Storage Box Lid Fixation Using Internal Elastic Tension Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage boxes with covers face issues of increased production costs due to movable fastening means that degrade over time, leading to structural integrity loss and making the boxes unusable with defects, and require coordinated shape designs for support areas.
Innovation Solution
A storage box design utilizing elastic tensioning elements guided through recesses in the side walls, providing internal and external support for the cover, allowing secure attachment without separate movable parts, and enabling easy reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If movable fastening means are used to attach the cover, then the cover can be opened and closed, but the material becomes brittle after repeated use and loses structural integrity
Solution Approach 1:
The patent extracts the movable fastening means from the storage box structure and replaces it with a static elastic tensioning element that runs through recesses in the side walls. The elastic element provides continuous tension to hold the cover without requiring mechanical joints that degrade with movement, thereby maintaining structural integrity while enabling repeated opening and closing operations.
2Reliability
If separate fastening parts are used, then the cover can be secured to the box, but production costs increase
Solution Approach 1:
The patent merges the fastening function and the support area function into a single integrated elastic tensioning element. This eliminates the need for separate movable fastening parts and reduces the number of components, thereby lowering production costs while maintaining reliable cover attachment through the continuous tension provided by the elastic element.
Solution Approach 2:
The elastic tensioning element serves multiple functions simultaneously: it provides the fastening force to secure the cover, creates the support area for the cover through its guided path in the recesses, and maintains structural integrity without requiring additional separate parts. This multi-functionality reduces overall production costs.
3Stability of the object's composition
If special shape designs are used in edge areas to create support areas, then the cover can be supported, but the shape coordination between support area and cover becomes complex
Solution Approach 1:
The patent segments the elastic tensioning element into sections that are guided through recesses in the side walls, with portions extending inside and outside the storage box. This segmentation allows the support area to be created through the spatial arrangement of the elastic element rather than through complex molded shapes, simplifying the design while maintaining stable cover support.
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 elastic tensioning elements ensure a secure, cost-effective, and durable attachment of the cover, maintaining structural integrity and simplifying production by eliminating the need for complex shape designs and movable parts.
Implementation Method 1
the fastening device has at least one elastic tensioning element, that the cover can be fixed relative to the storage box by means of the tensioning element
