Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic actuation systems in machine tools require two separate compressed air lines for piston extraction and withdrawal, leading to increased costs and system dimensions, compromising efficiency and industrial costs.
Innovation Solution
A pneumatic actuation system utilizing a single compressed air supply line, where the piston-cylinder assembly includes a silencer filter, and pressure control units manage air flow to lower and raise the piston through pressure adjustments, allowing for both operations with a single air line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate compressed air lines are used for piston extraction and withdrawal, then reliable operation is achieved, but system cost and dimensions increase
Solution Approach 1:
The patent combines two separate pneumatic circuits (extraction and withdrawal) into a single integrated circuit. The piston-cylinder assembly uses one compressed air line that serves both functions: supplying air to the first chamber for extraction and to the second chamber for withdrawal, eliminating the need for separate air lines and reducing system complexity
Solution Approach 2:
The single compressed air line performs multiple functions by selectively supplying air to different chambers. The same air line serves both extraction and withdrawal operations, making the pneumatic system multi-functional and reducing overall system complexity while maintaining reliable operation
2Reliability
If two separate compressed air lines are used for piston extraction and withdrawal, then complete pneumatic control is achieved, but overall system dimensions increase
Solution Approach 1:
The patent merges two separate pneumatic circuits into one integrated system. The single compressed air line replaces two separate lines, and the piston-cylinder assembly with two chambers shares a common air supply, reducing the overall volume required for the pneumatic system while maintaining complete control over piston extraction and withdrawal
3Device complexity
If a single compressed air line is used, then system cost and dimensions are reduced, but control precision must be maintained
Solution Approach 1:
The patent applies local quality by creating different pressure conditions in different chambers of the piston-cylinder assembly. The first chamber receives compressed air for extraction while the second chamber receives compressed air for withdrawal, allowing precise local control of piston position despite using a single overall air supply line
Solution Approach 2:
The system maintains control precision by changing pressure parameters selectively in different chambers. By controlling the pressure in the first and second chambers independently through the single air line, the system achieves precise piston position control while reducing overall system complexity
