Liquid-Level Detection Device Rotatable Range Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-level detection devices struggle to accurately adjust the rotatable range of their components to match the shape of various containers, as they often rely on shared core components that cannot be easily modified to fit specific container shapes.
Innovation Solution
A liquid-level detection device is designed with a rotatable body and a supporting body that includes a rotation contact part and a supporting contact part, along with an attachment member that adjusts the rotatable range by making contact with the rotatable body before it contacts the supporting body, allowing for arbitrary adjustment of the rotatable range without altering the core component's shape.

1Manufacturing precision
If the rotatable range is adjusted by changing the shape of core components (arm holder or sensor frame), then the rotatable range can correspond accurately to the container shape, but the core components cannot be shared across different liquid-level detection devices
Solution Approach 1:
The invention divides the rotation restriction function into two separate parts: the supporting body (core component) and the attachment member (adjustable component). The supporting body contains the supporting contact part that provides the basic rotation restriction, while the attachment member contains the attachment contact part that can be adjusted to modify the rotatable range. This segmentation allows the core supporting body to remain standardized and shareable across different devices, while the attachment member is customized for specific container shapes.
Solution Approach 2:
The attachment member acts as an intermediary between the supporting body and the container shape requirements. It mediates the interaction by providing an adjustable attachment contact part that modifies the rotation restriction without requiring changes to the core supporting body structure. This intermediary component enables accurate adaptation to different container shapes while preserving the shareability of the core components.
2Adaptability or versatility
If three pairs of stepped stopper surfaces are provided for the sensor frame, then the rotatable range can be adjusted to three preset steps, but the adjustment granularity is insufficient for arbitrary container shapes
Solution Approach 1:
The invention transitions from a static, fixed-step adjustment mechanism (three preset stopper surfaces) to a dynamic, continuously adjustable mechanism. The attachment member can be positioned at different locations around the supporting body, allowing the rotatable range to be adjusted to any angle rather than being limited to three predetermined steps. This dynamic adjustment capability enables precise matching to arbitrary container shapes.
Solution Approach 2:
The invention changes the adjustable parameter from discrete angular steps (three fixed positions) to continuous angular adjustment. By allowing the attachment member to be positioned at various angles around the supporting body, the system transforms the rotation restriction from a quantized set of values to a continuous range, enabling precise adaptation to different container geometries.

AI summary
A liquid-level detection device detects a level of a surface of liquid stored in a container. The liquid-level detection device includes: a float that floats on the surface of liquid; a rotatable body that rotates due to a upward or downward displacement of the float and includes a rotation contact part; a supporting body that rotatably supports the rotatable body and includes a supporting contact part which is located on a rotational track of the rotation contact part to restrict the rotation of the rotatable body in a specified direction by contact between the supporting contact part and the rotation contact part; and an attachment member that is attached to the supporting body and includes an attachment contact part which makes contact with the rotatable body rotating in the specified direction to prevent the contact of the rotation contact part with the supporting contact part.
