Heatable Ceiling Boom for Vehicle Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heatable ceiling booms for high-pressure washing of vehicles face issues with low heat transfer efficiency and limited rotatability due to external heating jackets, which lead to high power consumption and operational vulnerabilities.
Innovation Solution
Guiding the heating cable inside the high-pressure hose for direct heat transfer and using a rotational power distributor to enable full 360° rotatability and secure power feeding, allowing for efficient heating and signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating jacket is connected to the outer circumference of the high-pressure hose, then the high-pressure medium can be heated to prevent freezing, but the heat transfer efficiency is poor and power consumption is high
Solution Approach 1:
The heating cable is nested inside the high-pressure hose, with the heating cable positioned within the inner circumference of the hose. This allows direct heat transfer from the heating cable to the high-pressure medium flowing through the hose, eliminating the need for an external heating jacket and significantly improving heat transfer efficiency while reducing power consumption.
2Temperature
If the heating jacket is powered through the rotating support arm, then heating can be provided, but the rotational angle is limited to no greater than 360° and power leads are susceptible to breakage
Solution Approach 1:
The heating cable is designed to be flexible and self-contained within the high-pressure hose, eliminating the need for external power leads that pass through the rotating support arm. The heating system becomes self-sufficient within the hose structure, allowing full rotatability without risk of power lead shearing or breakage.
3Loss of energy
If the heating cable is guided inside the high-pressure hose, then heat transfer efficiency is improved and power consumption is reduced, but the hose structure becomes more complex
Solution Approach 1:
The heating cable and high-pressure hose are merged into a single integrated structure, where the heating cable is positioned inside the hose rather than being a separate external component. This combining of functions reduces energy loss while the modular design keeps the overall structure manageable despite the added internal complexity.
