Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blowers require inconvenient adjustments in air flow direction, as they are designed with a fixed orientation, limiting user flexibility during operation.
Innovation Solution
A blower with a regulating mechanism comprising a coupling member, a regulating knob, and a resetting member allows the blower body to rotate relative to the base, enabling easy adjustment of air flow direction without moving the base, utilizing a spring for stable resetting and a compact split-type coupling member design for smooth rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blower body is fixed on the base, then the structure is simple and stable, but the air flow direction cannot be adjusted conveniently
Solution Approach 1:
The coupling member is designed to be rotatable relative to the base, transforming the fixed mounting into a dynamic adjustable connection. This allows the blower body to rotate and adjust air flow direction while maintaining structural stability through the resetting member that returns the coupling member to its initial position after adjustment.
2Adaptability or versatility
If a regulating mechanism is added to allow rotation, then the air flow direction can be adjusted, but the structure becomes more complex
Solution Approach 1:
The mounting structure is segmented into distinct functional components: the coupling member for rotation, the resetting member for returning to initial position, and the limiting mechanism for controlling rotation range. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving the desired adjustability.
Solution Approach 2:
The resetting member automatically returns the coupling member to its initial position after adjustment without requiring external intervention. The limiting mechanism self-activates to prevent over-rotation, and the entire regulating mechanism operates autonomously once the user initiates the adjustment by rotating the coupling member.
3Adaptability or versatility
If the coupling member can rotate freely, then the air flow direction is highly adjustable, but the blower body becomes unstable
Solution Approach 1:
The coupling member transitions between a locked stable state and a rotatable adjustable state. The resetting member ensures it returns to the stable initial position after adjustment, and the limiting mechanism defines the boundaries of rotation, maintaining stability while enabling necessary adjustability.
Solution Approach 2:
The resetting member provides positional feedback by automatically returning the coupling member to its initial position. The limiting mechanism provides tactile feedback when the rotation reaches the predetermined limits, preventing over-rotation and ensuring the blower body remains stable within the designed range of motion.
