Heated Hose Fixing Layout for Cut-to-Length Conductor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing heatable hoses require the removal of an outer layer to expose electrical conductors, which can damage the heating conductors and pressure carrier, and involves cutting and unwinding of endless hoses, making the process cumbersome and prone to conductor damage.
Innovation Solution
A method where a fixing element is applied to a base body with electrical conductors, with interruptions at specific positions, allowing the hose to be cut to length during production and eliminating the need to remove the outer layer, thereby simplifying the process and preventing conductor damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer layer is removed to expose electrical conductors, then the conductors become accessible for connection, but the heating conductors and pressure carrier are damaged
Solution Approach 1:
The hose is divided into a first hose end and a second hose end by interrupting the outer layer at specific positions, allowing selective access to conductors at one end while preserving the other end's integrity
Solution Approach 2:
The outer layer is selectively removed only at the first hose end to expose the electrical conductors where needed, while the second hose end retains its intact outer layer and pressure carrier structure
2Length of moving object
If the hose is cut to length after production, then the desired length is achieved, but the process becomes cumbersome and conductors are damaged
Solution Approach 1:
The hose is cut to the desired length during the production process before the outer layer is applied, so that subsequent handling and installation only require simple outer layer removal rather than cutting and unwinding operations
3Stability of the object's composition
If the outer layer is continuously applied without interruption, then the hose structure is complete, but subsequent conductor access requires damaging removal
Solution Approach 1:
The outer layer application is segmented into interrupted sections, with gaps positioned to expose electrical conductors at the first hose end while maintaining structural completeness elsewhere
Solution Approach 2:
The outer layer is selectively applied or removed at different locations along the hose, creating locally different structures: intact outer layer at the second end for structural stability, and exposed conductors at the first end for electrical connection
