Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fume exhaust devices have low fume exhaust efficiency, resulting in high resistance and noise, which negatively impacts user experience due to increased air volume and speed.
Innovation Solution
A fume exhaust device with a cooking fume separation system featuring adjustable separation passages, where the relative position of brackets is automatically adjusted based on fan air volume, reducing resistance and improving extraction efficiency while minimizing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the speed level of the fume exhaust device is increased to improve fume extraction efficiency, then the air volume increases, but the resistance becomes significantly greater and noise increases
Solution Approach 1:
The patent applies the dynamics principle by making the separation passages adjustable in size. The brackets holding the separation plates can be moved relative to each other, allowing the separation passages to expand or contract dynamically. This enables the system to adapt to different air volumes and speed levels, reducing resistance when high speed is used while maintaining effective separation at lower speeds.
Solution Approach 2:
The patent changes the physical parameter of the separation passage size to optimize performance. By adjusting the distance between brackets and the configuration of separation plates, the passage cross-sectional area is varied. This parameter change allows the system to handle different air volumes efficiently, reducing resistance at high air volumes while maintaining separation effectiveness.
2Productivity
If the speed level of the fume exhaust device is increased to improve fume extraction efficiency, then the air volume increases, but the noise increases
Solution Approach 1:
The adjustable separation passages allow the system to dynamically adapt to different operating conditions. At high speed levels, the passages can be opened wider to reduce turbulence and noise, while still maintaining effective fume separation. This dynamic adjustment mitigates the noise increase that would normally accompany higher speed operation.
3Reliability
If the separation passage size is reduced to improve fume separation effectiveness, then the resistance increases, but the air flow is restricted
Solution Approach 1:
The patent employs adjustable brackets that allow the separation passage size to be modified based on operating requirements. When high separation effectiveness is needed, the passages can be narrowed, and when high air flow is the priority, the passages can be widened. This dynamic adjustability resolves the contradiction between separation effectiveness and air flow productivity.
Solution Approach 2:
By changing the geometric parameters of the separation passages through adjustable brackets, the system can optimize the balance between separation effectiveness and air flow. The passage dimensions are not fixed but can be modified to match the specific operating conditions, allowing both high separation performance and adequate air flow to be achieved.
