Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power connection apparatuses in low-temperature showcases face issues with electrical leakage, rusting, and frost-induced detachment due to humidity and temperature effects, complicating the connection and disconnection process between power plugs and sockets.
Innovation Solution
A power connection apparatus featuring a handle with a grip portion and an abutment portion on the power plug, where the handle is rotatably attached and includes engaging claws that disengageably engage with the power socket's engagement portion, allowing for secure connection and simplified operation by regulating the rotation angle and leveraging principles to facilitate easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle with engaging claws is provided on the power plug to secure connection with the power socket, then the connection reliability is improved, but the operation complexity increases and the connecting operation properties deteriorate
Solution Approach 1:
The handle is designed to be rotatable relative to the power plug body, allowing it to move between a horizontal position for insertion and a vertical position for engagement. This dynamic movement simplifies the connecting operation by enabling the handle to automatically align with the socket opening during insertion, while still providing secure engagement through the engaging claws when in the vertical position.
Solution Approach 2:
The engaging claws are pre-positioned on the handle in a retracted or non-obtrusive state before insertion. During the connecting operation, as the power plug is inserted into the socket, the handle rotates and the engaging claws automatically engage with the engagement portions on the socket. This preliminary positioning of the claws eliminates the need for manual manipulation during insertion, simplifying the operation while ensuring reliable connection.
2Ease of operation
If the handle can rotate downwardly from substantially right angles to facilitate operation from the front side, then the ease of operation is improved, but the handle abutment disturbs and disables further rotation
Solution Approach 1:
The rotation limiting mechanism is designed to prevent the handle from rotating beyond the substantially right angle position. By providing this preliminary restriction, the invention avoids the problem of the abutment portion disturbing or disabling further rotation. The handle is constrained to rotate only to the extent necessary for engagement, eliminating the need for complex multi-stage rotation control while maintaining ease of operation from the front side.
3Reliability
If engagement portions are provided on the power socket and engaging claws on the handle to secure connection, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The connection mechanism is segmented into distinct functional elements: engagement portions on the power socket and corresponding engaging claws on the handle. This segmentation allows each component to be independently designed and positioned optimally for its specific function. The engagement portions are provided on the socket body while the engaging claws are integrated with the handle, creating a modular connection system that achieves reliable engagement without requiring a completely complex integrated structure.
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 secures the connection between the power plug and socket, improves connecting and removal operation properties, and prevents electrical leakage and rust, while also providing a drip-proof cover to protect against humidity and frost.
Implementation Method 1
the connection arm extended with an elasticity and having a tip rotatably supported by the power socket
Implementation Method 2
a pivoting portion positioned between the ends being rotatably attached to the power plug... the handle is rotated in a direction in which the grip portion comes close to the power socket, and the engaging claw engages with the engagement portion

AI summary
There is disclosed a power connection apparatus which can secure connection between a power socket and a power plug and which can simplify the connecting operation properties thereof. A handle rotatably attached to the power plug having terminals includes engaging claw disengageably engaged with engagement portion of the power socket having an electrode portion, an abutment portion which abuts on the power socket, and a grip portion. The rotation of the grip portion in such a direction as to come away from the power socket is limited by the angle of the rotation of the handle in a direction in which the grip portion comes close to the power socket.
