Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a separate display screen is equipped for each function, then the display area and interaction capability are improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple display functions into a single dual-sided display structure. The front display and back display are integrated into one display module that can be controlled by a shared control circuit, reducing the number of separate display components while maintaining large display area for complex functions.
Solution Approach 2:
The dual-sided display serves multiple functions: the front display provides primary interaction, while the back display can show notifications, health data, or serve as a secondary interaction interface. This multi-functional design eliminates the need for separate dedicated displays for each function.
2Device complexity
If a single display is used, then the device complexity is reduced, but the display area and interaction capability are insufficient
Solution Approach 1:
The patent transitions from a single-sided display to a dual-sided display configuration. By utilizing both the front and back surfaces of the display module, the total display area is effectively doubled without proportionally increasing device complexity, as both displays share common control circuits and structural support.
3Ease of manufacture
If the smart watch has a fixed appearance design, then the manufacturing process is simplified, but the esthetic versatility is limited
Solution Approach 1:
The patent employs asymmetric design where the front and back of the smart watch have different appearances optimized for different purposes. The front features a primary display for main interactions, while the back has a secondary display with different design characteristics, allowing each side to be aesthetically optimized without complicating the overall manufacturing process.
Solution Approach 2:
The smart watch design allows dynamic configuration where the front and back displays can be independently customized with different sizes, shapes, and content. This dynamic adaptability enables versatile aesthetic options while maintaining a unified manufacturing platform through modular display components.
