Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatic rust-removing tools face inefficiencies due to bending of metal needles under lateral forces, requiring frequent replacement of needles of different lengths to adapt to various operational scenarios, which is inconvenient and costly.
Innovation Solution
A pneumatic rust-removing tool with a slide sleeve mechanism that allows adjustable exposure lengths of rust-removing needles by moving the slide sleeve relative to the main body, ensuring effective force transmission and eliminating the need for multiple tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If longer rust-removing needles are used, then rust-removing coverage is improved, but needle bending occurs under lateral forces reducing effectiveness
Solution Approach 1:
The invention introduces a movable support block that can be adjusted along the guide groove to different positions. This dynamic adjustment allows the support block to provide lateral support to the needle at optimal positions, enabling the needle to maintain both sufficient length for coverage and stability against bending forces during operation.
2Reliability
If shorter rust-removing needles are used, then needle stability is improved, but rust-removing coverage is reduced
Solution Approach 1:
The support block acts as an intermediary element between the needle and the tool body. It provides lateral support to the needle at adjustable positions along the guide groove, effectively extending the functional length of stable needle operation without requiring physically shorter needles. This mediator enables long needles to operate stably by providing intermediate support.
3Adaptability or versatility
If multiple tools with different needle lengths are purchased, then adaptability to different scenarios is improved, but cost and portability are worsened
Solution Approach 1:
The invention makes a single rust-removing tool universal by adding the adjustable support block mechanism. The support block can be positioned at different locations along the guide groove to accommodate different needle lengths and operational scenarios. This single tool with adjustable support replaces the need for multiple fixed-tools, achieving scenario adaptability while reducing tool quantity and improving portability.
4Adaptability or versatility
If frequent needle replacement is performed, then adaptability to different scenarios is improved, but time efficiency is reduced
Solution Approach 1:
Instead of replacing needles or tools to adapt to different scenarios, the invention enables dynamic adjustment of the support block position along the guide groove. This allows rapid adaptation to different operational conditions by simply moving the support block to appropriate positions, eliminating the time-consuming process of needle or tool replacement while maintaining scenario adaptability.

Implementation Method 1
a spring (28) disposed in the chamber (12)
Implementation Method 2
high-pressure gas to drive an internal impact block. This impact block then strikes a plurality of rust-removing needles to move forward
Implementation Method 3
the rust-removing needle, which is made of metal material, has a certain elasticity

AI summary
A pneumatic rust-removing tool includes a main body having a chamber and an opening at a front end of the chamber, an impact block reciprocatingly moveable back and forth in the chamber, a spring disposed in the chamber, a mount disposed in the chamber and located between the impact block and the spring, rust-removing needles disposed with the mount and extending through the opening, and a slide sleeve disposed to the main body in a way that the slide sleeve is moveable back and forth relative to the main body. The slide sleeve is provided with a plurality of through holes, through which the rust-removing needles extend respectively. As a result, the pneumatic rust-removing tool can quickly adjust the exposed lengths of the rust-removing needles to adapt to different operational scenarios, thereby enhancing work efficiency and reducing the economic burden on the user.
