Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multipoint measurement systems using dial gauges struggle to visually grasp the quantitative trend of a measured object's shape due to difficulty in reading rotational angles and interpreting the shape from multiple measurement points.
Innovation Solution
A digital indicator and multipoint measuring apparatus featuring a display device with a movable spindle, displacement detecting sensor, and display controller that linearly moves a measured value display mark on the display surface, allowing for visual representation of the measurement surface trend and tolerance checking, enabling easy switching between digital and mark display modes for dimension and trend measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dial gauges are used for multipoint measurement, then measurement capability is provided, but visual grasping of quantitative trend becomes difficult
Solution Approach 1:
The patent creates a visual copy of the measurement data by displaying measured values as marks on a display surface that represents the measured object's shape. Instead of directly reading dial gauge needles, the system generates a graphical representation where marks indicate measurement points and their positions reflect the quantitative trends of the measured object's shape.
Solution Approach 2:
The patent replaces the mechanical dial gauge reading system with an electronic display system. The mechanical rotation of dial gauge needles is substituted by electronic marks displayed on a screen, which can be visually interpreted to show trends without requiring manual reading of rotational positions.
2Quantity of substance
If multiple dial gauges are installed at predetermined positions, then multipoint measurement is enabled, but reading rotational angles from scales becomes complex
Solution Approach 1:
The system creates a simplified visual copy of multiple measurement points on a display surface, where each measurement point is represented by a mark whose position corresponds to the measured value. This eliminates the need to read multiple separate dial gauges with scales, as all information is presented in a single graphical representation.
Solution Approach 2:
The patent merges multiple measurement readings into a single integrated display. Instead of separately reading multiple dial gauges, all measurement point data is combined and presented together on one display surface, showing the spatial relationship and trends of all measurement points simultaneously.
3Measurement precision
If dial gauges with scales are used, then measurement function is provided, but grasping shape at once becomes difficult
Solution Approach 1:
The system creates a direct visual copy of the measured object's shape characteristics by displaying marks on a representation of the measured object. This allows the overall shape and trends to be grasped immediately without sequentially reading multiple dial gauge scales, significantly reducing the time required to understand the measured geometry.
Solution Approach 2:
The patent transitions from one-dimensional dial gauge scale readings to a two-dimensional display surface that represents the measured object's shape. By mapping measurement values to positions on this display surface, the system enables simultaneous visualization of multiple measurement points and their spatial relationships, allowing rapid comprehension of the overall shape.
