Detachable Touch Input Device for Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch input devices for vehicles and health-related products face challenges in providing a precise and intuitive gesture input experience without requiring users to maintain eye contact with the input unit, and they lack customizable touch surface shapes to accommodate user preferences.
Innovation Solution
A touch input device with a detachable touch unit featuring a first and second touch portion on different surfaces, allowing users to input gestures on either surface, and a mounting system with screw units and signal connections for secure coupling and signal transmission, along with a touch sensor and coordinate converter for accurate gesture recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch input device uses a fixed touch surface shape, then the device structure is simple, but it cannot accommodate user preferences for different touch surface shapes
Solution Approach 1:
The touch input device is divided into a separate touch unit that can be detached and replaced. The touch unit includes a touch surface and a touch sensor, which are separated from the main device body, allowing users to exchange touch units with different surface shapes without changing the entire device structure.
Solution Approach 2:
The touch unit is designed to be selectively coupled to and detached from the device body, providing dynamic reconfigurability. This allows the touch surface shape to be changed according to user preference while maintaining a relatively simple base device structure.
2Ease of operation
If a touch input device requires eye contact for precise gesture input, then the input accuracy is high, but the user convenience deteriorates
Solution Approach 1:
The patent uses visual indicators (analogous to color changes in the principle) to guide users during gesture input. The device provides visual feedback through display elements that indicate the recognized gesture type and accuracy, allowing users to input gestures without maintaining eye contact while still achieving precise recognition.
Solution Approach 2:
The device incorporates a feedback mechanism that provides real-time visual information about the recognized gesture. This feedback loop allows users to verify their input accuracy without needing to look directly at the touch surface, improving ease of operation while maintaining measurement precision.
3Adaptability or versatility
If a touch input device uses a detachable touch unit, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The mounting structure is designed with universal coupling features that can accommodate different touch unit types. The coupling unit includes standardized connection elements that work with various touch unit configurations, providing multi-functionality while keeping the mounting structure itself relatively simple.
Solution Approach 2:
The mounting structure integrates multiple functions into a single compact unit, combining the coupling mechanism, signal connection, and mechanical support in one integrated assembly. This reduces the overall complexity compared to having separate components for each function.

AI summary
A touch input device includes a mounting unit in which a mounting groove is formed at an inner side of the mounting unit, and a touch unit accommodated in the mounting groove and installed to be detachable from the mounting unit, wherein the touch unit comprises a first touch portion and a second touch portion, which are provided on different surfaces of the touch unit and allow a user to input a touch gesture, and the touch unit is selectively coupled to the mounting unit to allow the first touch portion to face an upper side or to allow the second touch portion to face the upper side.
