Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyboard is added for outdoor use, then typing functionality is improved, but the keyboard is easily eroded by dust and moisture
Solution Approach 1:
The patent combines the keyboard mechanism with the protective case structure, integrating the keyboard into the case body rather than using a separate external keyboard. This merging approach allows the keyboard to benefit from the case's protective enclosure while maintaining typing functionality, directly addressing the erosion problem by embedding the keyboard within the protective structure.
Solution Approach 2:
The protective case is designed to serve multiple functions: it protects the terminal unit, provides a built-in keyboard for typing, offers wireless charging capability, and includes a photovoltaic charging mechanism. This multi-functionality eliminates the need for separate accessories while providing comprehensive protection and operational capabilities in outdoor environments.
2Ease of operation
If the mobile terminal is held close for typing, then typing convenience is improved, but eye damage occurs due to prolonged close viewing
Solution Approach 1:
The patent incorporates a flexible connecting mechanism with adjustable angles between the keyboard portion and the terminal support portion. This dynamic structure allows the user to adjust the viewing and typing angle to a comfortable position, enabling the terminal to be held at a greater distance from the eyes while maintaining typing convenience, thus preventing eye strain and damage.
3Adaptability or versatility
If outdoor activities are performed, then mobility is improved, but power depletion occurs due to lack of charging infrastructure
Solution Approach 1:
The patent integrates a photovoltaic charging mechanism into the protective case, enabling the device to charge itself using solar energy during outdoor activities. This preliminary action of capturing solar energy allows the device to replenish its power supply proactively while being used outdoors, eliminating the need for external charging infrastructure and reducing power depletion concerns.
4Adaptability or versatility
If multiple accessories are carried for outdoor use, then functionality is improved, but device complexity and portability are reduced
Solution Approach 1:
The patent merges multiple previously separate accessories into a single integrated protective case structure. The keyboard mechanism, wireless charging mechanism, photovoltaic charging mechanism, and terminal support structure are all combined into one unified device, eliminating the need to carry separate keyboards, chargers, and protective cases, thus reducing complexity while maintaining full outdoor functionality.
