Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific capacitive screen stylus is used for a predetermined capacitive screen, then the interaction with the screen is reliable, but the cost increases and versatility decreases
Solution Approach 1:
The manual device body is designed with a standardized bayonet connection interface that can accommodate multiple different end pieces (eraser, stylus tip, brush, etc.), allowing a single body to perform multiple functions across different capacitive screen applications, thereby achieving versatility without sacrificing interaction reliability through the standardized electrical contact interface
2Reliability
If a specific capacitive screen stylus is used for a predetermined capacitive screen, then the interaction with the screen is reliable, but the cost increases
Solution Approach 1:
The stylus is divided into two separable parts: a reusable body and interchangeable end pieces. This segmentation allows the expensive body (containing the electrical contact and connection mechanism) to be used multiple times with different end pieces, reducing the overall cost per use while maintaining reliable electrical contact through the standardized bayonet connection interface
3Ease of operation
If a removable end piece is assembled by bayonet connection, then the ease of assembly and disassembly is improved, but the device complexity increases
Solution Approach 1:
The complex electrical contact and connection mechanism is extracted into a standardized bayonet connection interface that is integrated into the body. This allows the end pieces to be simple, inexpensive components that can be easily assembled and disassembled by the user, while the complexity is confined to the reusable body, achieving ease of operation without excessive overall device complexity
