Pivoting Line Retainer for Fast Motor Vehicle Line Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for lines in motor vehicles are either time-intensive and costly due to the need for multiple securing elements or difficult to assemble due to issues with line diameter and positioning.
Innovation Solution
A retention member with pivotably connected retention elements that form a through-opening for the line, allowing for easy assembly and secure fastening with a single securing element, utilizing a joint and line guides with semi-circular profiles to ensure precise positioning and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple securing elements (engagement hooks and screw) are used to fasten the line, then the fastening is secure and reliable, but the assembly process becomes time-intensive and cost-intensive
Solution Approach 1:
The patent combines multiple securing functions into a single retention member that integrates both the engagement hook and screw mounting capabilities. The retention member has a first engagement hook for securing the line and a second engagement hook for mounting to the vehicle body, eliminating the need for separate securing elements and reducing assembly steps while maintaining fastening reliability
Solution Approach 2:
The retention member is designed as a multi-functional component that simultaneously performs line engagement, positioning, and securing functions. It combines the line retention function with the mounting function to the vehicle body, allowing a single component to replace multiple separate securing elements and simplify the assembly process
2Ease of operation
If a through-opening is provided in the carrier element for line passage, then the line can be guided through, but if the opening diameter is similar to line diameter, guiding becomes difficult and time-intensive
Solution Approach 1:
The retention member is divided into separate functional elements including the retention body with through-opening and the engagement hooks. This segmentation allows the through-opening to be optimized for easy line passage while the engagement hooks provide secure fastening, resolving the contradiction between ease of line guiding and secure retention
3Manufacturing precision
If the through-opening diameter is significantly smaller than the line diameter, then the line positioning is defined and pull compensation is ensured, but guiding the line through becomes difficult
Solution Approach 1:
The retention member acts as an intermediary component between the line and the vehicle body. The through-opening in the retention body provides a guided path for the line, while the engagement hooks secure the line in position. This intermediary structure enables both easy line guiding and precise positioning without requiring the opening diameter to be tightly constrained

AI summary
A retention member for holding a line includes first and second retention elements connected to one another such that the retention member is pivotable between a retaining position, in which the first and second retention elements abut one another, and a fitting position, in which the first and second retention elements are spaced apart. The first and second retention elements each have a line guide, and in the retaining position the line guides together form a through-opening for the line. The first retention element has an insertion element which can be disposed in a receptacle of a fastening arrangement, which receptacle is fixed to the vehicle, and the insertion element comprises a first through-hole. The second retention element has a second through-hole which is aligned with the first through-hole in the retaining position. The receptacle fixed to the vehicle comprises a recess. If the retention member is disposed in the recess fixed to the vehicle, the first through-hole, the second through-hole and the recess are aligned and a securing element is disposed therein, securing the retention member in the retaining position and on the receptacle fixed to the vehicle.
