Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stylus pen is fixed outside or inserted into the casing of the electronic device, then the stylus pen can be stored, but it is difficult to access and charge, making it easy to be lost
Solution Approach 1:
The charging function is segmented from the main body of the stylus pen and integrated into a separate charging base. The charging base includes a receiving cavity that can accommodate the stylus pen, with charging pins that extend to contact the conductive structures on the stylus pen. This segmentation allows the stylus pen to be easily accessed and charged independently from the electronic device casing.
Solution Approach 2:
The charging base acts as an intermediary device between the stylus pen and the power source. It includes a receiving cavity with conductive structures (charging pins) that contact the stylus pen's conductive structures (first and second conductive structures) to transfer electrical energy. This intermediary solution resolves the contradiction by providing dedicated charging functionality without requiring the stylus pen to be inserted into the electronic device casing.
2Adaptability or versatility
If the stylus pen is designed with a single charging orientation, then the charging structure is simple, but it cannot match different use states
Solution Approach 1:
The charging base is designed with universal charging capability that can accommodate the stylus pen in multiple orientations (upright or horizontal insertion). The receiving cavity includes a first conductive structure and a second conductive structure that can contact the stylus pen's conductive structures regardless of the insertion orientation. This multi-functional design allows the same charging structure to handle different use states without increasing complexity significantly.
Solution Approach 2:
The charging base utilizes spatial arrangement of conductive structures to enable multi-orientation charging. The first and second conductive structures are positioned at different locations and angles within the receiving cavity, allowing the stylus pen to be charged whether inserted upright or horizontally. This dimensional arrangement provides charging flexibility without requiring multiple separate charging mechanisms.
