Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing airflow-direction adjustment devices for cooling and heating equipment are complex, heavy, and difficult to operate due to their intricate link mechanisms and large first connection elements, which hinder weight reduction and operational excellence.
Innovation Solution
The proposed airflow-direction adjustment device simplifies the structure by using a link mechanism that connects two or more fins through an intermediate fin, with a switch or operating knob, and two first links that turnably connect to the fins and switch, eliminating the need for additional links and latch mechanisms, thereby reducing weight and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex link mechanism with multiple links and latch mechanisms is used, then the airflow-direction adjustment device can achieve parallel and scattered air-blowing modes, but the device becomes heavy and structurally complicated
Solution Approach 1:
The device divides the fin assembly into multiple independent fins (first fins, intermediate fin, second fins) that can be controlled separately through the link mechanism, enabling different air-blowing modes through selective positioning of each fin segment
Solution Approach 2:
The link mechanism is designed to perform multiple functions: it controls the positioning of multiple fins simultaneously, enables both parallel and scattered air-blowing modes, and integrates the switch operation directly into the fin control system, eliminating the need for separate latch mechanisms
2Adaptability or versatility
If a complex link mechanism with multiple links and latch mechanisms is used, then the airflow-direction adjustment device can achieve parallel and scattered air-blowing modes, but the device weight increases
Solution Approach 1:
The switch is integrated directly with the link mechanism, combining the control operation and the fin positioning function into a single unified structure. This eliminates separate latch mechanisms and reduces the overall number of components, thereby reducing device weight while maintaining mode switching capability
3Reliability
If a large first connection element is used in the link mechanism, then the fins can be effectively controlled, but the device becomes difficult to operate and heavier
Solution Approach 1:
The link mechanism employs arc-shaped grooves that guide the pins through predetermined paths, dynamically adapting the connection geometry during operation. This allows the mechanism to maintain effective fin control through the geometric constraints of the arc grooves while keeping individual connection elements compact and easy to operate
