Universal machine core component with interchangeable function for heater and fan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine core components for electric fans and heaters are distinct, making it impossible to switch between fan and heater functions by adding or removing heating elements, leading to increased design and mold opening costs, which is not conducive to batch and modular processing production.
Innovation Solution
A universal machine core component with a vertical structure, featuring a core housing with an air inlet at the bottom and an air outlet at the top, a driving motor, and a wind wheel, along with a heating element mounting window, allowing for the installation of a heating element to convert the component into a heater or removing it to function as a fan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate machine core components are used for electric fans and heaters, then each device can be optimized for its specific function, but design costs and mold opening costs increase
Solution Approach 1:
The patent applies universality by designing a machine core component that can serve both as an electric fan core and a heater core through the selective installation of a heating element. The core housing, air duct, motor mounting structure, and control circuit board are designed to accommodate both fan-only and heater-with-fan configurations, eliminating the need for completely separate design sets for each device type.

The core housing, air duct, motor mounting structure, and control circuit board are designed to accommodate both fan-only and heater-with-fan configurations, eliminating the need for completely separate design sets for each device type.
Solution Approach 2:
The patent applies segmentation by separating the heating element as an independent, optional component that can be selectively installed or removed. The control circuit board is also designed with modular switching circuits that can be selectively activated or deactivated based on whether a heating element is present, allowing the same physical platform to support different functional configurations without requiring complete redesign.
4Ease of manufacture
If a universal machine core component is used for both fans and heaters, then manufacturing costs are reduced, but the device must accommodate additional functionality
Solution Approach 1:
The patent applies the extraction principle by isolating the heating element as a separate, removable component rather than integrating it permanently into the core structure. Similarly, the heating function is extracted as an optional software/control feature that can be enabled or disabled independently. This allows the base machine core to remain relatively simple while accommodating additional heating functionality only when needed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The universal machine core component enables cost-effective and simplified production by allowing function interchange between heaters and fans, reducing manufacturing costs and processing difficulties, and is suitable for batch processing and production.
Implementation Method 1
a driving motor mounted inside the core housing; and a wind wheel coaxially connected to the driving motor
Implementation Method 2
a heating element mounting window located at the air inlet arranged for mounting a heating element selectively

AI summary
A machine core component, which is a universal part component for heater and fan manufacture, includes a core housing with a vertical structure having an air inlet at a lower end portion, an air outlet at an upper end portion, and an air duct formed between the air inlet and the air outlet; a driving motor and a wind wheel supported and received inside the core housing; and a heating element mounting window located at the air inlet for quick and easy installation of a heating element so that the machine core component can be used for fan or heater manufacture.
