Dishwasher Hose Securing Clip for Tolerance-Robust Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose-securing devices integrated into dishwasher base tubs are not universally applicable and face issues with manufacturing tolerances, limiting flexibility and reliability in securing water-conducting lines like pump discharge hoses.
Innovation Solution
A securing element that attaches directly to the line end and connecting piece, providing a releasable locking connection and embracing the components in a form-locking manner, allowing for easy fitting and compensation of manufacturing-related tolerances, and is manufactured from a single piece of plastic for cost-effectiveness and ease of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hose-securing device is integrated into the base tub, then the hose can be secured against pulling out, but the device cannot be universally applied to all dishwasher types and has problems with manufacturing tolerances
Solution Approach 1:
The securing element is extracted from the base tub integration and made into a separate, independent component that can be universally applied to different dishwasher types and configurations, resolving the contradiction between securing reliability and universal applicability
Solution Approach 2:
The securing element is designed as a universal component that can be used across different dishwasher models and tub designs, eliminating the limitation of base tub-specific integration while maintaining effective hose securing functionality
2Reliability
If a hose-securing device is integrated into the base tub, then the hose can be secured, but manufacturing tolerances cause problems with component association
Solution Approach 1:
The securing element incorporates localized compensating features such as adjustment mechanisms or tolerance-absorbing design elements that accommodate manufacturing variations in the hose and connecting pieces, ensuring reliable securing despite tolerance deviations
Solution Approach 2:
The securing element design allows for parameter adjustments or variations that compensate for manufacturing tolerances, enabling reliable hose securing across different production batches and component variations
3Ease of manufacture
If the line end is pushed over the connecting piece, then the connection can be made, but the connection is not secure under operational loads
Solution Approach 1:
The securing element is installed beforehand on either the hose or connecting piece, creating a pre-positioned locking mechanism that ensures secure connection when components are assembled, maintaining both ease of assembly and connection security
Solution Approach 2:
The securing element acts as an intermediary component between the line end and connecting piece, providing a form-locking connection that enhances connection security while maintaining ease of assembly through simple clipping or snapping actions
4Reliability
If multiple separate components are used for securing, then the connection can be secured, but the manufacture and assembly become more complex
Solution Approach 1:
Multiple securing functions (clamping, locking, sealing, positioning) are merged into a single integrated securing element made of plastic, reducing the number of components while maintaining comprehensive connection security and simplifying assembly
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a universally applicable, easy-to-manufacture, and functionally reliable connection of water-conducting lines, ensuring secure positioning and sealing without excessive force, and accommodating different tub designs and high operational loads.
Implementation Method 1
The securing element is embodied as a half shell and/or as a securing bracket which can preferably be clipped on elastically
