Powered Boots Chassis and Motor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized surf boots face challenges in transitioning from water to land use, including unstable balance due to excessive degrees of freedom between boards, inadequate support for handheld throttles, and a lack of suitable electric propulsion arrangements for land operation.
Innovation Solution
The design incorporates a connecting chassis to maintain board parallelism and stability, adjustable spring-assisted re-centering for turns, handlebars with damping control for ergonomic steering, and electric motors packaged within wheels or track assemblies for compact, multi-terrain capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid links with pivotable connections are used to connect boards, then the boards are kept at a fixed distance, but the boards can randomly twist longitudinally due to excessive degrees of freedom
Solution Approach 1:
The connection system is segmented into multiple functional components: rigid links for distance maintenance, pivotable connections for articulation, and longitudinal constraints for twist prevention. Each segment performs a specific function to collectively achieve stable board connection without excessive freedom.
Solution Approach 2:
An intermediary constraint mechanism is introduced between the rigid links and boards to prevent longitudinal twisting. This mediator component restricts unwanted degrees of freedom while preserving the necessary pivotable connection for steering and balance.
2Ease of operation
If handheld throttles are supported by a frame network, then the throttles are held in place, but the rider cannot effectively kneel or squat while using them
Solution Approach 1:
The throttle support system transitions from a static frame network to a dynamic arrangement that adapts to rider posture changes. The throttles are positioned and supported in a way that allows the rider to kneel or squat while maintaining stable throttle control, enabling flexible positioning without compromising control reliability.
Solution Approach 2:
Different parts of the throttle support system have different properties: the mounting structure provides stable positioning while the handheld portion allows for natural gripping and maneuvering. This local differentiation enables both stability and rider flexibility simultaneously.
3Volume of moving object
If electric motors are packaged within wheels or track assemblies, then the device becomes compact for land use, but the propulsion system becomes more complex to integrate
Solution Approach 1:
The electric motors are nested within the wheel or track assembly structures, with the motor housing integrated into the wheel rim or track frame. This nesting arrangement minimizes overall volume by eliminating separate motor mounts and reducing structural overhead, achieving compact propulsion while managing integration complexity through unified design.
