Double-Hose Strain Relief Structure for Leak-Safe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-bearing household appliances, such as dishwashers and washing machines, face challenges in easily installing strain relief devices for double hoses to prevent damage from hose pulling and efficiently manage leaking water.
Innovation Solution
A two-part strain relief device with plate-shaped carriers and integrated receptacles for each hose, designed for easy installation and compactness, where the first and third receptacles enclose the first hose, and the second and fourth receptacles enclose the second hose, allowing for effective strain relief and water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strain relief device is installed to prevent hose damage from pulling, then hose protection and operational safety are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The strain relief device is divided into two separate carriers: a first carrier for the first hose and a second carrier for the second hose. Each carrier independently secures its respective hose, preventing mutual interference and simplifying the overall structure while maintaining protection effectiveness for both hoses
Solution Approach 2:
The second hose is arranged inside the first hose, forming a nested configuration. The strain relief device accommodates both hoses in this nested arrangement, with the first carrier securing the outer first hose and the second carrier securing the inner second hose, optimizing space utilization while providing strain relief
2Volume of moving object
If a strain relief device is designed to be compact, then space utilization is improved, but installation ease and accessibility may worsen
Solution Approach 1:
By separating the strain relief device into two independent carriers mounted at different locations, each carrier can be compact in size while the overall device provides distributed protection. The first carrier is mounted at a first location and the second carrier at a second location, allowing compact individual units that are easy to install separately
Solution Approach 2:
The two carriers are arranged in different spatial dimensions/locations rather than stacking one on top of the other. This dimensional distribution reduces the volume footprint while maintaining accessibility for installation and maintenance of each carrier independently
