Adjustable Plastic Water Guides for Variable Inlet Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The variety of variants in plastic water pipes for sanitary fittings leads to high manufacturing costs due to the need for adapted pipe lengths, which complicates the assembly and increases production expenses.
Innovation Solution
A sanitary fitting design featuring adjustable plastic water guides for hot and cold water channels, allowing them to be adapted to different distances between inlets without requiring multiple variants of water guides, thus reducing the complexity and cost of manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapted plastic water guides are used for different distances between hot and cold water inlets, then the sanitary fitting can be adapted to various building connections, but the variety of variants increases and manufacturing costs rise
Solution Approach 1:
The plastic water guide is designed with a universal adjustment mechanism that allows a single guide design to accommodate multiple distances between hot and cold water inlets. The guide can be adjusted positionally to fit different building connections, eliminating the need for multiple specialized guide variants and reducing manufacturing complexity while maintaining adaptability.
2Adaptability or versatility
If multiple variants of plastic water guides are manufactured for different distances, then various building connections can be accommodated, but production expenses increase
Solution Approach 1:
Instead of manufacturing multiple variants of plastic water guides with different geometries, the invention changes the positional parameters of a single guide design. The guide can be installed at different positions or orientations to accommodate various inlet distances, allowing manufacturers to produce only one type of guide while still serving multiple installation scenarios, thereby reducing production expenses.
3Adaptability or versatility
If multiple variants of plastic water guides are produced, then different inlet distances can be accommodated, but assembly complexity increases
Solution Approach 1:
The plastic water guide incorporates dynamic adjustment capabilities, allowing installers to position and secure the guide at different locations along the fitting body depending on the specific inlet distance. This dynamic positioning feature simplifies assembly by providing flexibility during installation rather than requiring pre-selected variants, thereby reducing assembly complexity while maintaining adaptability to various inlet distances.
