Detachable Power Assembly for Electric Surfboard Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric surfboards require frequent and laborious charging, as the entire board must be carried to a power source, making it time-consuming and inconvenient to recharge the battery.
Innovation Solution
A power surfboard design featuring a detachable power assembly with a movable operating piece that allows the power assembly to be quickly removed and charged separately from the surfboard body, using a system of fasteners and operating pieces to facilitate easy connection and disconnection for charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rechargeable battery is fixed inside the electric surfboard, then the battery is securely held, but the entire surfboard must be carried to a power source for charging which is time-consuming and laborious
Solution Approach 1:
The battery system is segmented into a detachable power assembly that can be separated from the surfboard body. The power assembly includes a battery pack with fasteners that engage with corresponding fasteners in the surfboard body, allowing quick detachment and attachment without tools. This segmentation enables the battery to be removed and charged separately, eliminating the need to transport the entire surfboard to a power source.
2Ease of operation
If the power assembly is made detachable, then charging becomes convenient and quick, but the connection reliability between power assembly and surfboard body may be compromised
Solution Approach 1:
Multiple fastening mechanisms are merged into a single integrated fastener system. The battery pack includes at least one fastener with a fastening end and a locking end, where the fastening end engages with a corresponding fastener in the surfboard body and the locking end secures the connection. This merged fastening system provides reliable mechanical connection while maintaining ease of detachment, resolving the contradiction between connection reliability and charging convenience.

AI summary
A power surfboard includes a surfboard body defining a first side, a supporting piece including at least one first fastener, and a power assembly. An accommodating groove is defined on the first side of the surfboard body. The supporting piece is arranged in the accommodating groove. The power assembly includes a power housing, an operating assembly, and a power source. The operating assembly includes an operating body, at least one second fastener connected to inner side walls of the operating body, and at least one operating piece arranged on the operating body. The power assembly is detachably arranged in the accommodating groove. When each operating piece is in a first state, each second fastener is connected to a corresponding first fastener. When each operating piece is in a second state, each second fastener is separated from the corresponding first fastener.
