Insulation Holder Latching Mechanism for Slipping Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for insulating materials are complex, expensive, and unsuitable for thicker, heavier materials, leading to slipping and deformation, which compromises thermal insulation.
Innovation Solution
An insulating material holder with a shaft and multiple holding plates featuring a latching connection that allows easy forward movement but blocks rearward movement, ensuring secure attachment without additional tools and reducing packaging costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening devices are used for thick insulating material, then the insulating material can be attached to the substrate, but the heavy material slips off and deforms due to insufficient holding force
Solution Approach 1:
The fastening device is segmented into a shaft and multiple holding plates that can be separately assembled. The holding plates are distributed along the shaft to provide multiple contact points with the insulating material, distributing the holding force across several locations rather than relying on a single attachment point. This segmentation allows the device to securely hold heavy, thick insulating materials without slipping or deforming.
2Reliability
If complex fastening devices with multiple components are used, then secure attachment is achieved, but assembly becomes complex and production cost increases
Solution Approach 1:
The holding plates are integrated with the shaft through a simple latching connection rather than being separate complex components. The latching means allows the holding plates to be easily attached to and removed from the shaft, merging the function of multiple components into a unified, simple assembly system. This reduces both device complexity and assembly steps while maintaining secure attachment.
Solution Approach 2:
The latching connection is designed to be self-actuating during assembly. The holding plates automatically engage with the shaft through their latching means without requiring additional tools or complex alignment procedures. This self-service mechanism simplifies the assembly process and reduces production costs while ensuring reliable attachment security.
3Ease of operation
If conventional fastening devices are used, then insulating material can be attached, but additional tools are required during assembly and packaging volume is large
Solution Approach 1:
The latching connection between holding plates and shaft is designed to engage automatically during assembly without requiring additional tools. The holding plates simply snap onto the shaft through their latching means, making the assembly process tool-free and straightforward. This self-service mechanism significantly improves ease of operation while reducing the number of components that need to be packaged.
Solution Approach 2:
The holding plates can be nested along the shaft in a compact arrangement, allowing multiple holding plates to occupy minimal space when not in use. This nesting capability reduces the overall packaging volume required for transporting and storing the fastening device components, addressing the packaging volume concern while maintaining assembly simplicity.
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
The solution enables quick, easy, and cost-effective installation with optimal contact pressure, preventing slipping and deformation, and reducing the number of holders needed per area.
Implementation Method 1
the shank and each of the holding plates have latching means which form a latching connection. This latching connection means that the multiple retaining plates can be moved easily from a rear end area of the shaft, i.e. the area that faces away from the ground when assembled, in the direction of the front end area, but a movement of the multiple retaining plates back in the direction of the rear end portion of the shaft is blocked.

AI summary
The holder (1) has a shaft (5) comprising a connector (6) provided in a front end region (9) to directly or indirectly fasten the shaft in or at a substrate (4). A retainer plate (7) holds insulating material (2). The shaft and the retainer plate comprise a latch unit for formation of a detent connection. The latch unit is formed such that the retainer plate is moved from a rear end region (8) of the shaft in a direction of the front end region. The latch unit blocks movement of the retainer plate back in a direction of the rear end region of the shaft. An independent claim is also included for a method for fastening insulating material at a substrate.
