Innovation Solution
A multi-functional waterproof protective sleeve comprising a face cover, middle frame, and rear cover with integrated solar charging, wireless charging, and portable power modules, along with a control mainboard for charging priority modes, and features like fingerprint recognition flexible film, camera lens, and soft rubber stoppers for all-dimensional waterproofing and improved endurance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof protective sleeve is used for mobile terminal, then waterproof function is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple protective functions (waterproofing, charging, power storage) into a single integrated protective sleeve structure. The sleeve incorporates solar charging modules, wireless charging coils, and portable power batteries directly into its construction, eliminating the need for separate waterproof cases and external charging devices, thus reducing overall system complexity while maintaining comprehensive protection.
Solution Approach 2:
The protective sleeve is designed to perform multiple functions simultaneously: it provides waterproof protection, enables solar charging, supports wireless charging, and offers portable power supply. This multi-functional design eliminates the need for multiple separate devices, reducing the complexity of having to manage multiple accessories while ensuring comprehensive protection and charging capabilities.
2Duration of action of moving object
If charging modules are integrated into waterproof sleeve, then endurance ability is improved, but device complexity increases
Solution Approach 1:
The patent integrates three different charging systems (solar charging module with photovoltaic cells, wireless charging module with coils, and portable power battery) into a single protective sleeve. The control mainboard统一管理 these charging systems, allowing the mobile terminal to be charged through multiple pathways without requiring separate charging devices, thus extending endurance while managing complexity through centralized control.
Solution Approach 2:
The protective sleeve incorporates multiple charging modalities (solar, wireless, and portable power) to provide universal charging capability across different scenarios. This allows the mobile terminal to maintain operation for extended periods regardless of environmental conditions, improving endurance by providing multiple charging options within a single integrated system.
3Manufacturing precision
If in-mold cover injection molding process is used, then manufacturing precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent uses in-mold cover injection molding to integrate multiple components (sealing rings, charging modules, structural elements) into a single molded piece. This process combines several manufacturing steps into one operation, achieving high sealing precision and component integration while actually simplifying the overall manufacturing process by reducing the number of assembly steps and quality control checkpoints.
