Solution Overview

Problem

Existing tool holder systems for perforated grids lack a secure and easy-to-use mechanism for attaching and detaching tools, particularly in workshops, where tools need to be easily accessible and organized.

Innovation Solution

A tool holder base insert with a hook device and a safety device that can be elastically deflected to allow easy installation and removal, featuring a hook shank and hook head for form-fitting contact with the grid plate and a U-shaped securing section that pivots relative to the base body section, providing secure attachment and easy detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hook device is inserted into a receiving hole of a perforated grid plate to attach a tool holder base insert, then the tool holder can be securely attached to the grid plate, but the tool holder cannot be easily detached without additional mechanisms

Engineering Contradiction:
Improveattachment securityVSAvoiddetachment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hook device incorporates a safety device with a head that can pivot between a first position (blocking removal) and a second position (allowing removal). This dynamic mechanism allows the same component to provide both secure attachment during normal use and easy detachment when needed, resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a safety device is added to prevent removal of the tool holder base insert from the perforated grid plate, then the attachment security is improved, but the device complexity increases

Engineering Contradiction:
Improveattachment securityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The safety device is integrated into the hook device as a unified component. The head of the safety device forms part of the overall hook assembly, and the pivot mechanism is incorporated within the same structural envelope. This merging reduces the number of separate components and simplifies the overall device complexity while maintaining the security function.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the hook device has a form-fitting contact with the grid plate edge area, then the attachment reliability is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveform-fitting attachmentVSAvoidcontact surface precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The form-fitting contact is localized to specific areas: the shank of the hook device contacts the edge area of the grid plate at defined locations. By concentrating the form-fitting requirements to localized contact points rather than extensive surfaces, the manufacturing precision requirements are reduced while maintaining reliable attachment.

Inventive Principle:
Principle #3Local quality

AI summary

The invention is based on the object of proposing a tool holder base insert for a perforated panel, which forms an alternative to the known holders. This object is achieved by a tool holder base insert 3 for a perforated panel 2; 2a, b, c having a bearing surface 11 for bearing the tool holder base insert 3 on the perforated panel 2; 2c in an installed state of the tool holder base insert 3, having at least one hook device 8, wherein the hook device 8 projects beyond the bearing surface 11 in a plug-in direction E, and therefore the hook device 8, in the installed state of the tool holder base insert 3, can engage through one of the accommodating holes 4, wherein, in the installed state of the tool holder base insert 3, a peripheral panel region is arranged in a panel-accommodating region 9, and having at least one securing device 14, wherein the securing device 14, in the installed state of the tool holder base insert 3, is arranged in one of the accommodating holes 4 and secures the tool holder base insert 3 in a form-fitting manner against being displaced counter to the loading direction B, wherein the tool holder base insert 3 has a main-body portion 5 and a securing portion 6, wherein the main-body portion 5 defines the bearing surface 11 and carries the hook device 8, and wherein the securing portion 6 carries the securing device 14, wherein the main-body portion 5 and the securing portion 6 are arranged for movement in relation to one another, and therefore the securing device 14 can be deflected elastically, counter to the plug-in direction E, relative to the hook device 8.
