Cylindrical Component Mounting Assembly for Vibration and Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for cylindrical components in mobile air conditioning systems, such as accumulators, are complex and costly due to high thermal and pressure loads, particularly with CO2 as a refrigerant, requiring a more cost-effective and reliable solution.
Innovation Solution
A fork-shaped receptacle with orthogonal grooves and a blind hole on the cylindrical component, combined with a U-shaped holding device and fastening element, provides a secure and cost-effective fastening system. The holding device can be made of metal or plastic, with optional vibration-damping decoupling elements to absorb different directional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening arrangements with brackets and fasteners are used, then operational reliability is ensured, but device complexity and production cost increase
Solution Approach 1:
The patent combines the holding function and fastening function into a single integrated U-shaped receptacle structure. The receptacle includes integrated fastening openings in its legs, eliminating the need for separate brackets and fasteners. This merging reduces device complexity while maintaining the reliable holding of cylindrical components under thermal and pressure loads.
Solution Approach 2:
The U-shaped receptacle serves multiple functions simultaneously: it provides mechanical holding for the cylindrical component, includes integrated fastening openings for secure attachment, and can accommodate vibration-damping decoupling elements. This multi-functionality reduces the number of separate components needed while ensuring reliable operation.
2Reliability
If conventional fastening arrangements are used, then operational reliability is ensured, but manufacturing cost increases
Solution Approach 1:
By merging the holding structure and fastening elements into a single U-shaped receptacle, the number of parts to be manufactured and assembled is reduced. This integration simplifies the manufacturing process and reduces production costs while maintaining the reliable holding required for CO2 refrigerant systems.
Solution Approach 2:
The receptacle is designed with self-contained fastening openings integrated into its structure, allowing it to perform both holding and fastening functions without requiring additional separate fastening components. This self-sufficiency reduces manufacturing complexity and cost.
3Object-affected harmful factors
If vibration-damping decoupling elements are added, then vibration transmission is reduced, but device complexity increases
Solution Approach 1:
The patent introduces vibration-damping decoupling elements as intermediary components between the cylindrical component and the U-shaped receptacle. These decoupling elements absorb vibrations and reduce harmful transmissions while being integrated into the existing receptacle structure through the fastening openings, minimizing additional complexity.
4Strength
If the holding device is made of metal, then strength and reliability are improved, but weight increases
Solution Approach 1:
The patent allows the U-shaped receptacle to be manufactured from composite materials or plastic injection molded parts with fiber reinforcement. This enables the holding device to achieve sufficient strength and reliability for CO2 refrigerant systems while reducing the weight compared to traditional metal constructions.
