Dual-Probe Fluid Sensor Assembly Space-Constrained Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid sensor assemblies for tanker trailers face challenges in space constraints and accessibility due to limited space around sensor assemblies and complex configurations, making installation and maintenance difficult, especially when multiple components like visual inspection covers, tank access covers, and fluid sensors are present on a single man-lid.
Innovation Solution
The design incorporates articulating levers that rotate to lock the cap to the base, reducing the space required for cap attachment and detachment, and a rotatable base/flange assembly that allows customizable wiring port positioning and easier wire routing, along with a dual-sensor assembly that uses a semi- or fully-toolless installation method to conserve space and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cap attachment methods are used, then secure locking is achieved, but large space is required for cap attachment and detachment operations
Solution Approach 1:
The cap attachment mechanism is segmented into multiple locking points around the perimeter, allowing incremental engagement rather than requiring full-cap alignment. This enables the cap to be attached and detached in smaller, more manageable movements, reducing the operational space required.
Solution Approach 2:
The locking mechanism transitions from a static alignment requirement to a dynamic engagement process where the cap can be attached through rotational or incremental movements. This dynamic approach allows the cap to self-align during attachment, reducing the precision and space needed for the operation.
2Adaptability or versatility
If multiple sensors are installed in separate assemblies, then comprehensive monitoring is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
Multiple sensor assemblies are merged into a single integrated housing that accommodates multiple sensors simultaneously. This unified structure reduces the overall number of separate components, simplifies installation by providing a single mounting location, and maintains comprehensive monitoring coverage through multiple sensors working together within the same assembly.
Solution Approach 2:
The sensor assembly housing is designed as a universal platform that can accommodate different types and configurations of sensors. This multi-functional design allows the same basic assembly structure to support various sensor arrangements, reducing complexity by eliminating the need for specialized housings for each sensor type while maintaining adaptability and comprehensive monitoring capability.
3Ease of operation
If fixed wiring port positioning is used, then manufacturing simplicity is maintained, but wiring access flexibility is reduced
Solution Approach 1:
The wiring port positioning system transitions from fixed to adjustable, allowing the ports to be repositioned along designated pathways or rotated to different orientations. This dynamic positioning capability maintains manufacturing simplicity by using standardized mounting features while providing wiring access flexibility to accommodate different installation scenarios and wire routing requirements.

AI summary
A dual-sensor fluid sensor assembly is provided. The dual-sensor fluid sensor assembly includes a probe holder, a base, and a spring. The probe holder is configured to receive and secure two fluid sensor probes. The base is configured to receive and secure the holder upon rotation of the holder into the base. The spring is positioned between the holder and the base, the spring being positioned to exert a repelling force between the holder and the base to secure the holder to the base.
