Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical plugs lack the ability to rotate, necessitating fixed power cord directions and often have a large thickness that obstructs furniture placement, due to their fixed orientation and bulkiness.
Innovation Solution
A rotary electrical plug design featuring a rotary base with coaxially integrated first and second conductive circular portions, allowing inserts and connection lugs to rotate, reducing thickness by utilizing internal space efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical plug uses a conventional fixed structure, then the manufacturing and assembly are simple, but the power cord direction cannot be changed and the plug thickness is large
Solution Approach 1:
The patent applies the dynamics principle by making the plug body rotatable relative to the power cord through a rotary base structure. The plug body can rotate 360 degrees around the power cord axis, enabling dynamic adjustment of the power cord direction. This resolves the contradiction by introducing rotational freedom while maintaining a relatively simple overall structure through the use of a rotary base and limiting grooves.
2Volume of moving object
If the electrical plug uses a conventional fixed structure, then the structural design is simple, but the plug thickness is large and obstructs furniture placement
Solution Approach 1:
The patent applies the dimensionality change principle by transitioning from a fixed linear arrangement to a rotational three-dimensional structure. The plug body can rotate around the power cord axis, utilizing the radial dimension to reduce the effective thickness protruding from the wall. This allows furniture to be placed closer to the wall without obstruction, while the rotational mechanism maintains structural simplicity through the rotary base design.
3Ease of operation
If the electrical plug allows rotation, then the power cord direction can be adjusted flexibly, but the structural complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the plug body rotatable relative to the power cord through a rotary base structure. The plug body can rotate 360 degrees around the power cord axis, enabling dynamic adjustment of the power cord direction. This resolves the contradiction by introducing rotational freedom while maintaining a relatively simple overall structure through the use of a rotary base and limiting grooves.
Solution Approach 2:
The patent applies the self-service principle through the limiting groove structure that automatically guides and limits the rotation of the plug body. The limiting grooves on the rotary base and corresponding limiting structures on the power cord work together to self-regulate the rotation range and direction, eliminating the need for complex control mechanisms while ensuring proper operation.
