Air-Driven Alternator Integrates Power Generation in Waterblasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waterblasting systems face challenges due to the exposure of electrical cables to harsh environments, leading to maintenance and operational issues, as they are more susceptible to damage from heavy equipment traffic, standing water, and high-pressure water jets compared to water hoses and air hoses.
Innovation Solution
Incorporating an alternator within the air preparation and power unit of the waterblasting system, which generates electric power from compressed air, eliminating the need for external power sources and reducing the length of exposed electrical cables by integrating the power source and alternator into a single unit within the air supply device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical cables are made long to connect separate components, then the system can operate with separate components, but the cables are exposed to harsh environments causing damage and maintenance issues
Solution Approach 1:
The patent combines the air compressor, alternator, and electrical power source into a single integrated air supply device. This merging eliminates the need for long external electrical cables connecting separate components, thereby protecting electrical connections from harsh environments while maintaining system functionality.
Solution Approach 2:
The alternator acts as an intermediary device that converts mechanical energy from the air compressor into electrical energy. This intermediary mechanism allows the system to generate power on-site without requiring external electrical cables, solving the problem of cable exposure to harsh conditions.
2Adaptability or versatility
If external power sources are used, then the system can operate with separate power supply, but electrical cables are exposed to harsh environments leading to safety and maintenance issues
Solution Approach 1:
The system becomes self-sufficient by incorporating an alternator that generates electrical power from the mechanical energy of the air compressor. This self-service approach eliminates the need for external power sources and long electrical cables, thereby protecting the system from environmental harmful factors while maintaining operational versatility.
3Reliability
If electrical cables are kept short to reduce exposure, then cable protection is improved, but separate components require complex cable management
Solution Approach 1:
By merging the air compressor and alternator into a single integrated unit, the patent eliminates the need for cable management between separate components. The electrical connections are contained within the integrated device, simultaneously improving reliability by reducing exposure and simplifying the overall system complexity.
