Rotating Pump Mount for Compressor Oil Return Under Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation enclosures for temperature-sensitive items face challenges in maintaining desired temperatures due to extreme ambient conditions, and existing cooling systems may not adequately address these issues, particularly when subjected to shock and vibration during transport.
Innovation Solution
A transportation enclosure equipped with a rotating pump mount and shock-absorbing supports, featuring a heating/cooling system that includes a coil surrounding the product carrier, a refrigeration system with a compressor, and lightweight yet high-strength supports to absorb shock and promote airflow, ensuring efficient operation and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a refrigeration system with compressor is used for active cooling, then temperature control capability is improved, but oil return and starvation issues occur under extreme ambient conditions and shock/vibration
Solution Approach 1:
The pump mount is designed to rotate dynamically in response to shock and vibration events. The rotating mechanism allows the pump to self-adjust its orientation and position during transportation, enabling the refrigeration system to maintain reliable operation and proper oil return under varying ambient conditions and shock/vibration exposure.
2Object-affected harmful factors
If shock-absorbing supports are added to protect against shock and vibration, then protection capability is improved, but device complexity increases
Solution Approach 1:
The shock-absorbing support structure is merged with the pump mount assembly. The support structure serves dual functions: protecting the pump from shock and vibration damage while also providing the rotational mechanism for the pump mount. This integration reduces overall device complexity by combining multiple functions into a single unified structure.
Solution Approach 2:
The support structure is designed to perform multiple functions simultaneously: it acts as both a shock-absorbing element and a rotational mount for the pump. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining protection capabilities.
3Weight of moving object
If lightweight supports are used to reduce overall weight, then weight is reduced, but shock absorption capability may be compromised
Solution Approach 1:
The support structure utilizes composite materials that provide high strength-to-weight ratio. These composite materials enable the lightweight support to maintain adequate shock absorption capability while significantly reducing the overall weight of the transportation device. The rotating mechanism also contributes by allowing the pump to self-position, reducing the need for overly robust (and heavy) fixed mounting structures.
