Nut Holding Element for Tight Brake Test Stand Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of motor vehicle brake testers is complicated by tight spatial conditions, leading to difficulties in securely positioning nuts during the assembly of bearing blocks, as they often fall or twist due to inaccessible installation spaces.
Innovation Solution
A holding element with recesses in the sheet metal that prevent nut twisting and a retaining bracket with gripping sections to securely hold the nuts in place, allowing for alignment and screwing without manual holding, using anti-slip materials or magnetic features if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screw connection assembly is used in tight spaces, then the bearing block can be mounted on the carrier, but the nuts fall off or twist during assembly due to inaccessible installation space
Solution Approach 1:
A sheet metal component with recesses serves as an intermediary between the nut and the assembly process. The recesses capture and hold the nuts, preventing them from falling off or twisting during assembly. This intermediary structure enables reliable nut positioning in previously inaccessible tight spaces.
Solution Approach 2:
The nuts are preliminarily positioned and secured in the recesses of the sheet metal before the actual screwing operation begins. This preliminary action ensures that the nuts remain in the correct position throughout the assembly process, eliminating the need for continuous manual holding.
2Manufacturing precision
If manual holding of nuts is required during assembly, then nuts can be positioned accurately, but assembly time increases and productivity decreases
Solution Approach 1:
The sheet metal with recesses performs the positioning function automatically without requiring operator intervention. The recesses self-capture the nuts and maintain their position throughout assembly, enabling the system to serve itself rather than relying on manual holding, thus improving productivity while maintaining precision.
3Ease of operation
If the installation space is tight and inaccessible, then the bearing block mounting becomes difficult, but adding holding structures increases device complexity
Solution Approach 1:
The sheet metal component serves multiple functions simultaneously: it acts as a structural element of the bearing block assembly, provides a mounting surface for the holding bracket, and creates recesses for nut positioning. This multi-functionality enables the structure to address accessibility issues without proportionally increasing complexity.
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
Facilitates easier assembly by preventing nut twisting and ensuring secure positioning even in hard-to-reach areas, allowing for proper alignment and screwing of the bearing block to the carrier, thus simplifying the installation process.
Implementation Method 1
an elastic holding bracket having at least one first gripping section which, in the assembled state of the holding element, is designed to grip the sheet metal and the support at a first point and to clamp them against one another
Implementation Method 2
The recesses are designed such that they prevent rotation of a square, in particular hexagonal, nut inserted into the recess. The nuts' rotation in the recesses is prevented, for example, by the nuts having a non-circular radial outer cross-section and being positively prevented from rotating in the recesses by abutting against parts of the recess during rotation
Implementation Method 3
Suitable anti-slip materials or adhesives can also be provided on the recess to hold the nut in the recess
Implementation Method 4
The recess can also be made magnetic, for example by inserting magnets, and thus hold the nuts, especially if the sheet is not made of steel but of plastic or aluminum

AI summary
Holding element 6 for positioning nuts 20 on a support 22, comprising a sheet metal plate 24 having at least two recesses 26 for at least partially receiving the nuts 20, wherein the recesses 26 are designed in such a way as to prevent a square, in particular hexagonal, nut 20 inserted into the recess from rotating, wherein the recesses 26 each have an insertion side 36 and are further designed in such a way that the nuts 20 can be inserted into the recesses 26 from the insertion side 36 and are prevented from passing completely through the recesses 26; and comprising an elastic retaining bracket 30, which has at least a first gripping section 32, which is arranged to grip the sheet metal plate 24 and the support 22 at a first point in the assembled state of the holding element 6 and to clamp them against each other.
