Sliding Input Auxiliary Device for Touch Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals with detachable cover sections often lose the cover when detached and fail to reattach easily, disrupting user input operations.
Innovation Solution
A display device with a touch sensor and an input auxiliary device that can slide between a position above the screen and a standby position, allowing users to perform input operations without losing the device, and enabling visual checking of the screen by moving the auxiliary device out of the way.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable cover section is provided with keys for operating the touch panel, then input operations can be performed, but the cover section can be easily lost when detached and is not readily reattached
Solution Approach 1:
The input auxiliary device is extracted from the detachable cover section and can be independently positioned above or beside the screen. This allows the input device to be separated from the cover, eliminating the loss problem while maintaining input functionality through the touch sensor that detects contact positions on the screen.
Solution Approach 2:
The touch sensor acts as an intermediary between the input auxiliary device and the display device. It detects the contact position of the operation element on the screen and transmits this information to the controller, enabling input operations without requiring a physical connection or attachment mechanism.
2Ease of operation
If the input auxiliary device is placed above the screen for input operations, then input capability is improved, but the device obstructs the user's view of the screen
Solution Approach 1:
The input auxiliary device is designed to be movable rather than fixed, allowing it to be dynamically positioned above the screen during input operations and moved to a standby position beside the screen when not in use. This dynamic positioning resolves the contradiction between input capability and screen visibility.
3Measurement precision
If the contact position for input operation depends on the position of the input auxiliary device, then input precision is improved, but the user must accurately adjust the position of the input auxiliary device
Solution Approach 1:
The touch sensor provides feedback by detecting the contact position of the operation element on the screen. The controller receives this detection result and identifies the contact position, allowing the system to automatically determine the input position without requiring the user to manually adjust or precisely position the input auxiliary device.
