Adjustable-Angle Spirit Level With Handwheel Bubble Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spirit levels have a limited adaptable range due to fixed level bubbles, allowing measurement of only a special angle, restricting their usability.
Innovation Solution
A spirit level with an adjustable measuring angle, featuring a rotating carrier and adjusting handwheel, linked by a linkage assembly, allows users to adjust the angle of the level bubble using a reading structure with a main scale and vernier scale for precise measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the level bubbles are fixed with respect to the body, then the structure is simple, but only a special angle can be measured horizontally and the adaptable range is relatively small
Solution Approach 1:
The level bubble is made adjustable through a rotating carrier that can be rotated to different angles using an adjusting handwheel. The reading structure with main scale and vernier scale enables precise angle measurement, transforming the fixed bubble design into a dynamic, adjustable system that can measure various angles while maintaining structural organization through the linkage assembly.
2Ease of operation
If the adjustable level bubble and reading structure are positioned for easy adjustment, then the adaptability is improved, but the user's hand may block the view of the bubble and reading
Solution Approach 1:
The adjusting handwheel is positioned in a location that allows the user to operate it from the side, while the level bubble and reading structure are arranged in a different spatial plane that remains visible. This dimensional separation ensures that the user's hand does not block the view of the measurement elements during adjustment, solving the view obstruction problem while maintaining ease of operation.
