Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for T-shaped profile hoses with polymer material face challenges in achieving precise alignment and tolerance compensation, leading to canting issues and increased costs due to complex tolerances and labor-intensive fixation methods.
Innovation Solution
A fastening element made of a one-part sheet metal construction with locking teeth that penetrates the polymer material of the T-shaped profile hose, providing a form-fit and friction-fit connection, allowing for precise alignment and reduced tolerance chain, thereby simplifying the connection process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional flange connections with metallic end pieces are used to connect profile hoses, then the connection strength is improved, but the alignment precision deteriorates due to tolerance accumulation and canting at transition points
Solution Approach 1:
The patent replaces the traditional mechanical flange connection system with a setting device that directly sets fastening elements from within the profile hose, eliminating the need for separate metallic end pieces and flange connections. This substitution resolves the contradiction by achieving both strong fixation and precise alignment through the integrated setting mechanism.
Solution Approach 2:
The patent merges the functions of the profile hose, fastening elements, and setting device into an integrated system. The fastening elements are set directly from within the profile hose through the setting device, combining multiple components into a unified structure that eliminates tolerance accumulation between separate parts.
2Reliability
If metallic end pieces are glued on profile hoses for fixation, then the connection reliability is improved, but the manufacturing complexity and cost increase due to precision requirements
Solution Approach 1:
The setting device is inserted through the profile hose and sets the fastening elements from within, allowing the system to self-fixate without requiring external gluing operations or complex assembly procedures. The profile hose itself serves as the setting device housing, eliminating the need for separate fixation mechanisms.
3Strength
If traditional connection methods with multiple components are used, then the connection strength is improved, but the labor costs and processing time increase
Solution Approach 1:
The patent combines the setting device with the profile hose structure, where the profile hose acts as the housing for the setting device. This merging eliminates multiple separate components and simplifies the connection process, achieving both strong fixation and improved productivity.
Solution Approach 2:
The profile hose serves multiple functions: it acts as both the structural component and the housing for the setting device. The setting device can set multiple fastening elements sequentially, providing multi-functionality that reduces processing time and labor costs while maintaining connection strength.
