Digital Display Orientation for Measuring Instrument Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital measuring instruments face difficulties in reading displayed values when the measurement is performed in conditions where the display surface is not easily visible, and they restrict the spindle's moving stroke due to the digital display's orientation.
Innovation Solution
A digital measuring instrument with a digital display surface arranged orthogonally to the spindle's moving direction, allowing for a long spindle stroke without restriction, and featuring a display inversion selector to ensure readability from any direction, along with an output connector positioned parallel to the spindle for unobstructed visibility.

Engineering Contradiction Analysis
1Ease of operation
If the digital display is arranged on the body case in a position right above the spindle to be orthogonal to the moving direction of the spindle, then the displayed value can be read from the axial direction of the spindle, but the moving stroke of the spindle is restricted by the digital display
Solution Approach 1:
The digital display is repositioned from a location directly above the spindle to a location on the side surface of the body case, changing its spatial dimension relative to the spindle axis. This dimensional repositioning allows the display to be viewed from directions other than the axial direction, eliminating the conflict between display visibility and spindle movement range.
2Device complexity
If the display surface is provided on the front surface of the body case parallel with the moving direction of the spindle, then the structure is simple, but the measured value is difficult to read when measurement is performed in conditions where it is difficult to visually check the display surface from the front side
Solution Approach 1:
The display surface is reoriented from being parallel to the spindle moving direction (front surface) to being orthogonal to the moving direction (side surface). This changes the viewing dimension from front-facing to side-facing, allowing operators to read the display from various measurement positions without requiring direct front access.
3Length of moving object
If the digital display is arranged orthogonally to the moving direction of the spindle and deviated from the moving axis, then the moving stroke of the spindle is not restricted, but the display may not be visible from all directions
Solution Approach 1:
The digital display is positioned asymmetrically on the side surface of the body case rather than symmetrically on the front or top surface. This asymmetric placement, combined with the orthogonal orientation to the spindle axis, creates a configuration where the display is accessible from multiple angles while maintaining full spindle movement range.

AI summary
A digital indicator 1 includes a body case (10), a spindle (30) provided to the body case (10), the spindle (30) being movable in an axial direction, a displacement detector (40) that detects a moving amount of the spindle (30), and a digital display (50) that digitally displays the moving amount detected by the displacement detector (40). The display surface of the digital display (50) is arranged on the body case (10) in an attitude substantially orthogonal to the moving direction of the spindle (30) and deviated from the moving axis of the spindle (30).
