Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Longboard users are limited to lower body exercise for propulsion and lack a device to utilize upper body strength for propelling and directing their longboards, especially in navigating varied topography.
Innovation Solution
A telescoping pole with a first and second portion and a wheel assembly, featuring a spinning wheel that rotates perpendicular to the rod, allowing users to apply axial force for propulsion and control, using coiled springs for spring-loaded action and friction management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If users propel longboards by pushing off the ground with their foot, then the longboard can move forward, but users are limited to lower body exercise and cannot utilize upper body strength
Solution Approach 1:
The patent introduces a pole as an intermediary tool between the user and the ground. The pole transfers upper body forces to propel the longboard forward, enabling users to utilize upper body strength while maintaining ease of operation through a simple gripping and pushing motion
2Ease of operation
If users steer the longboard by shifting weight or foot position, then direction can be changed, but users must change foot position which disrupts riding continuity
Solution Approach 1:
The patent makes the pole multi-functional by using it for both propulsion and steering. The same pole that pushes the user forward also serves as a steering mechanism through lateral movements, eliminating the need for separate steering actions and maintaining riding continuity
3Use of energy by moving object
If a telescoping pole with spring mechanism is added for propulsion, then upper body strength can be utilized, but device complexity increases
Solution Approach 1:
The patent employs a telescoping pole where segments are nested within each other, allowing the pole to extend and retract. This nesting principle reduces the stored complexity while maintaining the functional complexity needed for upper body propulsion
Solution Approach 2:
The patent incorporates a spring mechanism that provides dynamic assistance to the user's pushing motion. The spring dynamically adjusts to the user's force application, providing assistance during propulsion while adding minimal structural complexity through its integrated design

AI summary
The invention is directed to a telescoping pole to help direct a longboard comprising a first and second portion. The first portion includes a first end, a second end and a first tubular shaft. A first handle is positioned at the first end, while a second handle is positioned along the first tubular shaft between the first and second end. The second portion also has first end, a second end, and a second tubular shaft (having a diameter less than the first tubular shaft). The first end of the second portion is attached to the first portion through a first coiled spring. A wheel assembly having a spinning wheel is affixed to the second end of the second portion having a third tubular shaft having diameter less than the second tubular shaft. A second coiled spring is placed over the third tubular shaft, which engages the second portion.
