Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensing component is added to expand functionality, then the device capabilities are improved, but the device complexity increases
Solution Approach 1:
The sensing component is integrated into the pivot mechanism, merging the sensing function with the existing mechanical structure. The sensing substrate is disposed within the pivot assembly, combining multiple functions (rotation mechanism + sensing input) into a single integrated component, thereby expanding functionality without proportionally increasing overall device complexity
Solution Approach 2:
The pivot structure serves multiple functions: it enables rotation between folded and unfolded states, and simultaneously houses the sensing component for user input operations. This multi-functionality allows the device to achieve enhanced adaptability while maintaining a compact and efficient mechanism configuration
2Ease of operation
If the sensing component is placed on the back surface for easy operation, then the ease of operation is improved, but the area available for other components is reduced
Solution Approach 1:
The sensing component utilizes the vertical dimension and angular orientation rather than occupying horizontal back surface area. The sensing substrate is positioned at an acute angle to the back surface, allowing finger interaction in a three-dimensional space above the back surface while minimizing the footprint on the back surface itself
3Ease of operation
If the sensing substrate is positioned at an acute angle for operation, then the ease of operation is improved, but the structural stability is reduced
Solution Approach 1:
The sensing substrate is designed to dynamically adjust its position and angle as the pivot rotates between folded and unfolded states. The sensing component's orientation changes with the pivot angle, maintaining optimal accessibility during operation while being structurally supported by the robust pivot mechanism that ensures stable positioning at each state

AI summary
A foldable electronic device includes a first body, a second body, a pivot, and a sensing component. The pivot is pivotally connected between the first body and the second body. The first body and the second body are configured to rotate relative to each other through the pivot, and the pivot includes a driving element. The sensing component is coupled to the pivot and the second body, and includes a sensing substrate and an interfering element connecting the sensing substrate. The driving element structurally interferes with the interfering element while rotating along with the pivot, so as to drive the interfering element to rotate, such that the sensing substrate rotates between an initial position where the sensing substrate leans on a back surface of the second body, and an operating position where an acute angle is formed between the sensing substrate and the back surface of the second body.
