Grooved Damping Spring Automated Wire Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damping and spring arrangements with helically formed wire or cable require complex and non-automatable manual guidance through through-holes, resulting in punctiform fixation with high production effort.
Innovation Solution
A damping and spring arrangement where a wire or cable is wound around elongated metal end pieces with grooves, allowing for automated production with simple deformation of groove side areas to secure the windings, eliminating the need for additional fixing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wire or cable is guided through through-holes in complex manual manner, then fixation is achieved, but production effort increases and automation becomes difficult
Solution Approach 1:
The grooves are pre-formed in the end pieces before the wire or cable is installed. This preliminary preparation of the grooves allows the wire to be simply wound and pressed into place, eliminating the need for complex manual guidance through holes and enabling automated production.
Solution Approach 2:
The grooves act as an intermediary structure that facilitates the fixation of the wire or cable. Instead of directly guiding the wire through complex hole paths, the grooves provide a simple receptacle that can be easily formed and into which the wire can be automatically inserted and secured by pressing.
2Reliability
If cross-holes and clamping pieces are used for fixation, then wire turns are fixed, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates the need for separate clamping pieces and cross-holes by integrating the fixation function directly into the grooves formed in the end pieces. The grooves themselves provide the fixation mechanism through simple pressing, removing unnecessary components and simplifying the overall device structure.
Solution Approach 2:
The fixation function is merged with the groove structure. Instead of having separate fixation components (clamping pieces, cross-holes), the groove design combines the wire guidance and fixation functions into a single integrated feature that is formed directly in the end pieces.
3Ease of manufacture
If groove width corresponds to wire diameter, then fixation by pressing is facilitated, but manufacturing precision requirements increase
Solution Approach 1:
The groove width is designed to be slightly larger than the wire or cable diameter, creating a controlled clearance. This parameter adjustment allows the wire to be easily inserted and secured by pressing without requiring extremely tight manufacturing tolerances, while still providing adequate fixation security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick, automated, and secure fixation of the wire or cable, reducing production effort and ensuring stable damping and spring properties with symmetrical properties through opposite winding directions.
Implementation Method 1
Then only the groove side areas have to be deformed or pressed in such a way that the windings are fixed in the grooves

AI summary
The arrangement has two end pieces (10, 11) connected over a stiff elastic wire- or cable arrangement (14) and formed as a metallic, elongated blocking element. The wire- or cable arrangement comprises wire- or cable pieces (15, 16) that are helically formed. The end pieces are provided with multiple grooves (13) that are run transfers to a longitudinal direction on sides where the sides are averted to each other. The wire- or cable pieces alternatively run through the grooves of end pieces and are fixed in the grooves through deflected or pressed groove side areas. An independent claim is also included for a method for manufacturing a dampening- and spring arrangement.
