Solution Overview
Problem
Existing insulating coverings for machine or engine parts require complex disassembly and significant maintenance time for replacement, leading to increased costs and inefficiencies in thermal insulation.
Innovation Solution
A reversible and non-destructive attachment method using a single metallic jacket body with snap fasteners or magnetic forces, allowing for easy installation and removal of insulation without the need for expanding rivets, enabling efficient recycling and adaptation to varying temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer sheath body and inner sheath body are joined together by flanging, bending tabs, or riveting and welding to form a receiving space for the insulation, then the insulation is securely housed between the sheath bodies, but the insulation becomes difficult to remove and requires complex disassembly for replacement
Solution Approach 1:
The insulating cladding is divided into separate components: an outer sheath body and an inner sheath body that can be independently assembled and disassembled. The insulation layer is sandwiched between these segmented parts, allowing the sheath bodies to be separated for insulation replacement without damaging the insulation itself.
Solution Approach 2:
The connection between the outer and inner sheath bodies is made reversible through snap-fastener elements that allow dynamic assembly and disassembly. This replaces permanent joining methods with a system that can be repeatedly connected and disconnected, enabling easy maintenance while maintaining secure housing during operation.
2Reliability
If the insulation is housed between the outer sheath body and inner sheath body and often not easily removable, then the insulation is protected in place, but replacement requires complex disassembly and significant maintenance time
Solution Approach 1:
The snap-fastener elements are pre-integrated into the sheath body structure during manufacturing. This preliminary integration of fastening mechanisms eliminates the need for complex assembly operations during maintenance, allowing quick release and replacement of the insulation layer without requiring disassembly of complex joint structures.
Solution Approach 2:
The inner sheath body with the insulation layer can be extracted as a complete assembly from the outer sheath body. The snap-fastener connection allows the inner assembly to be removed as a unit, enabling quick replacement of insulation without disturbing the outer sheath structure or requiring separation of multiple joined components.
3Reliability
If expanding rivets are used to attach insulation to the sheath body, then the insulation is securely fixed, but manufacturing costs increase and the process becomes more complex
Solution Approach 1:
The fastening function is merged into the sheath body structure itself through integrated snap-fastener elements. Instead of using separate expanding rivets that require additional manufacturing steps and materials, the fastening mechanism is combined with the sheath body, simplifying the manufacturing process while maintaining secure fixation of the insulation layer.
4Weight of moving object
If a single metallic jacket body is used without an inner sheath body, then metal and weight are reduced, but the insulation cannot be easily removed and replaced
Solution Approach 1:
The single jacket body is segmented into an outer sheath body and an inner sheath body that can be separated. This segmentation allows the insulation layer to be accessed and replaced by removing the inner sheath body, while the outer sheath body remains in place. The segmentation enables maintenance functionality without requiring a completely different single-piece design.

Implementation Method 1
The insulation (5) is detachably fastened in a reversible and non-destructive manner to the casing body (2) by a snap fastener connection
Implementation Method 2
insulation could be reversibly attached to a metallic sheath body using snap fasteners, magnetic forces or similar
Implementation Method 3
The insulation ensures that the temperature of the outer jacket body is significantly lower than the temperature of the inner jacket body, which faces a machine or motor part
