Solution Overview

Problem

Existing methods for mounting pivoting levers on C- or U-profile slide tracks face challenges due to limited space, making it difficult to insert screw bolts from the inside, which prevents stable attachment of bearing bolts perpendicular to the driving direction.

Innovation Solution

A holding element with angled first and second holding sections featuring projections that fit into openings on the track, allowing for secure attachment without screw fittings, and can be welded for stability, including a locking section for secure assembly and multiple projections for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external holders with screw fittings are used to attach bearing bolts to tracks, then the bearing bolts can be securely attached perpendicular to the driving direction, but the mounting process becomes complicated and requires more installation space

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

Solution Approach 1:

The holding element merges the support function and the attachment function into a single integrated component. The support section provides bearing surface for the pivoting lever while the holding sections with projections provide attachment to the track, eliminating the need for separate holders and screw fittings

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts the screw fitting requirement entirely from the mounting process. By using projections that fit into openings and can be welded, the solution removes the need for threaded holes and screw bolts, simplifying both the holding element design and the mounting procedure

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If screw bolts are inserted from the inside through openings in the track, then the mounting process is simplified, but the limited space in the track prevents this approach

Engineering Contradiction:
Improvemounting easeVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

Instead of inserting fastening elements from the inside of the track as conventionally done, the invention inverts the approach by having the holding element approach the track from the outside. The projections extend outward to engage with openings in the track, allowing mounting without requiring internal access or internal insertion of fasteners

Inventive Principle:
Principle #13The other way round (Inversion)

3Stability of the object's composition

If multiple holding projections are provided on the holding element, then the holding element cannot twist during assembly and welding, but the device complexity increases

Engineering Contradiction:
Improveassembly stabilityVSAvoidholding element complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The holding sections are positioned at specific locations and angles (particularly perpendicular to each other) to provide optimal stability. This strategic placement of holding sections with projections ensures the element cannot twist during assembly, while the localised complexity is justified by the global stability benefit

Inventive Principle:
Principle #3Local quality

AI summary

A holding element, for supporting pivoting levers or the like, includes a support section for receiving an object to be supported as well as a first holding section and a second holding section. The first holding section includes at least a first holding projection and the second holding section at least a second holding projection. The first and the second holding sections are designed to rest against respective first and second contact sections of a component that is to be connected with the holding element. The holding projections are designed for being received in openings provided at the contact sections.
