Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigeration systems suffer from noise and vibration issues due to the use of springy metal strips for securing sub-units, inefficiency with single motor centrifugal fans, and inability to adapt to untraditional dimensions and locations, leading to heavy and difficult-to-install cooling systems.
Innovation Solution
A compact refrigeration unit featuring a twin cross flow blower system with a unique air blade configuration and moveable air flow diverter, along with a center cross flow motor and compact coil system, allowing for efficient air flow redirection and adaptation to various applications, and a new fan and motor unit with artful fastening clips for easy installation in top or side discharge configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If springy metal strips are used to secure the sub-unit to the housing, then the sub-unit can be easily installed and removed, but noise and vibration increase due to insecure fitting
Solution Approach 1:
The securing mechanism is divided into multiple discrete clips distributed around the sub-unit perimeter, each independently engaging with corresponding receptacles in the housing. This segmentation allows for secure fitting without requiring continuous metal strip contact, reducing vibration while maintaining ease of installation.
Solution Approach 2:
The traditional mechanical springy metal strip securing system is replaced with a clip-and-receptacle engagement system. The clips feature latching mechanisms that positively engage with receptacles, providing secure mechanical attachment without the continuous contact and potential resonance issues of metal strips.
2Device complexity
If a single traditional centrifugal fan is used with one motor, then the system structure is simple, but the cooling efficiency is insufficient and additional motor cooling fans are required
Solution Approach 1:
The motor cooling function and the main cooling fan function are merged into a single integrated fan unit. The fan is positioned to simultaneously draw air across the motor for cooling and push cooled air through the housing, eliminating the need for separate motor cooling fans while maintaining system reliability.
Solution Approach 2:
The single fan is designed to perform multiple functions: cooling the motor, circulating air through the housing, and providing the primary cooling airflow. This multi-functional design simplifies the system structure while ensuring adequate cooling efficiency for all components.
3Stability of the object's composition
If the refrigeration system is designed with fixed coil configuration, then the system structure is stable, but it cannot adapt to untraditional dimensions and access problems
Solution Approach 1:
The coil assembly is designed with flexible mounting brackets and adjustable positioning mechanisms that allow the coils to be repositioned within the housing. This dynamic configuration enables adaptation to different spatial requirements and access conditions while maintaining the structural integrity and functional stability of the refrigeration system.
Solution Approach 2:
The coil configuration allows for adjustment in multiple dimensions including horizontal position, vertical position, and angular orientation. This multi-dimensional adjustability enables the system to adapt to untraditional installations and various access conditions while preserving the core structural stability of the refrigeration unit.
4Reliability
If a heavy cooling system configuration is used to ensure stability and secure fitting, then the system is vibration resistant, but installation becomes difficult in overhead locations
Solution Approach 1:
The clip-and-receptacle securing system is designed to distribute mechanical loads evenly across multiple engagement points, counteracting the effects of gravity and vibration without requiring excessive weight in the system components. The latching mechanism provides positive mechanical engagement that resists vibration forces while keeping the overall system lightweight for easy overhead installation.
