Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumps are unable to maintain a consistent flow rate over a wide operating range regardless of medium viscosity, and they are prone to leakage in confined spaces, such as those found in stranded ships, leading to environmental pollution.
Innovation Solution
A pump design featuring a drivable spindle and at least two follower spindles arranged at a mutual angle, with an asymmetrical configuration and an inner pipe seal, allowing for compact dimensions and effective operation in narrow spaces, reducing leakage and maintaining consistent flow rates across varying viscosities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional pumps are used to maintain flow rate over wide operating range, then flow consistency is improved, but the pump cannot handle varying viscosities effectively
Solution Approach 1:
The pump is divided into multiple spindles (at least two spindles) that work independently within the housing. Each spindle contributes to the overall pumping action, allowing the system to maintain stable flow rates while adapting to varying viscosities through the combined effect of multiple independent elements
Solution Approach 2:
The spindles are arranged at mutual angles to each other, introducing a spatial dimension to the pumping mechanism. This angular arrangement allows the pump to handle varying viscosities effectively while maintaining consistent flow rates across a wide operating range
2Productivity
If pump capacity is increased to handle large volumes, then productivity is improved, but the pump dimensions become too large for confined spaces
Solution Approach 1:
By arranging spindles at mutual angles rather than in a linear configuration, the pump achieves high capacity within a compact housing volume. The angular arrangement optimizes space utilization and allows the pump to be introduced into confined spaces such as liquid conduits while maintaining high productivity
Solution Approach 2:
Multiple spindles are combined within a single housing to achieve high pump capacity. The spindles work together synergistically to deliver high productivity while sharing the space within the housing, avoiding the need for larger individual components
3Ease of operation
If pump is placed in confined spaces such as liquid conduits, then ease of operation in narrow spaces is improved, but leakage risk increases
Solution Approach 1:
A flexible sealing element is provided that can adapt to the confined space within the liquid conduit. The sealing element creates an effective seal between the pump housing and the conduit wall, preventing leakage while allowing the pump to operate in narrow spaces
Solution Approach 2:
The pump design with multiple spindles and modular housing allows for effective sealing in confined spaces. The segmented structure enables proper sealing arrangements that prevent leakage while maintaining compact dimensions suitable for conduit insertion
