Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure air guns for cleaning large areas are laborious and inefficient due to unstable hose swings, creating dead spots and uneven cleaning, and counterweights at the outlet end can cause random shaking.
Innovation Solution
A swing-type spray cleaning gun with multiple weight blocks inside and outside the pipe, including a heavier end weight block, to provide stable centrifugal force and even swing amplitude, enhanced by a buffer weight block and adjustable swing amplitude mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a counterweight is added at the outlet end of the hose to increase centrifugal force, then the spray range and cleaning coverage are improved, but the hose becomes unstable and shakes randomly due to mismatch between gas pressure and center of gravity
Solution Approach 1:
The single counterweight at the outlet end is segmented into multiple weight blocks distributed along the hose length. This segmentation allows the center of gravity to be positioned optimally within the hose, balancing the centrifugal force generation with hose stability during swinging motion.
Solution Approach 2:
Different sections of the hose are assigned different weight characteristics. Weight blocks are strategically placed at specific locations along the hose to create local weight adjustments, ensuring that the center of gravity is positioned to maintain stability while still generating sufficient centrifugal force for wide spray coverage.
2Productivity
If the hose is made flexible to enable swinging motion for expanded spray range, then the cleaning efficiency is improved, but the swing becomes unstable creating dead spots and uneven cleaning
Solution Approach 1:
The flexible hose is divided into functional sections by placing weight blocks at intervals. This segmentation provides structural guidance for the swinging motion, ensuring uniform rotation and preventing erratic movements that create dead spots, while maintaining the flexibility needed for expanded spray range.
Solution Approach 2:
The physical parameters of the hose system are modified by adding weight blocks that change the mass distribution and moment of inertia. This adjustment stabilizes the swinging motion parameters, ensuring consistent rotation speed and trajectory, which eliminates dead spots and achieves uniform cleaning coverage.
3Stability of the object's composition
If multiple weight blocks are added inside and outside the pipe including a heavier end weight block, then the swing stability is improved, but the device complexity increases
Solution Approach 1:
The complex weight distribution requirement is segmented into discrete, standardized weight blocks placed at specific locations. This segmentation makes the complex stability requirement manageable through simple, repeatable components rather than a single complex counterweight mechanism.
Solution Approach 2:
Multiple weight blocks serve as counterweights distributed along the hose to balance the system's center of gravity. The heavier end weight block provides the necessary counterbalancing effect to stabilize the spray pipe during swinging, while the distributed arrangement simplifies the overall configuration compared to a single large counterweight.

AI summary
A swing-type spray cleaning gun includes a gas supplier and a sprinkler. The sprinkler includes an adapter pipe assembly fixed to the gas supplier, a fixed outer pipe fixedly connected to the adapter pipe assembly, a spray pipe and a swing amplitude adjustment assembly. The fixed outer pipe has a stroke limiting hole. The spray pipe includes an elastic pipe body fixed to the adapter pipe assembly, a plurality of weight blocks in the pipe set inside the fixed outer pipe and fixed on the elastic pipe body, and an end weight block. The elastic pipe body extends to the outside of the fixed outer pipe. The end weight block is sleeved and mounted outside the fixed outer pipe and fixed on the elastic pipe body. The swing amplitude adjustment assembly is movably mounted on the spray pipe to selectively adjust the swing amplitude of the spray pipe.
