Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting techniques for refrigeration units on composite cargo vehicles compromise the structural integrity of the vehicle and require expensive, time-intensive manufacturing processes.
Innovation Solution
An embedded mounting assembly with a mounting insert embedded within the composite material of the vehicle's wall, utilizing a two-piece mounting bolt system that maintains structural integrity and supports the refrigeration unit without penetrating the outer surface, combined with a cover plate for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional mounting techniques are used to attach refrigeration units to composite cargo vehicles, then the refrigeration unit can be mounted, but the structural integrity of the composite material is compromised and manufacturing becomes expensive and time-intensive
Solution Approach 1:
The mounting insert is pre-embedded within the composite panel during the panel manufacturing process, before the panel is assembled into the cargo vehicle. This preliminary action allows the insert to be integrated into the composite structure without requiring post-manufacturing modifications that would compromise structural integrity or increase manufacturing complexity
Solution Approach 2:
The mounting insert acts as an intermediary component between the composite panel and the refrigeration unit. It provides a secure mounting interface while being fully integrated within the composite structure, eliminating the need for external mounting hardware that would compromise the panel's structural integrity
2Strength
If mounting inserts are embedded within composite panels, then structural integrity is preserved, but the installation process becomes more complex
Solution Approach 1:
The mounting insert is designed as a universal component that can be integrated into standard composite panel manufacturing processes. It serves multiple functions: providing structural reinforcement, creating mounting holes, and enabling refrigeration unit attachment, thereby simplifying the overall installation process despite its integrated design
3Ease of operation
If the mounting insert extends through the outer surface of the composite material, then mounting is simplified, but thermal leakage and fluid intrusion risks increase
Solution Approach 1:
The mounting insert is fully nested within the composite panel, with its outer surface flush with or recessed into the panel's outer surface. This nesting arrangement eliminates protruding elements that would create thermal bridges or fluid intrusion pathways, while the insert's internal structure provides sufficient mounting capability
4Productivity
If conventional mounting methods are used, then installation is faster, but corrosion and water intrusion occur
Solution Approach 1:
The mounting insert is constructed from corrosion-resistant materials and fully integrated within the composite panel structure, eliminating direct exposure to moisture and corrosive environments. This composite integration maintains installation efficiency while providing superior protection against corrosion and water intrusion compared to conventional metal mounting methods
