Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing add-on optical touch screens for liquid crystal displays are fixed in size, making them unsuitable for displays of varying sizes and requiring multiple purchases, which increases storage space and waste due to their unadjustable nature.
Innovation Solution
An add-on touch device with adjustable sensing and fixing modules connected by a reflective connector, allowing the touch area to expand or contract to fit different display sizes, and featuring scroll members to store excess connector length for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size of add-on optical touch screens is increased to fit larger displays, then the applicability to larger displays is improved, but the storage space occupied increases
Solution Approach 1:
The touch screen device incorporates a reflective connector with scroll members that enable the connector length to be dynamically adjusted. When the device is not in use, the scroll members wind up the reflective connector to reduce the device volume for compact storage. When in use, the connector can be extended to match different display sizes, providing adaptability without permanently occupying large storage space.
2Adaptability or versatility
If multiple add-on optical touch screens of different sizes are purchased to fit various displays, then the adaptability to different display sizes is improved, but the cost and waste increase
Solution Approach 1:
The touch screen device is designed as a universal solution that can adapt to multiple display sizes through the adjustable reflective connector. The scroll members enable the connector length to be modified according to the specific display size required, allowing a single device to serve multiple functions across different display configurations, thereby eliminating the need to purchase and discard multiple specialized touch screens.
3Adaptability or versatility
If the reflective connector length is increased to accommodate larger displays, then the adaptability to larger displays is improved, but the device volume increases
Solution Approach 1:
The reflective connector is integrated within the housing structure and can be wound around the scroll members like a nested configuration. When not in use, the connector is compacted within the housing volume by the scroll mechanism, allowing the device to maintain a small form factor while still having the capability to extend to larger sizes when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the touch device to be easily adapted to various display sizes while minimizing storage space by adjusting the reflective connector length and compacting the device for storage, thus reducing waste and cost.
Implementation Method 1
The plurality of sensing modules and the plurality of fixing modules are connected by at least a reflective connector, forming a touch area
Data Source
AI summary
The present disclosure provides an add-on touch device and the sensing module thereof. The add-on touch device comprises at least a sensing module and a plurality of fixing modules. The sensing module and the plurality of fixing modules are disposed on the four edges of a display and connected by at least a reflective connector for forming a touch area corresponding to a display area of the display. The touch area covers the display area, so that the sensing module can sense the position in the display area touched by a user in the touch area. The length of the reflective connector of the add-on touch device disclosure is adjusted according to the sum of the distances between the sensing module and the plurality of fixing modules; the sum of the distances between the sensing module and the plurality of fixing modules changes according to the size of the display.
