Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices are prone to damage, particularly in the corners, which can transfer mechanical shock and require protection without increasing bulk or weight, and must allow easy access to input/output components.
Innovation Solution
An adjustable multi-component sheath made of stretchable materials like rubber or polymer, providing protection primarily in high-risk areas with adjustable interlock mechanisms for expansion and minimal thickness, ensuring access to buttons and jacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is added to protect corners and screen, then protection against shock and damage is improved, but the bulk and weight of the device increase
Solution Approach 1:
The protective cover is divided into multiple independent components: a front piece for screen protection, a back piece for rear protection, and corner pieces for high-risk area protection. These segmented components are connected through flexible linkages, allowing each piece to provide protection only where needed rather than requiring a complete enclosing case, thus reducing overall weight while maintaining protection effectiveness.
Solution Approach 2:
The invention applies protection selectively to high-risk areas (corners and screen) rather than uniformly across the entire device. The corner pieces are specifically designed to protect the most vulnerable points, while the flexible linkages allow the protective structure to adapt to different device shapes and sizes, providing localized protection without adding unnecessary bulk or weight to areas that don't require it.
2Reliability
If a protective cover is added to protect corners and screen, then protection against shock and damage is improved, but the bulk of the device increases
Solution Approach 1:
The protective cover is divided into multiple independent components: a front piece for screen protection, a back piece for rear protection, and corner pieces for high-risk area protection. These segmented components are connected through flexible linkages, allowing each piece to provide protection only where needed rather than requiring a complete enclosing case, thus reducing overall bulk while maintaining protection effectiveness.
Solution Approach 2:
The protective cover incorporates flexible linkages that allow the structure to dynamically adapt to different device shapes, sizes, and orientations. This dynamic flexibility enables the protective components to move independently, providing protection when needed while collapsing or conforming to the device profile when not in use, thereby minimizing added bulk.
3Ease of operation
If the protective cover is made slim and minimalist, then portability and handheld comfort are improved, but protection capability in high-risk areas is reduced
Solution Approach 1:
The invention applies protection selectively to high-risk areas (corners and screen) rather than uniformly across the entire device. The corner pieces are specifically designed to protect the most vulnerable points, while the flexible linkages allow the protective structure to adapt to different device shapes and sizes, providing localized protection without adding unnecessary bulk or weight to areas that don't require it.
Solution Approach 2:
The protective cover utilizes composite construction with rigid protective pieces (for impact resistance) connected through flexible linkages (for adaptability and slim profile). This composite approach combines the strength of rigid materials where protection is needed with the flexibility of softer materials in connecting elements, achieving both protection capability and slim minimalist design.
4Reliability
If the protective cover is designed to fit specific device models, then protection effectiveness is improved, but versatility across different device models is reduced
Solution Approach 1:
The protective cover incorporates flexible linkages that allow the structure to dynamically adapt to different device shapes, sizes, and orientations. This dynamic flexibility enables the protective components to move independently, providing protection when needed while collapsing or conforming to the device profile when not in use, thereby minimizing added bulk.
Solution Approach 2:
The protective cover is designed with universal compatibility across multiple device models through its modular segmented structure and flexible linkages. The same basic design can accommodate different screen sizes, device thicknesses, and shapes by adjusting the flexibility and configuration of the linkages, allowing a single protective cover design to serve multiple device models effectively.

AI summary
A multi-component sheath to protect portable electronics devices. The device provides coarse adjustment in height-direction or y-direction. A region enabling connection between the upper piece and lower piece allowing significant extension of the mechanism along the longest axis of the portable electronic device. An additional fine adjustment in both height-direction or y-direction and width or y-direction is also possible. Minor expansion of the pieces in the longitudinal and transverse directions of the portable electronic device, due to intrinsic elongation and stretch characteristics of the sheath material (e.g. polymer or rubber). The device provides minimalist coverage of the portable electronic device on the back and sides. The present invention provides protection mostly in the corners. The present invention results in a minimal increase in overall thickness of the portable electronic device, less than 2 mm. The device allows full access to all input/output connections and buttons of the device.
