Multi-part Flushing Connector for Brake Salt Residue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Brake devices on boat trailers suffer from reduced braking performance and increased corrosion due to salt residues forming a salt crust after exposure to saltwater, requiring an efficient and simple method to flush out these residues without modifying the brake plate with threaded holes.
Innovation Solution
A multi-part flushing connector system comprising assembled parts with convex grooves and contact surfaces that can be easily connected to the brake plate's inspection hole, allowing for the introduction and discharge of fresh water to clear salt residues, featuring a tubular connection point and interrupted fastening groove for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push-in fitting is screwed into threaded holes in the brake plate to enable flushing, then the brake interior can be rinsed with fresh water to remove salt residues, but the brake plate requires additional threaded holes which increase manufacturing complexity and modify the original brake structure
Solution Approach 1:
The patent introduces an intermediary flushing connection piece that connects to the existing inspection hole in the brake plate, rather than modifying the brake plate directly. This intermediary device includes a connection piece with a groove that engages with the inspection hole opening, allowing water flushing without altering the brake plate structure. The connection piece serves as a mediator between the flushing system and the brake interior.
Solution Approach 2:
The patent extracts the flushing connection function from the brake plate itself and places it in a separate, removable connection piece. This allows the flushing capability to be added without modifying the brake plate, as the connection piece can be attached to the existing inspection hole opening and removed when not needed.
2Ease of manufacture
If the brake plate is modified with threaded holes for flushing connections, then salt residues can be removed effectively, but the modification increases manufacturing cost and complexity
Solution Approach 1:
The connection piece acts as an intermediary that provides flushing access through the existing inspection hole without requiring modifications to the brake plate. This maintains the original manufacturing process for the brake plate while still enabling effective removal of salt residues through the intermediary flushing connection.
3Ease of operation
If a multi-part flushing connection piece is used to engage with the inspection hole, then connection and disconnection becomes simple without brake plate modifications, but the connection piece structure becomes more complex with multiple parts and grooves
Solution Approach 1:
The flushing connection system is segmented into multiple parts: the connection piece with engagement groove, and the inspection hole in the brake plate. This segmentation allows the connection piece to be a separate, simple component that engages with the existing inspection hole, making connection and disconnection easy without complex integration into the brake plate structure.

AI summary
The connector (200) has flushing connector parts (100) extending along entire longitudinal axis of a recess. Each connector part comprises two contact surfaces in a terminal portion. A contact surface of each connector part is arranged in contact with the contact surface of another connector part such that the composite connector parts form the connector. A fastening groove and a tubular terminal are formed by respective grooves of the connector parts. The fastening groove is formed as a circulating groove around the connector. The connector parts are made of metal or plastic. An independent claim is also included for a brake.
