Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air-cooled refrigerators suffer from inefficient air circulation and temperature fluctuations due to lack of control over air flow paths, leading to uneven refrigeration and preservation performance across storage compartments.
Innovation Solution
A device with multiple air flow paths featuring a housing with adjustable air outlets, a rotation disk member, and a gear transmission mechanism that allows precise control of air flow distribution and reduces motor jittering, enabling uniform air regulation and reduced thickness for enhanced storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex air passage system with multiple control devices is used to regulate air flow to each storage compartment, then the air distribution control capability is improved, but the device complexity increases and unified control becomes inconvenient
Solution Approach 1:
The patent combines multiple air outlet adjustment functions into a single integrated air passage assembly. One adjustment member controls multiple air outlets simultaneously, allowing unified regulation of air flow distribution to different storage compartments without requiring separate control devices for each outlet, thus simplifying the overall system structure while maintaining adaptability
Solution Approach 2:
The adjustment member is designed to perform multiple functions: it can simultaneously regulate air flow to different storage compartments, control air distribution ratios, and adapt to varying refrigeration demands. This multi-functional design eliminates the need for multiple specialized control devices, reducing system complexity while preserving comprehensive control capability
2Length of stationary object
If the motor is positioned close to the rotation disk member to reduce device thickness, then the space requirement is reduced, but the motor jittering may affect the stability of air flow control
Solution Approach 1:
The patent introduces a transmission mechanism as an intermediary between the motor and the rotation disk member. This transmission mechanism acts as a buffer that isolates the motor's jittering from the air outlet adjustment system, ensuring stable air flow control even when the motor is positioned close to the rotation disk member, thus maintaining both compact dimensions and control reliability
