Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable power plugs have complex connection structures that complicate assembly and do not effectively address the issue of larger plugs blocking adjacent power sockets, leading to idle sockets when multiple sockets have constant spacings.
Innovation Solution
A rotatable power plug assembly comprising a first connection module with conductive pins, a second connection module with arc-shaped guide grooves, and a plug module with electrical units, allowing for modular design, simple assembly, high durability, and secure electrical connections, enabling the plug to rotate and fit into various socket types without obstructing adjacent sockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable connection is provided between the power cord and the prongs using a rotative coupling device with concentrically arranged annular contacts, then the housing can be biased subject to the position change of the electric appliance, but the connection structure between the power cord and the rotative coupling device becomes complicated
Solution Approach 1:
The invention divides the connection system into separate modules: a power cord connection module with male-female plug interfaces and a housing connection module with conductive pins and receptacles. This segmentation eliminates the need for complex rotative coupling devices while maintaining adaptability to position changes through modular reconfigurability.
Solution Approach 2:
The connection modules are designed with universal interfaces that can accommodate different connection configurations. The male and female plugs, along with conductive pins and receptacles, can be arranged in various patterns to adapt to different appliance positions and orientations without requiring complex rotational mechanisms.
2Reliability
If a power plug with relatively larger volume (adaptor plug) is inserted into a plug socket, then the power plug can provide power connection, but it frequently blocks the insertion holes of adjacent plug sockets, causing them to become idle
Solution Approach 1:
The connection modules are designed to be reconfigurable and adaptable rather than fixed. The male and female plugs can be connected in different orientations and configurations, allowing the system to dynamically adapt to available socket spaces and avoid blocking adjacent sockets while maintaining reliable power connection.
3Adaptability or versatility
If multiple plug sockets are disposed with constant spacing, then small-sized plugs can be inserted without interfering with one another, but larger adaptor plugs cannot be accommodated without blocking adjacent sockets
Solution Approach 1:
The invention segments the power connection system into separate, modular connection units that can be independently configured. This allows each module to be optimized for its specific function while maintaining overall system flexibility, enabling accommodation of different plug sizes without requiring complex socket arrangements.
Solution Approach 2:
The connection modules are designed with universal compatibility features, allowing the same basic module design to accommodate various plug sizes and types through different connection configurations and orientations, eliminating the need for multiple specialized socket types.
