Distance Measuring Device Rotating Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distance measuring devices are uncomfortable to use in applications where the device must be rotated relative to the user, as the display content cannot be optimally read from the front, requiring users to laboriously turn the device to view the measurements.
Innovation Solution
Equipping the device with a pivot function that allows the display content or sections to rotate by a predetermined or definable angle, enabling users to read the display from different positions, either manually or automatically using position sensors, with options for 90° rotation steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance measuring device is rotated relative to the user for special measuring tasks (e.g., measuring on a wall or window), then the device can be positioned for the measurement task, but the display content cannot be optimally read from the front
Solution Approach 1:
The display content is made dynamically rotatable through software control, allowing it to change orientation relative to the device housing. The display can rotate in steps (e.g., 0°, 90°, 180°, 270°) to match the device's physical orientation, ensuring the content remains readable regardless of how the device is positioned during measurement tasks.
Solution Approach 2:
The orientation parameter of the display content is changed based on the device's physical orientation. When the device is rotated to a specific angle for measurement, the display content rotates by the same angle to maintain proper readability. This parameter transformation resolves the contradiction between device positioning flexibility and display readability.
2Ease of operation
If the user turns the entire distance measuring device to read the display content, then the display content can be read from the front, but the operation becomes laborious and inconvenient
Solution Approach 1:
The display content automatically adjusts its orientation based on the device's physical position. Through the pivot function, the display rotates itself to match the device's orientation, eliminating the need for the user to manually turn the device to read the content. This self-adjusting mechanism saves time and effort.
Solution Approach 2:
The system detects the device's orientation (either manually through input units or automatically through position sensors) and uses this feedback to rotate the display content to the appropriate angle. This closed-loop control ensures the display remains readable without requiring user intervention to reposition the device.
3Adaptability or versatility
If the display content is made rotatable, then the user can read the display from different positions, but the device complexity increases
Solution Approach 1:
Instead of using a mechanical pivot mechanism to physically rotate the display hardware, the invention uses software to rotate the display content virtually. This substitution of mechanical complexity with software control achieves the same functional result (readable display at different orientations) with minimal added complexity.
Solution Approach 2:
The display content is segmented into rotatable elements that can be independently rotated. The pivot function operates on specific portions of the display content, allowing different sections to be rotated to appropriate orientations based on the device's physical position, thereby achieving flexibility without requiring complete system reconfiguration.
