Touch Screen Sensitivity Adjustment via Insertion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screen display devices face challenges in being easily inserted into and removed from a computer without compromising operational sensitivity, as exposed screens when removed are either left open or encased, affecting usability.
Innovation Solution
A touch screen display device with a sensor and control element that adjusts sensitivity based on insertion status into a connection chamber, using a sensitivity-setting element to enhance sensitivity when inserted, allowing for easy operation whether inserted or removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch screen is directly exposed from the computer body when the second device is removed, then the touch screen can be operated conveniently, but an opening is left in the computer body that needs to be filled
Solution Approach 1:
The touch screen display device is designed to be inserted into and stored within the computer body, nesting the exposed touch screen inside the computer body's connection chamber. This eliminates the need for an opening in the computer body while still allowing the touch screen to be operated when the second device is removed.
2Device complexity
If the second device is enclosed with a casing, then the computer body structure is maintained, but operation of the enclosed second device becomes difficult
Solution Approach 1:
The touch screen display device is segmented into a touch screen unit that can be independently inserted into and removed from the computer body's connection chamber. This allows the touch screen to be accessible and operable without requiring the entire second device to be enclosed in a casing, thus maintaining both structural integrity and operational ease.
3Measurement precision
If the touch screen sensitivity is increased for better touch response, then touch sensitivity is improved, but the touch screen becomes more prone to false detections and interference
Solution Approach 1:
The touch screen sensitivity is made dynamically adjustable based on the insertion status of the second device. When the second device is inserted, the touch screen operates with normal sensitivity. When the second device is removed, the sensitivity is automatically adjusted to a higher level to compensate for the changed operational environment, ensuring reliable touch detection in both states.

AI summary
A touch screen display device is provided. The touch screen display device includes a touch screen, a sensor, a control element and a sensitivity-setting element. The sensor is configured to detect if the touch screen display device is being inserted in a connection chamber. The control element is electrically connected with the sensor and is configured to generate a control signal according to an insertion status of the touch screen display device. The sensitivity-setting element is configured to set the touch screen to a first sensitivity or a second sensitivity according to the control signal. The touch screen with the first sensitivity is more sensitive than with the second sensitivity. A method for setting sensitivity of a touch screen is also provided.
