Solution Overview
Problem
Existing hose line testing devices consume significant compressed air, are noisy, and require frequent maintenance, with intermittent filling processes that are time-consuming and inefficient.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a pre-filling pump is used to fill the hose line with test medium, then the hose line can be filled with test medium, but compressed air consumption increases significantly and noise level increases
Solution Approach 1:
The patent removes the pre-filling pump from the system entirely. Instead of using a pump to fill the hose line, the system uses a pressure accumulator pre-filled with test medium under pressure. When testing is required, the accumulator directly supplies the test medium to the hose line through controlled release, eliminating the need for compressed air-driven pumping and significantly reducing air consumption.
Solution Approach 2:
The patent employs a hydraulic pressure accumulator pre-charged with test medium under pressure. This hydraulic system replaces the pneumatic pre-filling pump, using stored hydraulic pressure rather than compressed air to deliver the test medium to the hose line, thereby eliminating compressed air consumption for the filling operation.
2Quantity of substance
If a pre-filling pump is used to fill the hose line, then the hose line can be filled, but the device generates significant noise
Solution Approach 1:
The patent removes the pre-filling pump that generates noise from the system. By replacing it with a pressure accumulator that passively releases pre-stored test medium, the source of mechanical noise is eliminated, resulting in significantly lower noise levels during the filling operation.
3Ease of operation
If single-acting pumps are used for filling, then the system can operate, but the filling process is intermittent and time-consuming
Solution Approach 1:
The patent implements continuous filling by using a pressure accumulator that maintains constant pressure and continuously supplies test medium to the hose line. This eliminates the intermittent operation of single-acting pumps, allowing the filling process to proceed without interruption and significantly increasing test effectiveness and productivity.
4Ease of operation
If single-acting pumps are used for filling, then the system can operate, but maintenance requirements increase
Solution Approach 1:
The patent removes the pre-filling pump entirely from the system, eliminating the mechanical components that require maintenance. By replacing the pump with a pressure accumulator system, there are no moving parts in the filling mechanism, thereby eliminating maintenance requirements for the filling operation.

AI summary
Hose line testing device has a induced pressure carrying system for filling a hose line (1) with a test medium, which is utilized for producing a testing pressure. The induced pressure carrying system has a pressure accumulator (7), which stands as a storage tank for the test medium, such that the filling of the hose line takes place with the effect of bias pressure. The accumulator has a filter set for cleaning the test medium.
