Vehicle Input Device Push-Rotation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dial controllers for vehicles have a complex structure due to the integration of push and rotation operations, leading to increased manufacturing costs and design limitations, which fail to satisfy rapidly changing consumer demands and degrade user satisfaction.
Innovation Solution
An input apparatus with a simplified structure that performs push and rotation operations independently, using a push button device and a dial device that maintain separate postures during operations, with sensing devices to prevent erroneous interactions and improve stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an encoder switch is used to sense both push and rotation operations, then the sensing function is integrated, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent divides the sensing function into two separate sensing devices: a first sensing device for detecting push operations and a second sensing device for detecting rotation operations. This segmentation allows each sensing device to be optimized for its specific function, simplifying the overall structure while maintaining comprehensive sensing capability.
Solution Approach 2:
The patent combines the push button device and dial device into a single integrated input apparatus housing, allowing both push and rotation operations to be performed from the same physical interface while using separate sensing mechanisms for each operation type.
2Adaptability or versatility
If the entire dial controller is configured to be pressed or rotated, then both operations can be performed, but the design is limited and cannot satisfy changing consumer demands
Solution Approach 1:
The input apparatus is segmented into distinct functional zones: a push button device for pressing operations and a dial device for rotation operations. This segmentation enables independent optimization of each operation type and allows for greater design flexibility in shaping and positioning each component.
Solution Approach 2:
Different parts of the input apparatus have different functional properties: the push button device is designed to be pressed vertically, while the dial device is designed to be rotated horizontally. This local differentiation of function allows each component to be optimized for its specific operation while maintaining overall integration.
3Ease of operation
If a switch knob with symbol is mounted on the dial controller, then user guidance is provided, but the symbol rotates together with the dial, degrading user satisfaction
Solution Approach 1:
The symbol is separated from the rotating dial device and instead mounted on the stationary housing or a non-rotating component. This segmentation ensures that the symbol remains fixed and provides consistent user guidance while the dial device rotates independently for operation.
4Reliability
If push and rotation operations are performed independently with separate sensing devices, then erroneous operations are minimized, but the structure becomes more complex
Solution Approach 1:
Separate sensing devices are used for push and rotation operations to eliminate cross-interference and erroneous operation detection. The first sensing device exclusively detects push operations while the second sensing device exclusively detects rotation operations, ensuring high reliability for each function.

AI summary
An input apparatus for a vehicle includes: a housing mounted on the vehicle; a substrate disposed inside the housing; a push button device disposed in the housing to be pressed; a dial device arranged and configured to be rotated about the push button device, being non-peristaltic when the push button device is pressed, and maintained in a posture with respect to the housing, a first sensing device disposed on the substrate to sense pressing of the push button device; and a second sensing device disposed on the substrate to sense rotation of the dial device.
