Receiver Drier Bottle Bracket Design to Reduce Vibration Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching a receiver drier bottle to a heat exchanger in automotive air conditioning systems are either space-consuming or require significant modifications, leading to potential damage and increased costs.
Innovation Solution
A compact heat exchanging module with an attachment means that restricts axial movement of the bottle without altering the refrigerant fluid circuit, using a combination of mounting brackets, screws, and radial projections to secure the bottle to the heat exchanger, minimizing space usage and maintenance impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bottle is attached only at one end to the heat exchanger, then the installation is simple, but the bottle vibrates and causes damage to the junction
Solution Approach 1:
The attachment function is segmented into two independent attachment means: one at the first longitudinal end of the bottle connected to the heat exchanger, and another at the second longitudinal end connected to the frame. This segmentation stabilizes the bottle by distributing attachment points while maintaining installation simplicity through modular components.
2Reliability
If existing attachment solutions are implemented to prevent bottle vibration, then junction durability improves, but space consumption increases significantly
Solution Approach 1:
The frame serves multiple functions: it provides structural support for the heat exchanger, accommodates the attachment means at the second longitudinal end of the bottle, and integrates vibration prevention without requiring additional space-consuming components. The attachment means utilizes existing frame structure rather than adding separate vibration prevention mechanisms.
3Reliability
If the refrigerant fluid circuit is altered to accommodate attachment solutions, then bottle stability improves, but system complexity and cost increase
Solution Approach 1:
The vibration prevention function is extracted from the refrigerant fluid circuit and implemented through the frame structure with attachment means. The attachment means at the second longitudinal end connects the bottle to the frame independently of the refrigerant circuit, eliminating the need to modify any refrigerant fluid circuit components while still achieving bottle stability.
4Reliability
If attachment means restrict axial movement of the bottle, then vibration and mechanical stress are reduced, but the attachment structure becomes more complex
Solution Approach 1:
The attachment means combines multiple functions into a single integrated component: it connects the bottle to the frame, restricts axial movement of the bottle, and provides structural support. By merging these functions into one attachment means rather than using separate components for each function, the overall structure complexity is minimized while achieving vibration resistance.
