Detachable Corner Protection for Case Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cases, such as trunks and tool boxes, are prone to corner deformation or cracking during transportation due to collisions, leading to structural damage and reduced durability, with no effective means to protect the corners and resulting in resource wastage when corner damage occurs.
Innovation Solution
A case with detachable corner-protection members featuring an engaging post and elastic segments, which are assembled into grooves and holes, providing impact protection and allowing for easy replacement of damaged components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the case is integrally formed, then the structure is simple and manufacturing is easy, but the corners cannot be protected independently and the entire case must be discarded when corners are damaged
Solution Approach 1:
The case is divided into two independent parts: the main case body and separate corner-protection members. The corner-protection members can be independently replaced when damaged, while the main case body remains usable. This segmentation resolves the contradiction by allowing easy manufacturing of the case body while enabling independent corner replacement.
Solution Approach 2:
When corners are damaged, only the corner-protection members are discarded and replaced, while the main case body is recovered and continues to be used. This principle resolves the contradiction by minimizing waste and maintaining the value of the main case structure.
2Stability of the object's composition
If the case is integrally formed, then the structural integrity is good, but the corners are vulnerable to collision damage and durability is reduced
Solution Approach 1:
The corner-protection members provide enhanced protection specifically at the vulnerable corner locations, while the main case body maintains its original structural integrity. This local quality enhancement resolves the contradiction by strengthening only where needed without compromising the overall structure.
Solution Approach 2:
The corner-protection members are pre-installed on the case corners before use, providing advance protection against collision damage. This beforehand cushioning resolves the contradiction by preventing corner damage before it occurs while maintaining the case's structural integrity.
3Reliability
If corner-protection members are added to protect the corners, then the durability and protection capability are improved, but the device complexity increases
Solution Approach 1:
The corner-protection members are designed to be detachable and replaceable, transforming the static case structure into a dynamic system where protective elements can be added or removed as needed. This dynamics principle resolves the contradiction by providing protection capability while maintaining assembly flexibility and reducing permanent complexity.
Solution Approach 2:
The protection system is segmented into separate corner-protection members that can be independently assembled onto the case. This segmentation resolves the contradiction by distributing the protection function across multiple simple components rather than requiring a single complex integrated structure.
4Reliability
If the corners are damaged, then the case functionality is compromised, but discarding the entire case causes resource waste and economic burden
Solution Approach 1:
When corners are damaged, only the corner-protection members are discarded and replaced, while the main case body is recovered and continues to be used. This principle directly resolves the contradiction by minimizing resource waste and eliminating the economic burden of discarding a functional case.
Solution Approach 2:
The damage is localized to the corner-protection members, which can be replaced independently. This local quality approach resolves the contradiction by maintaining the functionality of the main case while replacing only the damaged protective elements, thereby reducing resource waste.

AI summary
A case with a corner-protection structure includes: the case has at least one assembling portion located at a corner, the assembling portion includes: an outer surface, an inner surface opposite to the outer surface, an assembling hole extending through the outer surface and the inner surface, and two assembling grooves formed in the outer surface and disposed at opposite sides of the assembling portion; and a corner-protection member detachably assembled on the assembling portion of the case, the corner-protection member includes: an abutting surface abutted against the outer surface, two engaging portions disposed on the abutting surface and slidably disposed in the two assembling grooves, and an engaging post disposed on the abutting surface and inserted in the assembling hole. The corner-protection structure is capable of protecting the fragile corners of the case, and effectively reducing the problem that the corners are easily damaged by collision.
