Bag Closure Profile Members Resonance Amplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing devices for bags lack sufficient tactile sensation and sound effect during engagement and separation, with prior methods providing limited tactile and acoustic feedback.
Innovation Solution
The use of two complementary profile member assemblies with multiple closure elements featuring sequential crushings and support mats, where the support mats are integrally formed and wider than the attachment elements, creating a resonance phenomenon that amplifies the tactile and sound effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If periodic deformation or cutout is created along one of the two profile members, then tactile and acoustic effect is generated, but the effect remains limited
Solution Approach 1:
The profile members are divided into multiple discrete attachment elements (at least two per member) with sequential crushings distributed along their length. This segmentation creates multiple localized deformation points that generate enhanced tactile feedback and acoustic effects compared to a single continuous deformation pattern.
Solution Approach 2:
The support mat is designed to propagate vibratory mode during engagement and separation of profile members. The mat's dimensions and material properties are optimized to amplify mechanical vibrations generated by the sequential crushings, transforming limited local effects into pronounced tactile and acoustic feedback.
2Ease of manufacture
If multiple profiled attachment elements with sequential crushings are used, then tactile sensation and sound effect are enhanced, but device complexity increases
Solution Approach 1:
The profiled attachment elements and support mat are integrally formed as a single piece, eliminating the need for separate assembly steps. This merging reduces manufacturing complexity despite the presence of multiple attachment elements with sequential crushings, as the entire structure is created in one forming operation.
Solution Approach 2:
The support mat serves multiple functions: it provides structural support for the profiled attachment elements, propagates vibratory mode for acoustic amplification, and acts as the base structure for integral forming. This multi-functionality reduces the need for additional components, offsetting the complexity introduced by multiple attachment elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly enhances the tactile and sound effects by initiating a resonance phenomenon at the attachment elements, leading to a more pronounced amplification effect compared to prior art, resulting in a more engaging and audible closure experience.
Implementation Method 1
The Applicant has determined that the very specific triple combination in conformity with the present invention including 1) multiplication of the closure members, 2) sequential crushings and 3) the support mat integrally formed with the attachment elements, generates an improved effect compared with the prior art, thanks to a resonance phenomenon initiated at the attachment elements and propagated in vibratory mode at the support mat, leading to an amplification effect.
