Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chargers with higher power and weight are prone to falling off when plugged into sockets due to gravity and loose connections, leading to a high probability of disconnection.
Innovation Solution
A charger with an auxiliary support assembly that generates a mutual acting force with the socket or its interface, counteracting torque caused by the charger's weight or external forces, using suction cups and telescopic rods to secure the charger in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the charger weight is increased to provide higher power, then the power output is improved, but the charger becomes more prone to falling off due to gravity
Solution Approach 1:
The patent applies the anti-weight principle by introducing an auxiliary support assembly that generates a counteracting force to offset the gravitational effect of the heavy charger body. The support assembly includes components like suction cups or support legs that create upward or stabilizing forces to counterbalance the downward gravitational force, thereby preventing the charger from falling off the socket despite its increased weight for higher power output.
2Power
If the charger body is made heavier for higher power density, then the power density is improved, but the probability of falling off increases
Solution Approach 1:
The patent applies the intermediary principle by introducing an auxiliary support assembly as a mediating structure between the charger body and the socket. This support assembly includes elements like suction cups that can adhere to the socket or surrounding surfaces, or support legs that can extend to provide additional stabilization. These intermediary components transfer and distribute the gravitational load, reducing the direct stress on the plug-socket connection and preventing falling off.
3Ease of operation
If the socket plug interface is loose, then the ease of insertion is improved, but the charger becomes more prone to falling off
Solution Approach 1:
The patent applies the dynamics principle by designing an auxiliary support assembly with movable or adjustable components. The support legs can extend or retract, and the suction cups can adhere or release dynamically. This dynamic capability allows the support assembly to adapt to different socket conditions - providing maximum support when the interface is loose to prevent falling, while not interfering with the ease of insertion when the interface is tight.

AI summary
A charger and a charging system are provided, where the charger includes: a charger body, and an auxiliary support assembly, mounted on the charger body, where the auxiliary support assembly is configured such that when the charger body is plugged into a socket, the auxiliary support assembly is capable of generating a mutual acting force with the socket or an interface on which the socket is located, and the acting force generated by the socket or the interface on the auxiliary support assembly is capable of counteracting or weakening torque generated by the charger body due to gravity of the charger body or an external force. The auxiliary support assembly is disposed on the charger body, so that the mutual acting force generated between the auxiliary support assembly and the socket or the interface on which the socket is located can be used to fasten the charger.
