Exhaust Pipe Cover Insulation for Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exhaust pipe systems in vehicles lack sufficient thermal insulation between exhaust pipes, leading to heat loss and inefficient heat management, which can cause the fuel tank and surrounding components to overheat.
Innovation Solution
A vehicle design featuring a first cover member that bridges over and covers the periphery of multiple exhaust pipes, with a thermal insulation member filling the space between their centers and surrounding areas, preventing the formation of uninsulated spaces and suppressing vibration of the insulation member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If no thermal insulation member is provided in the area on and in the vicinity of the centerline between the two exhaust pipes, then the exhaust pipes can be easily manufactured and installed, but heat generated from the exhaust pipes escapes and sufficient insulation between the exhaust pipes cannot be achieved
Solution Approach 1:
The patent applies local quality by providing thermal insulation members at specific locations - particularly in the area on and in the vicinity of the centerline between the two exhaust pipes where heat escape occurs. The insulation members are strategically positioned to target the specific heat loss problem area rather than uniformly insulating all exhaust pipe surfaces, thus achieving effective heat insulation while maintaining manufacturing simplicity.
2Device complexity
If a space with no thermal insulation member is formed on and in the vicinity of the centerline between the two exhaust pipes, then the exhaust pipe structure remains simple, but heat escapes from this space and sufficient insulation between the exhaust pipes cannot be achieved
Solution Approach 1:
The patent segments the thermal insulation system into multiple independent insulation members positioned at different locations around the exhaust pipes. Rather than using a single continuous insulation structure that would increase complexity, the system divides insulation into discrete units including members in the centerline area and members along the exhaust pipe surfaces, achieving effective heat insulation through coordinated segmentation.
Solution Approach 2:
The thermal insulation members act as intermediary elements between the two exhaust pipes, particularly the insulation member positioned in the area on and in the vicinity of the centerline. This intermediary insulation member fills the gap between the pipes, preventing direct heat transfer and thermal interaction between the exhaust pipes while maintaining structural simplicity.
3Productivity
If thermal insulation members are not sufficiently filled in the space between exhaust pipes, then installation is easier and faster, but heat of the exhaust pipes cannot be sufficiently insulated
Solution Approach 1:
The patent applies preliminary action by pre-positioning thermal insulation members in critical heat loss areas, particularly in the area on and in the vicinity of the centerline between the exhaust pipes, before final assembly. The insulation members are strategically placed in advance at locations where heat escape is most likely to occur, ensuring reliable heat insulation is established before the exhaust pipe system becomes operational, thus maintaining both installation efficiency and insulation reliability.
