Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floating roofs in liquid storage tanks are susceptible to damage due to accumulation of rainwater or other fluids in the pontoons, leading to buoyancy issues and structural damage, as existing mechanisms lack sufficient sensitivity and rapid detection capabilities.
Innovation Solution
A water level indicator for pontoon tanks comprising a fixed support mechanism, an extension system with an extension rod adjustment, and a movable portion with multiple levers that cooperatively displace a gauge rod in proportion to fluid levels, enhancing sensitivity and detection of fluid accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple float mechanism is used, then the device complexity is reduced, but the measurement precision and sensitivity to water level changes deteriorates
Solution Approach 1:
The float mechanism is segmented into multiple functional components: a main float body, an extension rod system with adjustment capability, and a lever mechanism with multiple arms. This segmentation allows each component to contribute specifically to sensitivity while keeping individual parts relatively simple.
Solution Approach 2:
The extension rod acts as an intermediary element between the float and the gauge rod, transmitting and amplifying the float's movement. The lever mechanism serves as another intermediary that further amplifies the displacement signal, enabling high measurement precision without requiring a complex overall structure.
2Stability of the object's composition
If a fixed support mechanism is used, then the stability of the mechanism is improved, but the adaptability to different tank configurations deteriorates
Solution Approach 1:
The support mechanism incorporates dynamic adjustment capabilities through the extension rod adjustment system, allowing the fixed support structure to be configured for different tank heights and orientations. The lever mechanism can also be adjusted to optimize performance for specific tank configurations while maintaining operational stability.
Solution Approach 2:
The fixed support mechanism is designed with universal mounting options that can accommodate various tank types and configurations. The adjustment systems enable the same basic structure to serve multiple functions across different installation scenarios, from vertical to inclined tanks.
3Adaptability or versatility
If an extension rod adjustment system is added, then the adaptability to different tank configurations is improved, but the device complexity increases
Solution Approach 1:
The adjustment functionality is extracted as a separate, modular extension rod adjustment system that can be independently configured. This allows the core float mechanism to remain relatively simple while the adjustment capability is added as a distinct subsystem with standardized components.
4Measurement precision
If multiple levers are used to amplify displacement, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The lever mechanism is merged with the extension rod system in an integrated assembly, where the levers are positioned to work in conjunction with the extension rod's movement. This merging reduces the need for separate adjustment mechanisms and simplifies the overall structure while maintaining the displacement amplification function.
