure is designed to remain in the protected state under normal conditions (preventing child access) but can be easily transitioned to the working state by adults who need to open or close the zipper, thus balancing safety with operational convenience.
4Reliability
If residues are present on the zipper, then the zipper cannot be properly closed, but adding cleaning mechanisms increases complexity
Solution Approach 1:
The ailerons are designed to move dynamically during the zipper closure process. As the slider moves along the zipper, the ailerons sweep across the tooth surfaces, automatically clearing residues in the direction of closure. This dynamic cleaning action is integrated into the existing closure motion, providing residue removal without requiring separate cleaning mechanisms.
