Banjo Fitting Seal Assembly With Orientation Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing devices for hydraulic and pneumatic connections, particularly banjo fittings, often fail to provide sufficient sealing due to incorrect assembly, leading to fluid leaks at high-pressure connections.
Innovation Solution
A sealing device comprising a first sealing means and a second sealing means joined by straps with an orientation indicator, such as an arrow or RFID tag, to ensure correct installation orientation and prevent misassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional washers or sealing devices are used at hydraulic connections, then the structure is simple, but sufficient sealing is not provided especially with banjo fittings
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated sealing device that includes both a first sealing means (for the first fluid connection) and a second sealing means (for the second fluid connection), joined by a bridge element. This merging approach provides comprehensive sealing for banjo fittings while maintaining structural simplicity, resolving the contradiction between sealing reliability and device complexity.
2Ease of operation
If no orientation indicator is provided on the sealing device, then the device structure is simpler, but wrong assembly of two different sealing means occurs leading to leaks
Solution Approach 1:
The patent incorporates visual orientation indicators (such as color coding or directional markings) on the sealing device components. These indicators provide immediate visual feedback to operators during installation, ensuring correct assembly orientation without adding mechanical complexity. This resolves the contradiction between ease of operation and device complexity by using optical rather than mechanical means.
3Reliability
If multiple sealing means are used without orientation indicators, then manufacturing is simpler, but wrong assembly leads to fluid leaks at high-pressure connections
Solution Approach 1:
The patent incorporates orientation indicators and identification features during the manufacturing process itself, rather than requiring additional assembly steps or complex manufacturing procedures. The indicators are integrated into the molding or fabrication process, allowing for simple manufacturing while ensuring correct assembly and preventing leaks through proper orientation of the multiple sealing means.
