Asymmetric Grid Holding Element for Direct Tolerance Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grid-holding elements are limited in their ability to be mounted directly using a hand-held setting tool and require auxiliary means to secure a grid to a support or constructional component.
Innovation Solution
A grid-holding element with a saddle-shaped attachment section and angled surface sections that act as a springy hinge, providing a tolerance range for secure mounting without auxiliary elements, allowing for adjustable height and preventing the hook-shaped end from slipping off during securing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional grid-holding element with symmetric foot sections is used, then the structure is simple and easy to manufacture, but it cannot provide adequate height tolerance and requires auxiliary mounting means
Solution Approach 1:
The attachment section features asymmetric foot sections where the first foot section has a maximal extension length greater than the second foot section in the perpendicular direction. This asymmetry creates a tolerance range that accommodates height variations in the support structure, enabling direct mounting without auxiliary means while maintaining structural simplicity
Solution Approach 2:
The invention introduces a height dimension difference between the two foot sections of the attachment section. By varying the extension length in the perpendicular direction, the patent creates a three-dimensional tolerance zone that allows the holding element to adapt to height variations in the support, eliminating the need for auxiliary mounting components
2Adaptability or versatility
If the holding element height is fixed with precise tolerance, then mounting precision is improved, but the element cannot adapt to height variations in support structures
Solution Approach 1:
The asymmetric design of the foot sections with different maximal extension lengths creates an inherent tolerance range. The first foot section extends further than the second foot section in the perpendicular direction, providing a built-in adjustment range that adapts to support height variations without requiring high manufacturing precision
Solution Approach 2:
The patent changes the geometric parameters of the attachment section by making the foot sections asymmetric. Specifically, the maximal extension length of the first foot section is designed to be greater than that of the second foot section, creating a parameter-based tolerance mechanism that provides adaptability while relaxing manufacturing precision requirements
3Reliability
If auxiliary mounting means are used to secure the grid, then mounting reliability is improved, but the device complexity and number of components increases
Solution Approach 1:
The invention merges the mounting function directly into the holding element itself through the asymmetric attachment section. The foot sections with different extension lengths integrate the tolerance compensation and mounting functions into a single component, eliminating the need for separate auxiliary mounting means while maintaining reliable attachment
Solution Approach 2:
The attachment section is designed to perform multiple functions: it provides structural support, accommodates height variations through asymmetric foot sections, and enables direct mounting with setting tools. This multi-functionality eliminates the need for additional auxiliary components, reducing overall device complexity while maintaining mounting reliability

Function Achieved in This Case
Enables easy and secure mounting of the grid-holding element using a setting tool, eliminating the need for auxiliary means and ensuring stability across a tolerance range, enhancing the holding element's height adjustment capabilities.
Implementation Method 1
The first leg has a first surface section and at least one second surface section forming an angle with the first surface section, a bending axis between the two surface sections extends transverse to a longitudinal extent of the first leg. The angle between the surface sections can be acute or obtuse. As a result, both surface section act as a springy hinge, with surface sections pulling away form each other under a heavy load.
