Liquid Level Detector Compact Rotation Regulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid level detectors require a large body size due to the need for grooves to regulate the rotation angle range of the arm, limiting their compactness and efficiency.
Innovation Solution
The design incorporates multiple rotation regulators with non-overlapping rotation angle ranges, utilizing stoppers to regulate the arm's rotation without the need for side walls, allowing for a more compact body size by eliminating the requirement for groove-shaped rotation regulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grooves are formed in the body to regulate the rotation angle range of the arm, then the rotation can be controlled, but the body size increases
Solution Approach 1:
The rotation regulator is divided into multiple independent stoppers (first stopper, second stopper, third stopper, fourth stopper) that can be selectively engaged with the arm. Each stopper provides a discrete rotation limit, allowing the system to achieve rotation regulation without requiring large grooves. The stoppers are arranged at different angular positions around the rotation axis, enabling compact segmentation of the regulation function.
Solution Approach 2:
Instead of using grooves that extend radially outward from the rotation axis (occupying lateral space), the invention uses stoppers that protrude axially from the body in the rotation direction. This dimensional shift allows the regulation mechanism to occupy space along the rotation axis rather than radially, effectively reducing the body's lateral dimensions while maintaining regulation capability.
2Reliability
If groove-shaped rotation regulators are used, then rotation regulation is achieved, but side walls are required increasing device complexity
Solution Approach 1:
The rotation regulator is segmented into multiple independent stoppers rather than forming a continuous groove structure. Each stopper is a discrete component that can be independently positioned and engaged with the arm, simplifying the overall structure by eliminating the need for continuous side walls and complex groove geometries.
Solution Approach 2:
Instead of forming grooves that constrain the arm from the inside, the invention uses protruding stoppers that constrain the arm from the outside. This inverted approach replaces the complex internal groove structure with simpler external stoppers, reducing device complexity while achieving the same rotational constraint function.

AI summary
A liquid level detector may comprise an arm attached to a float, a holder fixed to the arm, and a body rotatably supporting the holder. The body may comprise a first rotation regulator and a second rotation regulator. The first rotation regulator may regulate a rotation angle range of the arm to a first range. The second rotation regulator may regulate the rotation angle range of the arm to a second range. The first range and the second range may not overlap each other in a rotation direction of the arm. Each of the plurality of rotation regulators may comprise a pair of stoppers disposed separately from each other in the rotation direction of the arm. At least a part of area between the pair of stoppers of the each of the plurality of rotation regulators may be open to outside of the body.
