Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circulation fans have limited flexibility in adjusting and fixing the air-out angle, which affects use convenience and user experience, and often lack multi-functional features.
Innovation Solution
A circulation fan design featuring a blowing assembly with a connecting assembly, including brackets, gears with teeth, and a movable shield, along with a motor, temperature sensor, display, and voice control, allowing for adjustable angles and enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the blowing assembly is fixed rigidly to the base, then structural stability is improved, but the ability to adjust air-out angle is lost
Solution Approach 1:
The shield is designed to be movable relative to the base through a connecting assembly with brackets, allowing the air-out angle to be dynamically adjusted while maintaining structural stability when positioned. The gear mechanism enables controlled movement between fixed angular positions.
2Ease of operation
If a gear mechanism with teeth is added to enable angle adjustment, then adjustability is improved, but device complexity increases
Solution Approach 1:
The connecting assembly is segmented into discrete components: first bracket, second bracket, and gear with teeth. This modular approach allows for precise angular positioning while keeping each component relatively simple in design.
3Ease of operation
If the shield is made movable to enable angle adjustment, then ease of operation is improved, but structural stability deteriorates
Solution Approach 1:
The connecting assembly acts as an intermediary between the movable shield and the fixed base. It provides controlled movement capability while maintaining structural integrity through the bracket and gear mechanism design.
