Tactile Sensor Rocker with Form-Fitting Adapter for Precise Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-button sensors require additional tools like frames or screens for precise positioning of the operating rocker, which restricts design creativity and prevents the creation of minimalist designs.
Innovation Solution
The operating rocker features a form-fitting adapter with perpendicular boundary walls that accommodate the restoring element, allowing for precise alignment with the circuit board without external aids, enabling the rocker to pivot and return to a rest position without design restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additional tools such as frames or screens are used for precise positioning of the operating rocker, then positioning precision is improved, but device complexity and design freedom deteriorate
Solution Approach 1:
The patent integrates the positioning function directly into the operating rocker component itself through the form-fitting adapter with boundary walls, eliminating the need for separate frames or screens. The adapter's boundary walls engage with corresponding features on the circuit board to provide precise positioning, merging the positioning function into the rocker assembly and reducing overall device complexity.
Solution Approach 2:
The form-fitting adapter acts as an intermediary element between the operating rocker and the circuit board. This adapter provides the precise positioning interface without requiring additional external tools, mediating the connection and alignment between the rocker and circuit board while maintaining design simplicity.
2Manufacturing precision
If frames or screens are used to position the operating rocker, then positioning precision is improved, but design freedom and aesthetic quality deteriorate
Solution Approach 1:
The positioning functionality is merged into the operating rocker's form-fitting adapter, allowing the decorative portion to be designed freely without constraints from external frames or screens. The adapter provides necessary positioning while the rocker's visible portions can be optimized purely for aesthetic purposes.
Solution Approach 2:
The operating rocker is segmented into functional portions (adapter with boundary walls for positioning) and decorative portions (visible surfaces). This segmentation allows independent optimization of each portion - the adapter ensures precise positioning while the decorative portions provide design freedom and aesthetic quality.

Function Achieved in This Case
This solution allows for precise positioning of the operating rocker relative to the circuit board, enhancing the tactile feedback and reproducibility of the touch sensor while maintaining a minimalist design aesthetic.
Implementation Method 1
the push-button sensor has at least one restoring element arranged on the operating rocker, via which the operating rocker is prestressed from an operating position, in which the operating rocker actuates at least one of the switching elements, into a rest position, in which the operating rocker does not actuate any of the switching elements

AI summary
The invention relates to a touch sensor with a circuit board carrier for surface mounting, a circuit board arranged on the circuit board carrier on which at least two switching elements are arranged, and with at least one rocker switch for actuating the switching elements, wherein the touch sensor has at least one return element arranged between the circuit board carrier and the rocker switch, by means of which the rocker switch is biased from an actuating position in which the rocker switch actuates at least one of the switching elements to a rest position in which the rocker switch does not actuate any of the switching elements, characterized in that the rocker switch is pivotably mounted about a pivot axis with respect to which the at least two switching elements are arranged opposite each other, wherein the rocker switch has a positive-locking adapter on its side facing the circuit board in which the return element is positively received.
