Insulated Clamp Assembly for Heat Loss and Fire Risk Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp assemblies for hoses or pipes suffer from uncontrolled heat loss, which reduces system efficiency and poses a fire risk due to the discharge of heat to the environment or adjacent components, and arranging heat protection on clamps is complex due to varying shapes.
Innovation Solution
A clamp assembly with a heat protection device featuring a housing and insulation layers that can be connected to the clamp in a positive-locking or materially engaging manner, providing bidirectional heat insulation and adaptable to different clamp sizes, either as an integral component or a retrofit solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heat shield is fitted to clamps after assembly, then heat protection is provided, but assembly complexity increases due to varying clamp shapes
Solution Approach 1:
The heat protection device is merged with the clamp assembly by integrating the housing to surround the clamp and the insulation layer to fill the housing, creating a combined structure that provides both clamping and heat protection functions in one assembly unit
Solution Approach 2:
The housing is designed with a universal structure that can accommodate different clamp shapes and sizes through its circumferential wall and radial walls configuration, allowing the same heat protection device to be applied across various clamp types without increasing assembly complexity
2Strength
If metal clamps are used, then clamping strength is provided, but heat loss to environment increases
Solution Approach 1:
The insulation layer is nested within the housing which surrounds the metal clamp, creating a nested structure where the metallic clamp provides structural strength while the nested insulation layer provides thermal protection, allowing both functions to coexist
Solution Approach 2:
The insulation layer acts as an intermediary between the metal clamp and the external environment, blocking heat transfer from the clamp to surrounding components while the clamp itself maintains its clamping function
3Object-affected harmful factors
If insulation layer is added to housing, then heat insulation effect is improved, but assembly complexity increases
Solution Approach 1:
The insulation layer is pre-positioned within the housing structure, and the housing is designed to be assembled around the clamp in a straightforward manner, with the insulation layer already in place to provide immediate thermal protection upon assembly
Solution Approach 2:
The housing is designed as a flexible or adaptable structure that can be assembled around different clamp configurations, with the insulation layer conforming to the housing shape, allowing easy assembly without complex fitting procedures

AI summary
A clamp assembly has a clamp with a clamp band and a clamping device for clamping the clamping band and has a heat protection device with a housing and at least one insulating layer. The housing has a respective wall at each axial end face, the wall being divided into sections and protruding radially inwards, and the at least one insulating layer can be positioned between the walls of the housing. The clamp can be surrounded at least in some regions by the housing and/or the at least one insulating layer of the heat protection device, and the heat protection device is designed to be connectable to the clamp.
