Vehicle Touch Input Apparatus with Recessed Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch input apparatuses for vehicles are complex in structure due to the inclusion of dials, making it difficult to maintain an aesthetic appearance and increasing the error rate of user input, especially when users need to input gestures without focusing on the touch area.
Innovation Solution
A touch input apparatus with a protrusion and recessed portion that allows for intuitive touch signal input without the need for a dial, featuring a central and peripheral touch area with inclined surfaces for gesture recognition, enabling users to input commands through touch and gesture without visual distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dial is included in the operation member, then the functional capability is enhanced, but the structure becomes complex and aesthetic effect is compromised
Solution Approach 1:
The patent removes the dial component from the operation member, extracting the problematic element that caused structural complexity while preserving the essential touch input functionality through the touch pad alone
Solution Approach 2:
The touch pad is designed to perform multiple functions that were previously divided between the touch pad and dial, including touch input, gesture recognition, and rotational input, thereby eliminating the need for a separate dial component
2Adaptability or versatility
If a dial is included in the operation member, then the functional capability is enhanced, but the aesthetic appearance is compromised
Solution Approach 1:
The dial component is removed from the design, eliminating the visual element that compromised aesthetic appearance while maintaining functional capabilities through the simplified touch pad interface
Solution Approach 2:
The functionality previously distributed between separate components (touch pad and dial) is merged into a unified touch pad design, creating a cleaner, more aesthetically pleasing appearance with fewer visible parts
3Measurement precision
If users focus on the touch area for input, then the accuracy is improved, but the user's sight is distracted from the display
Solution Approach 1:
The touch pad provides tactile feedback through its surface characteristics and button responses, allowing users to locate and operate controls through touch alone without needing to visually focus on the input area, thereby maintaining both accuracy and visual attention on the display
Solution Approach 2:
The operation member design allows users to intuitively locate and operate controls through tactile sensation and spatial memory, enabling the system to serve itself by eliminating the need for visual guidance during input operations

AI summary
A touch input apparatus mounted on a mounting surface includes a protrusion protruding from the mounting surface. A recessed portion is formed in the protrusion. A touch portion is provided on a bottom surface of the recessed portion and receives a user's touch signal. A vehicle having the touch input apparatus includes a display and a controller configured to operate the display according to the users input inputted to the touch input apparatus.
