Connector Structure for Electric Mobility Seat Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mobility devices face challenges in easily connecting and disconnecting connectors between the mobility body and seat unit, especially when the seat height is adjustable, due to the weight and size constraints, making it difficult to load them onto smaller vehicles and requiring complex and costly elevation mechanisms.
Innovation Solution
A connector structure with a first connector attached to the seat unit and a second connector attached to the seat attachment member, positioned to connect below the first connector, utilizing a guide mechanism and magnetic force for easy alignment and connection, allowing for adjustable seat height without compromising connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat height is made adjustable to improve adaptability, then the adaptability is improved, but the device complexity increases due to the need for elevation mechanisms
Solution Approach 1:
The connector is divided into two separate parts: a first connector attached to the seat unit and a second connector attached to the seat attachment member. This segmentation allows the connectors to be positioned independently, enabling easy connection and disconnection without requiring complex elevation mechanisms when the seat height is adjusted.
2Ease of operation
If the connectors are made easily connectable to improve ease of operation, then the ease of operation is improved, but the connection reliability may worsen without proper alignment mechanisms
Solution Approach 1:
The second connector is pre-positioned on the seat attachment member at a location that ensures it will be below the first connector when the seat unit is attached. This preliminary positioning arrangement ensures that the connectors align properly for reliable connection while maintaining ease of operation.
Solution Approach 2:
The seat attachment member acts as an intermediary that carries the second connector and positions it relative to the first connector. This intermediary structure ensures proper alignment and reliable connection between the two connectors while allowing for easy attachment and detachment of the seat unit.
