Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressed air tools with traditional silencers, such as cotton or copper silencers, face inefficiencies due to oil jamming the silencing elements, leading to non-smooth exhaust emission and reduced air motor performance.
Innovation Solution
A compressed air tool design featuring a silencer structure with two walls having long slits, where one wall is positioned before the other, forming a channel for exhaust flow, and an outer cover with a countersink and side hole for lateral emission, allowing smooth exhaust emission without the need for traditional silencing materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional silencing cotton or copper silencer is used in the air exhaust channel, then noise reduction effect is achieved, but oil in the exhaust jams the silencing elements causing non-smooth exhaust emission and reduced air motor efficiency
Solution Approach 1:
The invention removes traditional silencing materials (cotton or copper particles) from the air exhaust channel and replaces them with a silencer structure consisting of two walls with misaligned long slits. This extraction eliminates the problem of oil jamming while maintaining noise reduction functionality through the geometric design of the slits and channels.
Solution Approach 2:
Instead of using actual porous materials like cotton or copper particles that get clogged, the invention creates a porous-like flow path through misaligned slits in two walls. The exhaust must pass through multiple slit openings and navigate channels, providing noise reduction similar to porous materials without the clogging issue.
2Object-affected harmful factors
If silencing cotton is arranged between inner and outer pipes, then noise is reduced through buffered air flow, but the structure becomes complex and occupies space
Solution Approach 1:
The silencer is divided into two separate walls with multiple long slits rather than using a single complex structure or packed materials. Each wall independently contributes to noise reduction, and the segmented design simplifies manufacturing and assembly while reducing overall structural complexity.
Solution Approach 2:
The invention transitions from a three-dimensional packed structure (cotton between pipes) to a two-dimensional surface design (slits on wall surfaces). This dimensional reduction simplifies the structure while maintaining the noise reduction function through the pattern and orientation of the slits.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures efficient exhaust emission and prevents air motor inefficiencies by directing exhaust flow through misaligned slits and channels, effectively reducing noise and maintaining tool performance.
Implementation Method 1
the air flow of the exhaust is buffered to become weaker
Implementation Method 2
the exhaust is then emitted via the outer pipe
Implementation Method 3
The long slits of one of the two walls are misaligned with and do not face toward that of the other of two walls

AI summary
The present disclosure illustrates a compressed air tool having a silencer structure. A silencing element and an outer cover are disposed in an air exhaust channel of a main body of the compressed air tool. The silencing element has two walls and a channel. The two walls both have long slits, the long slits of the two walls are misaligned and not directly faced with each other. After the exhaust is inputted via the long slits of one of the two walls, the exhaust is flowed through the channel and emitted to the outside via the long slits of other of the two walls. Therefore, the air flow of the exhaust can be weakened, and the exhaust is then entered the countersink of the outer cover and emitted from the side hole, whereby the effect of silencing and reducing the noise caused by the emitted exhaust can be achieved.
