Detachable Connecting Device Radial Bushing Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for internal combustion engine components, such as intake pipe housings and cylinder heads, are difficult to actuate at hard-to-reach locations due to the need for screw-based connections, which complicates the connection and disconnection process.
Innovation Solution
A detachable connecting device featuring a circumferentially closed bushing and bushing receptacle system that allows for force transmission through a rotary or plug-in movement, enabling easy insertion and removal of connecting elements, particularly at difficult-to-access locations, using bushings that can be inserted and removed radially, and providing a clamping connection for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based connections are used for detachable connecting devices, then reliable force transmission is achieved, but the device becomes difficult to actuate at hard-to-reach locations
Solution Approach 1:
The connecting element is designed to be insertable through a circumferential insertion opening perpendicular to the connecting axis, changing the dimension of access from axial (difficult) to radial (accessible). This allows the connecting element to be inserted from the side rather than from the end, solving the accessibility problem while maintaining secure connection through the bushing receptacle structure
Solution Approach 2:
The bushing acts as an intermediary component between the connecting element and the bushing receptacle. The bushing with its circumferential insertion opening mediates the connection by allowing the connecting element to pass through radially, enabling force transmission while facilitating easy insertion and removal at difficult-to-access locations
2Reliability
If complete removal of connecting elements is required for disassembly, then secure connection is ensured, but the complexity of disassembly increases
Solution Approach 1:
The connecting device is segmented into the bushing, bushing receptacle, and connecting element as separate components. The bushing with its circumferential insertion opening allows the connecting element to be inserted and retained independently, enabling simple disassembly by removing only the connecting element through the insertion opening without affecting other components
Solution Approach 2:
Instead of requiring complete removal of the connecting element for disassembly, the design inverts the approach by providing a circumferential insertion opening that allows the connecting element to be removed through the side of the bushing while the bushing itself remains in place, simplifying the disassembly process while maintaining connection security

AI summary
A detachable connecting device for connecting first and second functional components to each other has a connecting element arranged in a connecting element receptacle of the first functional component so as to be force-transmitting. A bushing that is circumferentially closed is arranged on the connecting element. A bushing receptacle is provided on the second functional component. The bushing together with the connecting element is arranged in the bushing receptacle for realizing force transmission between connecting element and second functional component. The bushing receptacle has a circumferential side relative to the connecting axis that is provided with an insertion section with insertion opening to insert the bushing from outside of the circumferential side into the interior of the bushing receptacle or to remove the bushing from the interior of the bushing receptacle through the circumferential side.
