Problem
Slim range hoods require diverse air passage assemblies to match different product sizes and appearances, leading to high development investments and low standardization, which hinders the expansion of product series and iterative upgrades.
Innovation Solution
A slim range hood design featuring a detachable air guide cover that matches the volute with different air guide covers, allowing for various product structure sizes and air outlets, enabling high standardization, reduced development investment, and a shorter development cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different air passage assemblies are designed for each product size and appearance, then product customization and user needs satisfaction are improved, but development investment increases and standardization decreases
Solution Approach 1:
The volute is designed as a universal core component that can be matched with different air guide covers to create air passage assemblies for various product sizes and appearances. This multi-functional design allows a single volute to serve multiple product configurations, reducing the need to develop separate air passage assemblies for each product variant.
Solution Approach 2:
The air passage assembly is segmented into modular components: a standardized volute and interchangeable air guide covers. This segmentation allows the core volute to remain unchanged while only the air guide cover needs to be changed to accommodate different product requirements, significantly reducing development complexity.
2Shape
If different air passage assemblies are designed for each product size and appearance, then product appearance diversity is improved, but manufacturing standardization deteriorates
Solution Approach 1:
The volute serves as a universal component that maintains consistent manufacturing standards across all product variants. By keeping the volute design standardized and only changing the air guide covers, manufacturing processes for the core component remain standardized while still achieving diverse product appearances.
Solution Approach 2:
The air passage assembly is divided into a standardized volute portion and interchangeable air guide cover portions. This segmentation allows the volute to be manufactured using standardized processes, while the air guide covers can be varied to achieve different product appearances without affecting the manufacturing standardization of the core component.
Applied Scientific Principles

AI summary
The present disclosure discloses a slim range hood, including: a box body having an internal circulation air outlet; and a fan assembly arranged in the box body and including a volute and an air guide cover. The volute includes an air inlet part and a first air outlet part connected to an air outlet of the air inlet part. The air guide cover is detachably mounted at an air outlet of the first air outlet part and is configured to guide an air flow sucked in by the fan assembly to the internal circulation air outlet. With the slim range hood, a design of matching the volute with different air guide covers is realized by mounting the detachable air guide cover at the first air outlet part, different product structure sizes and air outlets of different sizes are satisfied, and different types of products have the same core component. Therefore, high standardization is provided, the development investment is low, and the development cycle is short, which are conducive to expansion of product series and iterative upgrade of product performance.
