Rotary Electronic Component Tactile and Auditory Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary electronic components provide only tactile clicking feedback, lacking additional methods to confirm operation state, which is a limitation in usability for product manufacturers seeking enhanced user interaction.
Innovation Solution
A rotary electronic component design that incorporates a rotor with radially formed grooves, a ring-shaped plate spring with inclined resilient arms and flat parts, and an upper member that restricts plate spring rotation, generating both tactile feedback and sound through the striking of flat parts against the upper member when resilient arms move over grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only tactile clicking feedback is provided in conventional rotary electronic components, then the structure remains simple, but the usability and operation state confirmation are insufficient
Solution Approach 1:
The plate spring serves multiple functions: it provides tactile clicking feedback through resilient arm deflection and simultaneously generates auditory feedback through sound generation. This multi-functionality resolves the contradiction by enhancing operation state confirmation without proportionally increasing device complexity
Solution Approach 2:
The invention introduces a new sensory dimension (acoustic feedback) analogous to color changes, where the plate spring generates sound during operation to provide additional operation state confirmation beyond tactile feedback alone
2Ease of operation
If the plate spring is allowed to rotate freely with the rotor, then the structure is simpler, but the sound generation mechanism cannot function properly
Solution Approach 1:
The plate spring is divided into functional segments: resilient arms that rotate with the rotor to provide tactile feedback, and flat parts that are retained stationary relative to the upper member to generate sound. This segmentation allows differential motion between parts, enabling sound generation while maintaining structural simplicity
Solution Approach 2:
The upper member acts as an intermediary between the rotating plate spring and the housing, providing a stationary surface for the flat parts to strike and generate sound, while allowing the resilient arms to rotate freely for tactile feedback
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides clear operation state feedback through both tactile and auditory cues, enhancing user experience by ensuring the user can understand the operation state via clicking feedback and sound generation simultaneously.
Implementation Method 1
The spring constant of the resilient arms and the shape of the flat part are set to achieved the state such that the resilient arms bend and at the same time the flat part is partially released from the bottom face of the upper member when the resilient arms move over the position between the adjacent grooves
Implementation Method 2
the flat part strikes the bottom face of the upper member. The user can thus readily understand the operation state due to both tactile feedback and sound

AI summary
In a rotary electronic component, the rotor includes a flange with the first face on which grooves are formed radially and the second face. The plate spring with a ring shape in the top view, includes resilient arms and flat parts. The upper member has the bottom face covering the plate spring and the first face, and retains the flat part such that the flat part can be attached to or detached from the bottom face of the upper member while preventing the plate spring from rotating responsive to rotation of the rotor. A spring constant of the resilient arms and the shape of the flat part are set to achieve the state such that the resilient, arms bend and the flat part is partially released from the bottom face of the upper member when the resilient arms go over a position between adjacent grooves.
