Solution Overview
Problem
Existing motorized fans lack flexibility in configuration and power supply options, limiting their usability in various environments and locations.
Innovation Solution
A detachable fan device with a head assembly and base assembly that allows for both standing and table-top configurations, featuring a self-aligning receiving portion for easy coupling, multiple power sources, and an articulation mechanism for leg extension, enabling hands-free alignment and continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fan device uses a fixed base assembly, then the structure is simple and stable, but the adaptability to different configurations (standing vs table-top) is limited
Solution Approach 1:
The fan device is divided into two separate assemblies: a head assembly containing the fan motor and blades, and a base assembly containing the support structure and power supply. These assemblies can be detachably coupled together or separated, allowing the fan to be configured as either a standing fan (with base) or a table-top fan (without base), thereby achieving configuration flexibility without permanently increasing structural complexity.
2Duration of action of moving object
If the fan device includes multiple power sources, then the continuous operation capability is improved, but the device complexity increases
Solution Approach 1:
The base assembly incorporates a rechargeable battery that serves dual functions: it can charge the head assembly's battery when coupled together, and it can also serve as a standalone power source when the assemblies are separated. This multi-functional power supply design enables continuous operation capability without significantly increasing overall device complexity, as the same battery component performs multiple roles.
3Ease of operation
If the receiving portion requires manual alignment, then the coupling mechanism is simple, but the ease of operation deteriorates
Solution Approach 1:
The receiving portion in the base assembly includes guide surfaces that automatically guide the legs of the head assembly into proper alignment during the coupling process. When the user brings the two assemblies together, the guide surfaces passively align the components without requiring manual adjustment or complex alignment mechanisms, achieving ease of operation while maintaining relatively simple device structure.

AI summary
A fan device having a first pedestal configuration and a second table-top configuration is provided. In one embodiment, the fan device includes a head assembly having a fan and a motor operatively coupled to the fan. The head assembly can also include an articulation mechanism and a plurality of legs coupled to the articulation mechanism. The fan device can further include a base assembly having a base and a support with a first end coupled to the base and a second end opposite the first end. The support can include a housing and an elongate receiving portion arranged within the housing at the second end of the support. The receiving portion can be configured to receive the plurality of legs to detachably couple the head assembly to the base assembly.
