Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick couplings for pressure media feeds in hydraulic systems are cumbersome to operate, require excessive force, and result in large, heavy designs due to lateral forces and the need for wide engagement slots, making them inefficient and costly to manufacture.
Innovation Solution
A quick coupling design featuring a movably guided mounting frame that absorbs forces, allowing the support plate to be connected to the mounting frame and eliminating the need for manual holding, with an eccentric member for compact force transmission and a self-locking mechanism for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If curved engagement slots are used to close the quick coupling, then the coupling can be closed, but lateral forces are generated and the construction becomes more complex
Solution Approach 1:
The coupling mechanism is segmented into distinct functional components: the mounting frame with guide grooves for linear guidance, the support plate for mounting connections, and the actuating mechanism. This segmentation allows each component to perform its specific function without generating unnecessary lateral forces, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The mounting frame acts as an intermediary element between the base plate and support plate. It provides linear guidance through guide grooves and absorbs forces, mediating the coupling process to eliminate lateral forces while maintaining operational simplicity. This intermediary structure resolves the technical contradiction by decoupling the closure action from lateral force generation.
2Force
If the support plate is made heavy for large nominal widths, then it can handle large forces, but it requires manual holding during coupling
Solution Approach 1:
The mounting frame serves as a mediator that connects the support plate to the base plate while providing linear guidance through guide grooves. This intermediary structure allows heavy support plates to be properly guided and positioned without requiring manual holding, as the guide grooves constrain the movement path and eliminate the need for operator intervention during coupling.
Solution Approach 2:
The mounting frame is designed to be movably guided at the base plate, allowing dynamic adjustment and absorption of forces during the coupling process. This dynamic capability enables the system to handle heavy support plates with large force transmission capacity while maintaining ease of operation through automatic guidance and alignment.
3Force
If large forces are transmitted via collet chucks for large nominal widths, then the coupling can handle high loads, but the engagement slots and clamping levers must be made larger
Solution Approach 1:
The mounting frame acts as an intermediary that absorbs and transmits large forces between the base plate and support plate. By providing a robust intermediate structure with guide grooves and movable guidance, the system can transmit high loads without requiring oversized engagement slots and clamping levers, thus reducing the weight and size of moving components while maintaining force transmission capability.
Solution Approach 2:
The force transmission path is segmented into multiple components: the mounting frame absorbs forces, the guide grooves provide linear guidance, and the support plate provides mounting connections. This segmentation distributes the force transmission load across multiple elements rather than concentrating it in oversized engagement slots and clamping levers, reducing their required dimensions and weight.
4Device complexity
If the support plate is connected directly to the base plate, then the structure is simpler, but the support plate must be held manually during coupling
Solution Approach 1:
The mounting frame is introduced as an intermediary element between the base plate and support plate. While this adds a component to the structure, it eliminates the need for manual holding during coupling by providing linear guidance through guide grooves and movable guidance at the base plate. The added structural complexity is minimal compared to the significant improvement in ease of operation.
Solution Approach 2:
The mounting frame is designed with movable guidance at the base plate, allowing it to dynamically adjust and absorb forces during coupling. This dynamic capability enables the support plate to be properly positioned and connected without manual holding, resolving the contradiction between structural simplicity and ease of operation with minimal added complexity.

Function Achieved in This Case
The solution enables a secure, low-wear, and compact connection of pressure media feeds, simplifying operation and reducing the weight and size of the coupling while allowing for easy adaptation to various sizes and configurations.
Implementation Method 1
The mounting frame absorbs the large forces which arise on the connection of pressure media feeds
Implementation Method 2
The mounting frame is advantageously movable toward the base plate by the rotation of an eccentric member
Implementation Method 3
The mounting frame is advantageously movable toward the base plate by the rotation of an eccentric member. Such an eccentric member is an extremely compact and nevertheless stable possibility to absorb the high forces
Implementation Method 4
the compressive force is then advantageously generated between the rear part of the mounting frame and the base plate so that the support plate connected to the front part of the mounting frame is pulled toward the base plate by the mounting frame
Implementation Method 5
a mounting frame which is movably guided at the base plate and has means for the connection, or a connecting mechanism which comprises guide grooves, to the support plate
