Mobile Terminal Control for Multi-Device Lab Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic measuring devices in lab settings often have small touch screens, impairing user-friendliness and increasing the effort required to control, program, or read out a large number of identical or similar devices.
Innovation Solution
A system utilizing a mobile terminal to control and identify multiple measuring devices wirelessly, eliminating the need for on-device screens and buttons, and using a server for data management and identification through unique codes or QR codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If measuring devices are equipped with touch screens and control buttons, then the devices can be operated independently, but the device complexity and manufacturing costs increase
Solution Approach 1:
The control interface (touch screen and buttons) is extracted from the measuring device and relocated to an external mobile device. The measuring device retains only the essential measurement functionality, while control, programming, and data reading operations are performed remotely through wireless communication, thereby reducing device complexity and manufacturing costs.
Solution Approach 2:
A single mobile device serves as the universal control interface for multiple measuring devices. The mobile device runs an application that can control different measuring devices, eliminating the need for each measuring device to have its own dedicated control interface, thus reducing overall system complexity.
2Measurement precision
If multiple identical measuring devices are controlled individually, then each device can be operated precisely, but the time and effort required increases significantly
Solution Approach 1:
Multiple measuring devices are merged into a single controllable system through the mobile device application. The application displays multiple devices in a list or graphical interface, allowing the user to select and control one or more devices simultaneously from a single location, thereby dramatically reducing the time and effort required to manage multiple devices while maintaining precise control over each.
3Volume of moving object
If small touch screens are used in measuring devices, then the devices remain compact, but user-friendliness deteriorates
Solution Approach 1:
The mobile device acts as an intermediary between the user and the measuring device. Instead of requiring the user to interact directly with the small touch screen of the measuring device, the mobile device provides a larger, more user-friendly interface for control and data display, while maintaining wireless communication with the compact measuring device.
