Solution Overview

Problem

Existing liquid level monitoring and alarm systems, including those using floating magnets, lack versatility and convenience for user manipulation, making them inefficient for precise fluid level control and operation.

Innovation Solution

A float-operated electric switch actuating mechanism with an adjustable rod, cross beam, and counterweights that activates/deactivates an electric switch based on fluid level changes, allowing for precise control and minimizing 'bounce' effects from fluid waves, using adjustable nuts and a pivot mechanism for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a floating magnet system is used for liquid level monitoring, then the device can detect fluid level changes, but the system lacks versatility and is inconvenient for user manipulation

Engineering Contradiction:
Improvefluid level detection accuracyVSAvoiduser manipulation convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements adjustable limit nuts that can be positioned at different heights along the rod, allowing the sensing range and trigger levels to be dynamically configured by the user based on specific application requirements, thereby resolving the contradiction between precise measurement and ease of operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The float assembly is designed with a universal structure that can be applied to various container types and fluid levels through adjustable limit nuts and a configurable rod mechanism, making it versatile while maintaining precise fluid level detection capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Speed

If the rod is allowed to move freely in response to fluid waves, then the float responds quickly to level changes, but false activations occur due to wave bounce effects

Engineering Contradiction:
Improveresponse speed to level changesVSAvoidswitch activation stability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The limit nuts are positioned to define a controlled travel range for the rod, preventing excessive movement caused by fluid waves before false activation can occur, while still allowing sufficient travel for accurate level detection

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The mechanical connection between the cross beam and electric switch includes a pivot point that acts as a cushioning mechanism, absorbing the impact of sudden rod movements from waves and preventing false switch activations while maintaining responsive detection

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If the float displacement range is increased to cover larger fluid volume changes, then the monitoring range is expanded, but the device complexity increases

Engineering Contradiction:
Improvemonitoring rangeVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rod is segmented with adjustable limit nuts at different positions, allowing the monitoring range to be divided into discrete adjustable segments. This enables flexible configuration of the monitoring range without increasing overall device complexity, as each segment can be independently adjusted

Inventive Principle:
Principle #1Segmentation
