Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in effectively cleaning and rinsing the internal surfaces of complex, enclosed cavities, such as those found in nuclear particle accelerators, without contaminating controlled environments.
Innovation Solution
A vertical high-pressure rinse machine with a motor and gearbox to rotate a spray wand, mounted on a rail system, allowing for vertical movement and enclosure creation around the spray wand to maintain a water-tight environment, enabling cleaning of internal surfaces without disassembly and minimizing contamination risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning equipment is inserted into a clean room environment, then cleaning of internal surfaces can be performed, but contamination of the clean room environment occurs
Solution Approach 1:
The spray wand assembly is inserted through a sealed access port in the enclosure wall, with the spray tip extending into the cavity while the motor and gearbox remain outside the clean room environment. This nested configuration allows the cleaning function to reach inside the cavity without introducing external contamination sources into the clean room.
Solution Approach 2:
A water-tight enclosure with sealed access ports serves as an intermediary barrier between the cleaning equipment and the clean room environment. The enclosure contains the motor, gearbox, and spray mechanism, while allowing the spray function to reach the cavity through sealed interfaces, preventing contamination transfer.
2Device complexity
If the spray wand is fixed in position, then the structure is simpler, but it cannot effectively clean different positions of the cavity
Solution Approach 1:
The spray wand is made dynamically adjustable through a positioning mechanism that allows it to be moved to different angles and positions. The spray wand can be rotated and tilted to reach various surfaces within the cavity, transforming a static structure into a dynamic one that adapts to different cleaning requirements while maintaining relative structural simplicity.
Solution Approach 2:
The spray mechanism is divided into separate functional components: the motor and gearbox housed in the enclosure, the spray wand as a separate adjustable element, and the spray tip. This segmentation allows the spray wand to be independently positioned and angled without affecting the motor assembly, enabling flexible cleaning coverage with manageable structural complexity.
3Ease of operation
If the enclosure is open for access, then loading and unloading is easier, but water-tight sealing is compromised
Solution Approach 1:
The spray wand is extracted through a sealed access port rather than having the entire enclosure opened. The access port remains closed during operation, with only the spray tip extending through the seal to deliver water into the cavity. This extraction approach maintains the water-tight integrity of the enclosure while providing the necessary access function.
Solution Approach 2:
Flexible seals and gaskets are used at the access ports and connection interfaces to maintain water-tight sealing while allowing for thermal expansion, vibration, and slight misalignments. The flexible sealing elements accommodate operational movements without compromising the water-tight barrier between the enclosure and the clean room environment.
