Wire Mobile Device Case With Tensioned Corner Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device cases are often bulky and undesirable due to their increased size and weight, failing to provide effective protection while maintaining a minimal and stylish design.
Innovation Solution
A wire device case featuring corner pieces with channels and a tensioner system, where a wire passes through the channels and is tensioned by the tensioner to create an inward force, securing the corner pieces to the device, thereby providing protection without bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cases are used to protect mobile devices, then protection effectiveness is improved, but device size and weight increase
Solution Approach 1:
The case is segmented into four separate corner pieces rather than a single enclosing shell. Each corner piece independently protects one corner of the device, providing focused protection where impacts most commonly occur while minimizing overall material usage and weight.
Solution Approach 2:
The protective function is extracted from a traditional full-enclosure case and concentrated only at the four corners. This selective approach removes unnecessary material from areas that don't require protection, significantly reducing case weight and size while maintaining effective protection at critical impact zones.
2Strength
If conventional cases are used to protect mobile devices, then protection effectiveness is improved, but device bulkiness increases
Solution Approach 1:
The case is divided into four discrete corner pieces that attach only at the device corners. This segmentation eliminates the need for a bulky continuous enclosure, reducing overall case volume while maintaining protection effectiveness at the most vulnerable points.
Solution Approach 2:
Protection is applied locally at the four corners where impact damage is most likely to occur, rather than uniformly across the entire device. This localized approach minimizes case volume by concentrating protective material only where needed, avoiding unnecessary bulk in areas that don't require protection.
3Reliability
If corner pieces are secured with sufficient tension to ensure protection, then reliability is improved, but device complexity increases
Solution Approach 1:
Four separate tensioning operations are merged into a single wire system that passes through all four corner pieces. The wire is tensioned once at one location, and this single tensioning action simultaneously secures all four corner pieces to the device, simplifying the overall structure and reducing the number of moving parts.
Solution Approach 2:
The single wire serves multiple functions: it passes through all four corner pieces, provides tension to each corner, and acts as a retention mechanism for the entire case system. This multi-functional element reduces structural complexity compared to having separate fastening mechanisms for each corner.
