Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power cells for deepwater applications are complex, costly, and unreliable due to their large size and weight, which are required to withstand extreme pressures and temperatures, and often need additional insulation and pressure compensation systems.
Innovation Solution
The power cell system incorporates an insulating power cell housing made of materials like polyoxymethylene or polypropylene, a hermetically sealed structure, and a pressure compensation system, eliminating the need for additional insulation and simplifying the design by using a metallic frame and dielectric fluids to maintain internal and external pressure equality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power cells are designed with large size and weight to withstand extreme pressures and temperatures in deepwater, then reliability under deepwater conditions is improved, but production, transportation, and installation costs increase
Solution Approach 1:
The patent merges the pressure-resistant housing and insulation functions into a single integrated structure. The housing is made of an insulating material that simultaneously provides mechanical strength to withstand deepwater pressure and electrical insulation for the power electronics, eliminating the need for separate insulation layers and reducing overall complexity and cost.
Solution Approach 2:
The patent changes the material parameters by using insulating materials with high mechanical strength and pressure resistance properties. By selecting materials with appropriate tensile strength, modulus of elasticity, and pressure resistance characteristics, the housing can withstand deepwater conditions while maintaining a compact size and reducing weight compared to conventional metal pressure vessels.
2Reliability
If conventional power cells use additional insulation and pressure compensation systems, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the housing structure: pressure resistance, electrical insulation, and mechanical protection. This integration eliminates the need for separate insulation layers, pressure compensation systems, and protective enclosures, thereby reducing device complexity while maintaining reliability.
Solution Approach 2:
The housing structure serves multiple functions simultaneously: it provides mechanical strength to withstand pressure, electrical insulation for the power electronics, thermal management pathways, and structural support for mounting. This multi-functionality reduces the number of separate components needed and simplifies the overall system design.
3Ease of manufacture
If power cells are designed for deepwater application with insulating material housing, then ease of manufacture and reduced costs are improved, but the housing must withstand both mechanical pressure and provide electrical insulation
Solution Approach 1:
The patent changes the material parameters by selecting insulating materials with high mechanical strength, pressure resistance, and appropriate electrical properties. By adjusting material composition, thickness, and structural design parameters, the housing achieves the required balance between insulation performance and mechanical strength to withstand deepwater pressure.
Solution Approach 2:
The patent employs composite material structures that combine insulating materials with enhanced mechanical properties. The housing may use layered composites or reinforced structures that provide both electrical insulation and the necessary pressure resistance, achieving a balance between ease of manufacture and mechanical strength requirements.
