Solution Overview
Problem
Existing measuring devices with touch-sensitive screens face inefficiencies in using screen area for magnified displays, making it difficult to select and view relevant regions of measurement signals, and require complex gestures for magnification, leading to non-intuitive operation.
Innovation Solution
A measuring device with a touch-sensitive screen that allows magnification of measurement signals by tapping on a region of interest, with adjustable magnification levels and emphasis through brightness, color, and sharpness, and the ability to seamlessly transition between magnified and non-magnified views based on touch pressure and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a magnification function displays an overview curve in a small size and a magnified curve in a separate diagram, then the measurement signal can be viewed at different scales, but the screen area is inefficiently used and the display becomes non-intuitive
Solution Approach 1:
The patent combines the overview display and magnified display into a single integrated display area. When a user touches a region of interest, the measurement signal is displayed magnified in that specific region while the rest of the screen maintains the overview, eliminating the need for separate diagrams and providing an intuitive single-screen interaction.
Solution Approach 2:
The patent introduces a spatial dimension to magnification by allowing the magnified region to be positioned at the exact location touched on the screen. This creates a layered display where the magnified view appears in-context at the touched position rather than being moved to a separate area, improving both precision and intuitiveness.
2Measurement precision
If a magnification function displays an overview curve and a magnified curve in separate diagrams, then the measurement signal can be viewed at different scales, but a significant part of the screen is occupied by the overview curve reducing availability for the relevant region
Solution Approach 1:
The patent applies local quality by displaying the measurement signal with different magnification levels in different regions of the screen simultaneously. The touched region receives high magnification for detailed viewing, while the remaining screen area maintains the overview display, optimizing the use of available screen space for both contexts.
Solution Approach 2:
The patent segments the display area into a magnified region and an overview region. The magnified region is dynamically positioned at the touched location and occupies only the necessary area for detailed viewing, while the rest of the screen continues to display the overview, maximizing the utilization of total screen area.
3Measurement precision
If a two-finger gesture is used for magnification by moving fingers apart, then magnification can be achieved, but the operating process requires learning and is not intuitive
Solution Approach 1:
The patent makes the system self-service by automatically detecting the user's region of interest through a simple touch gesture and automatically providing the magnified view in that region. The system adapts to the user's intent without requiring the user to learn specific gesture protocols, making the complex magnification function as intuitive as a simple tap.
Solution Approach 2:
Instead of requiring the user to perform complex gestures to trigger magnification, the patent inverts the approach by making the simple touch the trigger and having the system automatically provide magnification. This reverses the complexity from the user side to the system side, greatly simplifying the operating interface.

AI summary
A measuring device serves for the measurement and display of at least one measurement signal. It contains a measuring unit for the measurement of the at least one measurement signal and a display unit. In this context, the display unit comprises a processing unit and a touch-sensitive screen. The processing unit is embodied in order to display the at least one measured measurement signal by means of the touch-sensitive screen and to register and process touches on the touch-sensitive screen. The processing unit is further embodied in order, in the case of a touch of the touch-sensitive screen in a first position, to display the displayed at least one measured measurement signal in at least one first region around the first position magnified with a first magnification.
