Oblique-Angle Sensor Display for Multi-Directional Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensors with integrated displays are limited in their utility due to display visibility constraints, making it inconvenient to read or calibrate them on-site without external instruments, especially when the installation configuration prevents viewing from the top or rear.
Innovation Solution
The sensor design includes a display module that can be oriented between 25° to 65° relative to the zone axis, allowing visibility from both the rear and a direction perpendicular to it, along with an indicator and adjustment module for on-site operation and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is oriented perpendicular to the zone axis for easy reading, then visibility from the rear is improved, but visibility from the front/side directions deteriorates
Solution Approach 1:
The display is rotated 45 degrees relative to the zone axis, transitioning from a conventional perpendicular orientation to an oblique orientation. This angular repositioning allows the display to be simultaneously visible from multiple directions (front, side, and rear), resolving the contradiction between readability and installation flexibility by adding a dimensional aspect (angle) to the display orientation
2Adaptability or versatility
If the display is oriented at 45 degrees to the zone axis for multi-directional visibility, then installation versatility is improved, but display brightness and readability may deteriorate
Solution Approach 1:
The display module's orientation angle is changed from conventional values (0 or 90 degrees relative to zone axis) to an oblique angle of 45 degrees. This parameter change enables multi-directional visibility while the display module itself maintains its luminous properties, allowing it to be read from multiple angles without significant loss of brightness or readability

AI summary
A sensor comprises a detector defining a zone axis and adapted to receive a signal from within a zone around the zone axis and to generate an electrical signal, and a display module defining a display plane and adapted to display a pattern in the display plane based on the electrical signal, the display being oriented along an axis forming an angle with the zone axis such that the pattern is visible both from a direction parallel to the zone axis and from a direction perpendicular to the zone axis. In certain examples, the angle is about 45°, 40°-50°, 35°-55° or 25°-65°.
