Emergency Brake Cylinder Non-Detachable Connection Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency brake cylinder connections in heavy vehicles are either detachable or require complex and costly zinc-based coatings, leading to potential safety hazards and environmental concerns due to unauthorized interventions and high material usage.
Innovation Solution
A non-detachable body connection method using a connection ring that enables the secure coupling of emergency and service chambers with different dimensions, eliminating the need for screws and bolts, and reducing zinc usage by coating only the connection ring, which is shaped using a mould or roll form spool for enhanced corrosion resistance and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable connection methods (screws and bolts) are used to connect emergency and service chambers, then ease of assembly and disassembly is improved, but safety is worsened due to potential unauthorized interventions and improper reassembly
Solution Approach 1:
The connection system is divided into two parts: a connection ring with protrusions that fits into corresponding sockets on the chambers. This segmentation allows the connection to be made in two stages - insertion followed by locking - preventing improper assembly while maintaining ease of operation
Solution Approach 2:
The connection ring acts as an intermediary element between the emergency chamber and service chamber. It mediates the connection by providing a standardized interface with protrusions and sockets, ensuring proper alignment and preventing unauthorized interventions through its locking mechanism
2Reliability
If zinc-based coatings are applied to the entire body to prevent corrosion, then corrosion resistance is improved, but material costs and environmental impact are worsened due to high zinc usage
Solution Approach 1:
Instead of applying zinc-based coatings uniformly across the entire body, the coating is applied locally only to the connection ring where corrosion resistance is most critical. This local quality approach maintains adequate protection at the connection interface while significantly reducing overall material usage and environmental impact
3Reliability
If complex connection systems with multiple components are used to ensure secure connection, then reliability is improved, but device complexity is worsened
Solution Approach 1:
Multiple connection functions are merged into a single connection ring component. The ring integrates protrusions for engagement, locking features for security, and positioning elements for alignment, all in one piece. This merging reduces the number of separate components while maintaining connection security and reducing overall system complexity
4Ease of operation
If standardized connection systems are used to simplify installation, then ease of operation is improved, but adaptability is worsened when dealing with chambers of different dimensions
Solution Approach 1:
The connection ring is designed with universal characteristics - the protrusions and sockets are configured to accommodate chambers of different dimensions. The standardized interface allows the same connection ring design to be used across various chamber sizes, maintaining both installation simplicity and adaptability through scalable geometry

AI summary
The invention is related to a non detachable body connection with a connection ring which enables the non detachable connection of the upper body located at the service part of the emergency brake cylinders used in the airbrake systems of heavy weight vehicles and the lower body parts located at the emergency section by using an additional piece during the coupling with adapter plate.
