Dishwasher Detergent Dosing Housing With Integrated Expansion Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers require complex and costly pressure-regulating mechanisms and separate openings for expansion and detergent dosing systems, complicating their structural design and increasing production costs.
Innovation Solution
A water-bearing household appliance with an integrated detergent dosing system that creates an expansion opening between the washing compartment and the environment, eliminating the need for separate openings and simplifying the structural design by incorporating the detergent dosing system adjacent to the washing compartment, allowing for a more cost-effective and efficient manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate pressure-regulating means and opening are provided in the washing compartment, then pressure equalization and expansion relief are ensured, but the structural design becomes more complex and production costs increase
Solution Approach 1:
The patent combines the pressure-regulating function with the detergent dosing system by integrating an expansion opening directly into the dosing system housing. This merging eliminates the need for separate pressure relief components and openings in the washing compartment, thereby simplifying the overall structural design while maintaining reliable pressure equalization functionality.
2Adaptability or versatility
If separate openings are provided for pressure regulation and detergent dosing, then functional requirements are met, but the number of sealing points increases and production steps are multiplied
Solution Approach 1:
The detergent dosing system housing is designed to incorporate both the detergent dispensing function and the expansion opening function within a single integrated structure. This reduces the total number of separate openings and sealing points required in the washing compartment, thereby reducing production steps and simplifying manufacturing processes while still meeting all functional requirements for both detergent dosing and pressure regulation.
3Device complexity
If the detergent dosing system is integrated into the washing compartment, then structural simplification is achieved, but the dosing system must also serve as the expansion opening pathway
Solution Approach 1:
The detergent dosing system housing is designed as a multi-functional component that simultaneously serves as the detergent dispensing mechanism and as the pathway for expansion opening. The housing structure includes an integrated expansion opening that allows pressure equalization while maintaining the detergent dosing functionality, thereby achieving structural simplification without compromising functional versatility.
