Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exhaust duct covers for utility vehicles are cumbersome to attach and prone to loosening due to vibrations, compromising their effectiveness in reducing heat transfer to adjacent components.
Innovation Solution
A modular exhaust duct cover system with integrated segments and fastening bands that securely attach to the exhaust duct and muffler, utilizing supports and fastening bands to ensure easy installation and resistance to vibration-induced loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional exhaust duct covers with separate cover segments are used, then the exhaust duct can be covered, but the attachment becomes troublesome and bolts may loosen due to vibrations
Solution Approach 1:
The exhaust duct cover is divided into two cover segments that can be attached separately to the exhaust duct. Each cover segment has fastening holes that align with attachment holes in the exhaust duct, allowing for simplified installation without requiring complex fastening mechanisms. The segmentation allows the cover to be easily assembled and disassembled while maintaining secure attachment.
Solution Approach 2:
The invention replaces the conventional bolt-based fastening system with a tab-and-slot mechanical interlocking system. The tabs on the cover segments engage with slots in the exhaust duct, creating a vibration-resistant connection that eliminates the need for bolts. This mechanical substitution provides both ease of attachment and reliable resistance to loosening under vibrational conditions.
2Adaptability or versatility
If multiple separate cover segments are used for upstream exhaust duct sections, then individual sections can be covered, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The invention merges the attachment operations for multiple exhaust duct sections by providing cover segments that can be attached simultaneously or in quick succession. The standardized fastening holes and tabs allow each cover segment to be rapidly secured without requiring separate complex fastening procedures, significantly reducing the total attachment time while maintaining comprehensive coverage of all exhaust duct sections.
