Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bar type mobile phones are particularly vulnerable to damage from drops and impacts due to their design, necessitating a protective case with an effective shock absorbing structure.
Innovation Solution
A mobile phone case with a shock absorbing structure comprising a protective shell, a side enclosure frame, and shock absorbing blocks with recesses and ledges that distribute impact across the case, utilizing soft materials for absorption and hard materials for compression, along with a groove pattern to prevent slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective case is designed to cover the entire electronic device, then protection coverage is improved, but the front portion of the device becomes significantly covered and functionality is reduced
Solution Approach 1:
The protective case applies different levels of protection to different areas of the device. Shock absorbing blocks are strategically placed at corners and edges where impact is most likely to occur, while the front portion maintains minimal coverage to preserve accessibility and functionality. This localized approach to protection resolves the contradiction between comprehensive protection and operational ease.
2Strength
If a solid block structure is used for shock absorption, then impact resistance is improved, but the case becomes heavier and less adaptable to different device sizes
Solution Approach 1:
The shock absorbing structure is divided into multiple separate blocks rather than using a single solid structure. These individual shock absorbing blocks are positioned at specific high-impact areas (corners and edges), reducing overall material usage and weight while maintaining effective impact resistance where needed most.
Solution Approach 2:
The case design allows the shock absorbing blocks to be adjusted or removed based on specific device requirements and usage scenarios. This adaptability enables optimization of the weight-strength balance for different electronic device sizes and protection needs.
3Reliability
If multiple shock absorbing blocks are added to enhance protection, then shock absorption capability is improved, but the case structure becomes more complex and harder to manufacture
Solution Approach 1:
The case is designed as an assembly of modular components including the main body and separate shock absorbing blocks. This segmentation allows each component to be manufactured independently using standard processes, then assembled together, reducing overall manufacturing complexity while achieving enhanced shock absorption through the combination of multiple protective elements.

AI summary
The present invention relates to a case having a shock absorbing structure for an electronic device which includes a protective shell, a side enclosure frame, and a shock absorbing block. The shock absorbing block is constructed to have a plurality of recesses formed on the side wall of the protective shell such that adjacent recesses are separated by a partition. The recesses are rectangular and the plurality of recesses has a continuous unitary construction along lower part of the four sides of the protective shell. In addition, the side enclosure frame includes an upper protrusion and a lower protrusion, formed on an inner-facing surface of the side enclosure frame. The side wall of the protective shell includes an upper cavity and a lower cavity. The upper protrusion fits within the upper cavity and the lower Protrusion fits within the lower cavity.
