Seated Skateboard Converter With Mid-Pivot Foot Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized skateboards lack a seated riding position with effective foot stabilization and pitch and roll control, leading to operator fatigue and reduced mobility.
Innovation Solution
A seated skateboard ride converter with a parallel-to-ground-plane foot dolly and caster assembly supports foot pegs, connected to a pitch and roll mid pivot, allowing a seat to be mounted above a driven wheel, providing enhanced mobility, safety, and reduced fatigue through controlled pitch and roll movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a seated position is added to the motorized skateboard, then operator fatigue is reduced and safety is improved, but the device complexity increases
Solution Approach 1:
The foot dolly assembly with foot pegs and caster wheels is nested within the overall skateboard structure, connecting to the mid-pivot mechanism. This nested configuration allows the foot stabilization system to be integrated without requiring separate independent structures, thereby reducing overall device complexity while still providing seated positioning and foot support functionality.
Solution Approach 2:
The mid-pivot mechanism serves multiple functions: it enables pitch control, allows roll movement, and provides the mounting point for both the seat and foot dolly assembly. This multi-functionality reduces the need for separate dedicated mechanisms for each function, thereby improving ease of operation while limiting the increase in device complexity.
2Reliability
If foot stabilization is added through a foot dolly and caster assembly, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The caster assembly on the foot dolly provides self-aligning and self-stabilizing functionality. The caster wheels automatically adjust to surface irregularities and provide stable support without requiring active control mechanisms or additional stabilization systems. This self-service capability improves operator safety through reliable foot support while avoiding the need for complex active stabilization systems.
3Speed
If pitch and roll control is maintained with a mid-pivot mechanism, then mobility is improved, but the device complexity increases
Solution Approach 1:
The mid-pivot mechanism provides dynamic pitch and roll control that adapts to operator input and terrain conditions. The mechanism allows continuous adjustment of the skateboard's orientation in both pitch and roll axes, enabling responsive and flexible mobility control. This dynamic capability improves mobility by allowing smooth transitions and adaptive control while the mechanical pivot design keeps the implementation relatively simple compared to electronic or hydraulic alternatives.
