Multi-Connection Device for Hydraulic Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-connection devices for hydraulic or electric lines are bulky, complex, and costly due to the need for additional hooking systems and centring pins, which also create assembly difficulties and potential interference with mechanical operations.
Innovation Solution
A simplified multi-connection device design that integrates hooking and centring functions within a compact structure, using a fixed plate with axially movable hooking pins and a movable plate with a T-shaped groove for stable coupling without protruding parts, reducing volume and production complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional hooking systems and centring pins are used to ensure stable connection, then connection reliability is improved, but device volume and structural complexity increase
Solution Approach 1:
The patent merges the hooking system and centring pins into a single integrated component. The hooking element features a T-shaped profile where the vertical portion provides centring function and the horizontal portion provides hooking function, eliminating the need for separate components and reducing overall device complexity while maintaining connection reliability
Solution Approach 2:
The T-shaped hooking element serves multiple functions simultaneously: it acts as both a centring mechanism and a hooking system. This multi-functional design reduces the number of components needed while ensuring stable and accurate connection between the fixed and movable parts
2Device complexity
If hooking system is integrated within centring pins, then device structure is simplified, but assembly or positioning difficulties occur
Solution Approach 1:
The T-shaped hooking element is divided into two functional segments: the vertical portion that provides centring and the horizontal portion that provides hooking. This segmentation allows each part to perform its specific function effectively while maintaining a simple integrated structure that is easy to manufacture and assemble
3Adaptability or versatility
If traditional multi-connection devices are used, then connection functionality is achieved, but protruding parts interfere with mechanical operations
Solution Approach 1:
The patent extracts the protruding elements from the design by making the hooking element recessed within the fixed part. The T-shaped hooking element is positioned such that it does not protrude outward, eliminating interference with mechanical operations while maintaining full connection functionality
Solution Approach 2:
The hooking element is designed to engage in a recessed manner rather than protruding outward. By changing the spatial arrangement from external protrusion to internal recessed engagement, the device maintains connection functionality without creating harmful protrusions that would interfere with mechanical operations
