Elastic Fastening Portions for Secure Box Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing box designs suffer from lid and shell body separation issues, leading to food overflow and difficulty in securing the lid and shell body due to inadequate fastening mechanisms that are prone to loosening.
Innovation Solution
A combined box device featuring a lid and shell body with strategically positioned fastening portions and buckle slots, utilizing multiple contact surfaces and elastic materials to create a secure hook-and-contact mechanism, ensuring the lid and shell body fit tightly and remain securely closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening members are used, then the lid and shell body can be connected, but the fastening members are easy to loosen and difficult to hold together
Solution Approach 1:
The fastening portion is designed with elastic deformation capability, allowing it to dynamically adapt during the hooking process. The elastic material deforms to accommodate the buckles and then maintains continuous contact pressure, ensuring reliable fastening without requiring complex locking mechanisms.
Solution Approach 2:
The patent changes the physical state of the fastening portion by using elastic materials that can deform and recover. This parameter change allows the fastening members to transition from a rigid, hard-to-hook state to a flexible, easy-to-hook state, while maintaining secure connection.
2Reliability
If the opening edge of the lid and shell body are not designed with proper fastening structures, then the box structure remains simple, but the lid and shell body are not easy to adhere closely causing food overflow
Solution Approach 1:
The fastening system is segmented into multiple contact surfaces and multiple buckles distributed along the opening edge. This segmentation allows the closure tightness to be improved at multiple points simultaneously, preventing food overflow without requiring a single complex fastening mechanism.
Solution Approach 2:
The patent applies fastening portions with multiple contact surfaces at specific locations along the opening edge where they are most needed for sealing. This local quality approach ensures tight closure at critical areas while keeping the overall structure relatively simple.
3Reliability
If fastening portions with insufficient contact surfaces are used, then the fastening structure remains simple, but the hooking and buckling is not secure and easy to loosen
Solution Approach 1:
The fastening portion transitions from a one-dimensional linear contact to a two-dimensional multi-surface contact system. The multiple contact surfaces create a broader engagement area with the buckles, significantly improving fastening security without adding excessive structural complexity.
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 effectively prevents food overflow by ensuring a secure closure of the box, with the elastic materials allowing for easy hooking and retention of the fastening portions within the buckle slots, preventing the structure from loosening.
