Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating devices for machine elements like exhaust gas pipes and manifolds in internal combustion engines are inefficient in meeting stricter insulation requirements, require significant engineering work for installation and dismantling, and do not adequately address the risk of fire from escaping fuel vapors, particularly in marine applications where temperature must be kept below 220°C to ensure safety.
Innovation Solution
A modular insulating device comprising a base plate, side parts, and a hood with a double wall configuration, allowing for easy assembly and disassembly without modifying existing systems, using a simple and sturdy design that includes a hood and insertion parts with clamping connections to ensure tight seals and prevent heat dissipation, and features heat-resistant gaskets to manage fuel vapor risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a prior-art insulating device with fasteners and screwed connections is used, then the insulating device can be attached to the exhaust gas pipe, but assembly and dismantling require substantial engineering work and time
Solution Approach 1:
The insulating device is divided into modular segments (first insulating segment for the exhaust gas pipe and second insulating segment for the exhaust gas manifold) that can be independently assembled and dismantled. This segmentation eliminates the need for complex fasteners and screwed connections, allowing rapid assembly and maintenance without substantial engineering work.
2Adaptability or versatility
If the insulating device is designed to cover additional machine elements like exhaust gas manifolds, then insulation coverage is improved, but device complexity increases
Solution Approach 1:
The insulating device is divided into modular segments (first insulating segment for the exhaust gas pipe and second insulating segment for the exhaust gas manifold) that can be independently assembled and dismantled. This segmentation allows the device to cover multiple machine elements while keeping each segment simple in structure, avoiding overall complexity increase.
Solution Approach 2:
The insulating device is designed as a universal solution that can insulate different machine elements (exhaust gas pipe and exhaust gas manifold) using standardized modular segments. This multi-functionality approach allows the same basic segment design to serve multiple purposes across different applications.
3Adaptability or versatility
If the insulating device uses a modular design with detachable insertion parts, then adaptability to different engine configurations is improved, but manufacturing complexity increases
Solution Approach 1:
The insulating device is divided into modular segments (first insulating segment for the exhaust gas pipe and second insulating segment for the exhaust gas manifold) that can be independently assembled and dismantled. This segmentation allows the device to cover multiple machine elements while keeping each segment simple in structure, avoiding overall complexity increase.
4Reliability
If the hood and insertion parts use double wall configuration with insulating material, then insulation efficiency is improved, but material consumption increases
Solution Approach 1:
The double wall configuration with insulating material is applied locally at critical areas (hood and insertion parts) where heat loss needs to be minimized, rather than throughout the entire insulating device. This localized approach improves insulation efficiency while minimizing additional material consumption.

AI summary
The invention relates to an insulating device containing a first machine element, in particular an exhaust gas pipe, and at least one second machine element, in particular an exhaust manifold. The insulating device at least partially surrounds the machine element and is connected to the unit. A base plate connected to the unit is provided-having at least two side parts arranged at a distance from each other forming an intermediate area, such that a sliding part is arranged in the intermediate area and is essentially sealingly connected the base plate and to the lateral parts by profiles and is detachably connected in relation to the base plate, a cover can be connected to the base plate by a detachable securing element. The cover rests upon the lower edges on associated areas of the lateral parts of the base plate and/or the sliding part(s).
