Button Element Open Cantilever Structure for Off-Center Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button elements in electronic devices often experience pressing center deviation due to exterior design and internal structural arrangements, leading to deflected pressing and potential failure to trigger the touch switch.
Innovation Solution
A button element with an open portion extending from a first connection end to an open end, including a first cantilever and an open anchoring area, which is fixedly connected to the housing, ensuring stability and suppressing excessive skew during pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the button element is mounted on the housing with a touch switch adjacent to it, then the user can press the button element to trigger the touch switch, but the pressing center of the touch switch may deviate from the center of the button element due to exterior design and internal structural arrangements
Solution Approach 1:
The button element is divided into distinct functional segments: a pressing portion for user interaction and an open portion with cantilever structures for mechanical support. This segmentation allows the pressing portion to be optimized for user operation while the open portion with its anchoring area ensures precise positioning relative to the touch switch, resolving the alignment deviation issue.
Solution Approach 2:
The open portion acts as an intermediary structure between the pressing portion and the housing. It includes a first cantilever and an open anchoring area that mediates the connection, ensuring the pressing portion remains properly aligned with the touch switch contact portion even when exterior design or internal structures cause eccentricity.
2Reliability
If the user presses the button element under too large eccentricity, then the button element may be pressed deflectedly or the touch switch cannot be triggered, but increasing the structural complexity to prevent this reduces ease of manufacture
Solution Approach 1:
The open portion incorporates a first cantilever that provides dynamic flexibility during pressing. This cantilever structure allows the button element to accommodate certain degrees of eccentricity and deflection without compromising reliability, while maintaining a relatively simple manufacturing process compared to more rigid complex structures.
Solution Approach 2:
The design changes the structural parameters of the button element by introducing an open portion with specific geometric features (first cantilever, open anchoring area). This parameter change enables the button to tolerate eccentric pressing forces while maintaining reliable touch switch triggering, without requiring overly complex manufacturing processes.
3Stability of the object's composition
If the button element is designed with a traditional closed structure, then it provides structural stability, but it cannot effectively suppress excessive skew during pressing
Solution Approach 1:
The open portion features an asymmetric design with a first cantilever and an open anchoring area that is not fully enclosed. This asymmetric structure provides both structural stability for overall button integrity and the flexibility to suppress excessive skew during pressing by allowing controlled movement in specific directions while maintaining positional stability.

Function Achieved in This Case
The button element design ensures stable sinking of the pressing portion, suppresses excessive skew, and improves the reliability of triggering the touch switch, enhancing the overall pressing feel and reducing failure rates.

AI summary
A button element has an elasticity and is configured for being connected to a housing. The button element includes a pressing portion and an open portion. The pressing portion is configured for being exposed from an opening of the housing for a user to press. The open portion extends from a first connecting end to an open end and includes a first cantilever and an open anchoring area in sequence. The first connecting end is connected to the pressing portion, and the open anchoring area is configured to be fixedly connected to the housing.
