Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button structures do not allow users to easily adjust the tactile feedback experienced when pressing the button, limiting the ability to enhance user experience and market competitiveness.
Innovation Solution
A button structure incorporating an adjustable limiting member that protrudes toward the elastic portion, allowing the length to be adjusted, thereby limiting the deformation of the elastic portion and changing the tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the button structure uses a fixed elastic portion without adjustment mechanism, then the structure is simple and easy to manufacture, but the tactile feedback cannot be customized or adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the limiting member adjustable rather than fixed. The limiting member can be positioned at different locations along the elastic portion, allowing the button's tactile feedback characteristics to be dynamically changed. This enables the same button structure to provide different tactile experiences by simply repositioning the limiting member, thus achieving adaptability without requiring multiple different button designs.
Solution Approach 2:
The patent implements parameter changes by allowing the position of the limiting member to be varied. By changing the position parameter of the limiting member along the elastic portion, the deformation characteristics of the elastic portion are modified, which directly changes the tactile feedback parameter of the button. This enables customization of tactile feedback through a single parameter adjustment rather than redesigning the entire button structure.
2Ease of operation
If the button structure allows easy adjustment of tactile feedback, then user experience and market competitiveness are enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the button structure into distinct functional components: the elastic portion, the limiting member, and the button head. The limiting member is designed as a separate, independently adjustable component that can be positioned and secured at different locations. This segmentation allows for easy adjustment of tactile feedback by simply repositioning the limiting member without affecting other components, while maintaining relatively simple manufacturing of each individual component.
3Stability of the object's composition
If the limiting member protrudes longer toward the elastic portion, then the deformation of the elastic portion is more restricted, but the tactile feedback becomes less responsive
Solution Approach 1:
The patent applies dynamics by making the limiting member's position adjustable rather than fixed. Users can dynamically adjust the position of the limiting member to find the optimal balance between deformation control and responsiveness. By moving the limiting member closer to the button head, responsiveness is improved; by moving it farther away, deformation control is enhanced. This dynamic adjustability allows the system to adapt to different operational requirements.
Solution Approach 2:
The patent implements parameter changes by allowing the position parameter of the limiting member to be varied. By changing this position parameter, users can control the degree of deformation restriction. When higher responsiveness is needed, the limiting member is positioned to allow greater deformation; when more stability is needed, it is positioned to restrict deformation more. This parameter adjustment enables fine-tuning of the balance between stability and responsiveness.

AI summary
A button structure includes a switch, a shell, an elastic member, a button and at least one adjustable limiting member. The elastic member includes a fixing portion, a compressive portion and an elastic portion. The fixing portion is connected to the shell. The compressive portion is configured to abut against the switch. The elastic portion is connected between the fixing portion and the compressive portion. The elastic portion is suitable for deformation. The button is connected to the compressive portion, and the compressive portion is located between the button and the switch. The adjustable limiting member is disposed on the button, and is configured to abut against the elastic portion. The adjustable limiting member adjustably protrudes for a length toward the elastic portion relative to the button.
