Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional jog dials are used for menu navigation, then the control mechanism is simple, but the ease of operation deteriorates due to increased menu complexity and information overload
Solution Approach 1:
The control element is segmented into multiple functional components: a rotatable second housing part for navigation, a finger element for position indication, and multiple key elements for different selection functions. This segmentation allows each component to handle specific control tasks, making the overall system more manageable and easier to operate despite increased menu complexity.
Solution Approach 2:
The control element combines multiple functions into a single integrated device: rotation for navigation, finger element positioning for selection indication, and multiple key elements for different confirmation/actions. This multi-functionality reduces the need for separate controls and simplifies the user interface despite handling complex menus.
2Adaptability or versatility
If multiple control elements are used to handle increased menu complexity, then the functionality improves, but the device complexity increases
Solution Approach 1:
Multiple control functions are merged into a single control element: the rotatable housing combines navigation functions, the finger element combines position indication, and multiple key elements are integrated into one housing. This merging maintains versatility while reducing the number of separate control elements needed.
Solution Approach 2:
The control element is designed as a universal control device that can handle various menu navigation tasks, selection operations, and confirmation actions through its integrated components, replacing the need for multiple specialized control elements.
3Measurement precision
If electronic components are used in the control element, then the detection precision improves, but the manufacturing cost increases
Solution Approach 1:
The control element uses passive electrical and magnetic materials that are detected by the display unit's existing sensor system. The control element itself does not require active electronic components or power sources, as it leverages the display unit's detection capabilities to identify its position, rotation state, and key element actuation.
Solution Approach 2:
Traditional active electronic sensors and power sources are replaced with passive mechanical and magnetic elements. The control element uses electrical conductive and magnetic materials that passively interact with the display unit's detection system, eliminating the need for batteries, circuits, or active electronics within the control element itself.
4Measurement precision
If the control element requires power sources, then the detection accuracy improves, but the reliability deteriorates due to potential power failures
Solution Approach 1:
The control element is designed to be powered by the display unit itself through its detection system. The passive electrical and magnetic materials in the control element are detected by the display unit's sensors, eliminating the need for separate power sources and improving reliability by removing battery failure risks.
