Refrigerant Compressor Housing Mounting With Clamp-Lock Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of refrigerant compressor housings to support elements in cooling devices is time-consuming, costly, and often results in damage due to rusted screw connections, making dismantling difficult, and conventional clamping or latching methods are also inefficient.
Innovation Solution
A device using clamping or latching connecting elements that can be arranged on either the housing or the carrier element, allowing for a rotational movement to secure the housing in a stable and vibration-resistant manner, eliminating the need for screws and simplifying assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to fasten the housing to the carrier element, then the connection is secure and reliable, but the assembly is time-consuming and difficult to dismantle due to rusting
Solution Approach 1:
The patent replaces the traditional screw connection system with a clamping connection system. The connecting element features a clamping jaw that engages with the carrier element through a clamping action, eliminating the need for threaded fasteners. This substitution maintains connection reliability while dramatically reducing assembly time and eliminating rust-related dismantling difficulties.
Solution Approach 2:
The connecting element is divided into functional segments: a clamping jaw for engagement, a shank for insertion, and a foot for positioning. This segmentation allows the clamping action to be performed separately from the positioning action, enabling quick assembly without complex threading operations while maintaining secure connection.
2Reliability
If screw connections are used to fasten the housing to the carrier element, then the connection is secure, but the assembly requires special tools and many components increasing complexity and cost
Solution Approach 1:
The patent merges the functions of positioning and fastening into a single connecting element. The clamping jaw simultaneously provides positioning accuracy and secure fastening through one integrated component, eliminating the need for separate positioning fixtures and fasteners, thereby reducing assembly complexity and component count while maintaining connection reliability.
Solution Approach 2:
The connecting element serves multiple functions: it positions the housing relative to the carrier element, provides clamping force for secure attachment, and enables tool-free assembly. This multi-functionality reduces the number of specialized components needed while maintaining reliable connection.
3Ease of operation
If conventional clamping connections are used, then assembly is simpler, but production and dismantling are associated with high assembly costs
Solution Approach 1:
The clamping jaw is designed to be self-aligning and self-clamping. When the connecting element is inserted, the clamping jaw automatically engages with the carrier element through elastic deformation or mechanical leverage, eliminating the need for specialized assembly tools or complex adjustment procedures. This self-service mechanism simplifies operation while reducing manufacturing costs through fewer specialized components.
