Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knob structures are limited in design flexibility due to reliance on pressing and rotating operations, which restrict product innovation.
Innovation Solution
A knob structure that includes a conductive pad, conductive member, operating cover, and conductive film, allowing signal transmission through a grasping operation by coupling the conductive film to the conductive pad via the conductive member, enabling control of a touch function display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional knob structures use only pressing and rotating operations, then the operation method is simple and reliable, but the design flexibility and functionality are limited
Solution Approach 1:
The operating cover is designed to perform multiple functions: it can be pressed to trigger pressing operations, rotated to trigger rotating operations, and gripped to trigger grasping operations. This multi-functional design allows a single component to replace what would traditionally require multiple separate controls, thereby improving adaptability without proportionally increasing device complexity
Solution Approach 2:
The conductive film acts as an intermediary between the operating cover and the conductive pad. When the operating cover is gripped, the conductive film transfers the trigger charge to the conductive pad through the conductive member, enabling signal transmission without direct contact between the operating cover and the conductive pad. This intermediary mechanism enables new operation modes while maintaining structural simplicity
2Adaptability or versatility
If the knob structure adds grasping operation capability, then the functionality and design flexibility are enhanced, but the structural complexity increases
Solution Approach 1:
The conductive member is integrated into the operating cover structure, with its first end portion abutted against the seat and electrically coupled to the conductive pad, and its second end portion abutted against the conductive film on the inner edge of the operating cover. This merging of components allows the grasping operation capability to be added without significantly increasing overall structural complexity
Solution Approach 2:
The conductive film is disposed on the inner edge of the operating cover, providing a flexible conductive path that can accommodate the grasping operation. This thin film approach adds minimal structural complexity while enabling the new operation mode through the transfer of trigger charge from the operating cover to the conductive pad
