Solution Overview
Problem
Existing controller mechanisms for electronic devices either lack tactile feedback or have static appearances, leading to user confusion and dissatisfaction.
Innovation Solution
A controller mechanism that combines a touchscreen with a pushbutton mechanism, featuring a selectable actuator with protrusions that prevent lateral movement, providing both tactile feedback and a dynamic user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical pushbutton mechanism is used, then tactile feedback is provided, but the appearance remains static and visually unappealing
Solution Approach 1:
The patent combines a mechanical pushbutton mechanism with a touchscreen display by integrating the button structure through the touchscreen surface. The pushbutton actuator is positioned beneath the touchscreen, allowing the screen to display dynamic visual feedback (highlighting, animations) while the mechanical button provides tactile feedback. This merging resolves the contradiction by enabling both mechanical tactile response and dynamic visual appearance simultaneously.
2Shape
If a touchscreen mechanism is used, then visual appeal and dynamic appearance are improved, but tactile feedback is lost
Solution Approach 1:
The patent merges touchscreen functionality with mechanical pushbutton structure by positioning the actuator beneath the touchscreen surface. The touchscreen provides dynamic visual feedback through highlighting and animations, while the mechanical button structure embedded in the screen surface provides tactile feedback. Users can feel the button press through the touchscreen surface, resolving the contradiction between visual appeal and tactile feedback.
3Measurement precision
If mechanical buttons are made precise, then activation accuracy is improved, but lateral movement and play increase causing user confusion
Solution Approach 1:
The patent segments the button structure into distinct functional components: a top surface for user interaction, vertical walls that constrain lateral movement, and a bottom actuator for signal generation. The vertical walls are positioned at specific distances from the top surface to limit lateral displacement. This segmentation allows precise vertical activation while constraining lateral movement, resolving the contradiction between activation accuracy and stability.
4Ease of operation
If the actuator is freely movable, then ease of operation is improved, but excessive play and lateral movement occur
Solution Approach 1:
The patent segments the actuator structure with vertical walls that create constrained movement zones. These walls are positioned at specific distances from the top surface to allow vertical pressing motion while preventing excessive lateral movement. The segmentation maintains operational ease through responsive vertical actuation while controlling lateral play, resolving the contradiction between ease of operation and movement stability.
