Wire-Based Clamping Device for Rapid Tool Holder Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for tools and aids at the workplace are complicated and require reassembly for attachment to a mounting wall, resulting in high costs and long assembly times.
Innovation Solution
A holding device with a fastening element and holding part made from wire, where the wire ends are positively introduced into a fastening element supported by a profile bar with an undercut groove, allowing secure attachment using a single screw and preventing rotation, thus simplifying assembly and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing holding devices use complex structures with multiple parts, then secure attachment to mounting wall is achieved, but assembly time and working time increase significantly
Solution Approach 1:
The holding device is divided into three main segments: the profile bar (fastening device), the fastening element, and the holding part. This segmentation allows each component to be optimized independently while enabling rapid assembly through simple connection mechanisms, resolving the contradiction between secure attachment and assembly time.
Solution Approach 2:
The fastening element is pre-formed with a projection that fits into the undercut groove of the profile bar, and the holding part is pre-shaped from wire with ends designed to engage the fastening element. This preliminary preparation of connection features eliminates the need for complex assembly operations during installation, achieving both security and speed.
2Reliability
If existing holding devices use multiple screws or complex fastening mechanisms, then secure attachment is achieved, but production costs increase
Solution Approach 1:
The fastening element combines multiple functions into a single component: it serves as both the mounting interface and the connection element between the profile bar and holding part. This merging eliminates the need for separate fasteners, reducing part count and production costs while maintaining secure attachment through the integrated projection-groove-screw mechanism.
Solution Approach 2:
The profile bar with undercut groove serves multiple purposes: it provides structural support, enables rotational prevention through the groove geometry, and facilitates easy attachment/detachment. This multi-functionality reduces the need for additional specialized components, lowering production costs while ensuring secure attachment.
3Adaptability or versatility
If existing holding devices require reassembly for attachment, then adaptability is achieved, but assembly complexity increases
Solution Approach 1:
The holding device incorporates dynamic reversibility through the screw connection that allows easy attachment and detachment without complex reassembly procedures. The projection-groove mechanism provides stable engagement during use while allowing quick release when needed, achieving adaptability with minimal complexity.
Solution Approach 2:
The fastening element is designed as a separate, removable component that can be easily detached from both the profile bar and holding part. This extraction capability provides attachment flexibility without requiring complex reassembly of integrated parts, simplifying the overall assembly process while maintaining versatility.

AI summary
The device (10) has a fastener (14) attachable at a fastening device (12) and a holding member (16) for receiving tools and aids. The holding member is formed from a wire i.e. computer numerical controlled (CNC) stainless steel wire. One end of the wire is introduced in the fastener and supported in an assembly state by the fastening device. The fastening device comprises an undercut groove (18) with a section bar (20) matching a rotation-preventing protrusion. A hole (24) in the fastener is engaged by a cross-bolt (26) into a slot nut (28). The holding member for receiving a cable, a cup, a lobe, a small strap, a large strap, a pen holder, a tool holder quiver of a towel, or a bottle.
