Solution Overview
Problem
Existing power line assemblies for electronic devices, such as electric fans, are limited by their length and positioning, restricting the area of use and causing inconvenience in attachment and detachment, which can lead to accidental power disconnection.
Innovation Solution
A power line assembly with power-supply contacts on both surfaces, allowing for magnetic or pin-and-hole connection, and a built-in battery in the electric fan for dual power supply modes, enabling convenient attachment and detachment, and preventing accidental power loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power line assembly is used with a fixed length and positioning, then the device structure is simple, but the area of use is restricted and attachment/detachment is inconvenient
Solution Approach 1:
The power line assembly is divided into separable components: a power line base with power-supply contacts and an electronic device with power-delivery contacts. This segmentation allows the device to be detached and moved to different locations, expanding the area of use while maintaining structural simplicity through modular design.
Solution Approach 2:
Power-supply contacts are provided on both surfaces (top and bottom) of the power line base, adding a dimensional aspect to the connection capability. This allows the electronic device to be attached from either surface, increasing positioning flexibility and area of use without significantly complicating the device structure.
2Ease of operation
If the power line assembly allows easy attachment and detachment, then the ease of operation is improved, but the reliability of power supply deteriorates due to accidental separation
Solution Approach 1:
Connection structures and connection mating structures are pre-provided on both the power line base and electronic device. These preliminary connection elements ensure that when attachment occurs, the connection is immediately secured, preventing accidental separation while still allowing easy attachment and detachment operations.
Solution Approach 2:
Magnetic structures are used as the connection mechanism, utilizing magnetic field attraction forces. This provides a reliable connection that resists accidental separation while maintaining ease of operation, as the magnetic attraction automatically secures the connection without requiring complex mechanical fastening.
3Adaptability or versatility
If power-supply contacts are provided on both surfaces of the power line base, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The power line base is designed with universal functionality by providing identical power-supply contacts on both surfaces. This multi-functional design allows the base to connect with electronic devices from either surface, maximizing positioning flexibility. The manufacturing complexity is managed by using repetitive, standardized contact structures on both surfaces rather than designing entirely different connection mechanisms.
Applied Scientific Principles
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 solution allows for flexible use of electric fans beyond the power line assembly's reach and ensures reliable power delivery by providing a backup battery mode, reducing the risk of accidental disconnection and enhancing user convenience.
Implementation Method 1
the magnetic structure and the connection mating structure may be fixed to each other by magnetic attraction in response to said either of the surfaces mating the power-delivery assembly
