Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel operating apparatuses are unable to simultaneously detect both rotating and pressing operations effectively, often requiring increased size or lacking a hole for display or illumination, and existing solutions either cannot detect pressing operations or are cumbersome in design.
Innovation Solution
An operating apparatus with a ring-shaped operation body featuring a circular hole, incorporating a press detection conductor and a rotation detecting conductor arranged around the hole, allowing for both pressing and rotating operations while maintaining a compact design and enabling the use of the hole for display or illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pressure detecting mechanism is added to the input apparatus of Japanese Patent No. 6632787, then both rotating and pressing operations can be detected, but the size of the operation body increases
Solution Approach 1:
The patent combines the pressing detection function and rotating detection function into a single integrated operation body structure. The conductive connector with multiple conductive terminals serves both detection purposes simultaneously, eliminating the need for separate detection mechanisms and maintaining a compact size while achieving versatile detection capability.
Solution Approach 2:
The operation body is designed as a multi-functional component that can detect both pressing operations and rotating operations using the same structural elements. The conductive connector supports multiple conductive terminals with different diameters that work together to detect different types of user interactions, making the operation body universally capable of handling various input modes.
2Adaptability or versatility
If the grasping portion has no hole, then the structure is simple, but it is impossible to use a hole as a display area or an illumination area
Solution Approach 1:
The operation body is segmented into functional zones: the main body structure for detection and the hollow interior space for display or illumination components. This segmentation allows the hole to serve as a functional display area while the surrounding structure maintains its detection capabilities, separating conflicting functional requirements into distinct spatial zones.
3Adaptability or versatility
If existing touch panel operating apparatuses are used, then the design is simple, but they cannot simultaneously detect both rotating and pressing operations effectively
Solution Approach 1:
The conductive connector acts as an intermediary element that translates both pressing and rotating operations into detectable electrical signals. By using the conductive terminals as mediators between the user's physical interactions and the detection system, the apparatus can detect multiple operation types without requiring complex separate detection mechanisms for each operation type.
