Surfboard Battery Housing Handle Lock for Secure Vertical Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically powered surfboards face issues with accidental disengagement of the battery housing due to minor deformations, leading to loss of electrical contact and control, and require wide recesses for secure grip, which can be hazardous. Additionally, current battery housings are difficult to handle due to horizontal orientation.
Innovation Solution
A surfboard design featuring a battery housing with a bracket handle and a handle lock/latch system, allowing the battery housing to be oriented vertically for easier handling, and a biasing force to move the bracket handle out of the recess when disengaged, enabling a secure grip and narrow recess geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wide recess is provided for secure grip of the bracket handle, then ease of operation is improved, but the risk of toe entrapment and device complexity increases
Solution Approach 1:
The patent transitions from a wide recess configuration to a narrow recess configuration by changing the spatial arrangement and adding a finger grip element that extends in a different dimension (upwards), providing secure grip without requiring wide horizontal space
2Ease of operation
If a wide recess or finger grip is provided for secure grip, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The grip function is segmented into two parts: the bracket handle itself and the separate finger grip element, allowing each to be optimized independently - the handle for manipulation and the finger grip for secure holding
3Ease of manufacture
If the battery housing is oriented horizontally, then manufacturing is simplified, but ease of operation deteriorates
Solution Approach 1:
The patent makes the battery housing orientation dynamic by providing means to reposition it from horizontal to vertical orientation, allowing optimal handling position while maintaining manufacturing simplicity in the base configuration

AI summary
A surfboard including a surfboard body and having an upper surface and a bottom surface, an upwardly open cavity formed in the upper surface, an electric drive for propelling the surfboard, a battery housing having an upper face and being connected with the electric drive for supplying electrical energy, the upper face having a recess extending between opposite side faces of the battery housing, the battery housing being removably received in the cavity. A bracket handle with a central portion and opposite side portions defining arms pivotally mounted to the battery housing to allow turning of the bracket handle between a carrying position for carrying the battery housing when removed from the cavity and a second position wherein the central portion is nested within the recess. The battery housing having a latching portion in releasable engagement with the central portion when nested within the recess.
