Solution Overview

Problem

Traditional bicycles limit upper body motility and reduce sport and fitness effects, leading to decreased amusement and reduced usage over time due to their conventional pedaling mechanism.

Innovation Solution

A direct-drive double wing scooter design featuring a frame with actuation and drive assemblies, including swing wings, turning shafts, gears, and a one-way sprocket wheel, allowing for a unique pedaling motion that enhances fitness and amusement by providing a different drive mechanism compared to traditional bikes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional bike uses a seat to support the rider for continuous circular pedaling, then the rider can tread on the pedals smoothly and safely, but the motility of the upper part of the body is reduced and sport and fitness effects are diminished

Engineering Contradiction:
Improvepedaling smoothness and safetyVSAvoidupper body motility and fitness effect
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention inverts the traditional pedaling approach by replacing the seated continuous circular motion with a standing swing wing motion. Instead of sitting on a seat and rotating pedals, the rider stands and swings wings alternately, transforming the passive seated position into an active standing posture that engages the upper body while maintaining safe and smooth operation through the swing wing mechanism

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention applies dynamics by replacing the static seated position with a dynamic standing posture and alternating swing motion. The swing wings move alternately in a dynamic fashion, engaging different muscle groups and providing continuous upper body motility, while the mechanical linkage ensures smooth and safe operation throughout the motion cycle

Inventive Principle:
Principle #15Dynamics

2Productivity

If a traditional bike uses continuous circular pedaling to drive the wheels, then the bike can move forward efficiently, but the drive mechanism is complex and reduces amusement value

Engineering Contradiction:
Improveforward motion efficiencyVSAvoiddrive mechanism complexity and amusement value
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts the essential function of forward motion from the complex traditional drivetrain (chain, gears, pedals) and replaces it with a simplified swing wing mechanism. The alternation between the two swing wings directly drives the rear wheel through a simpler linkage, removing unnecessary components while maintaining efficient forward motion and increasing amusement value through the novel drive approach

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a complex chain-and-gear system to convert circular pedal motion into wheel rotation, the invention inverts the approach by using alternating linear swing motions to directly drive the wheel. This reversal of the drive mechanism simplifies the system while maintaining productivity and enhancing amusement through the unique motion pattern

Inventive Principle:
Principle #13The other way round (Inversion)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The scooter offers a simple and reliable drive method that enhances transportation, amusement, and fitness effects by allowing complementary swing wings to operate without jamming, improving riding safety and comfort through adjustable included angles and inclined step sections.

Implementation Method 1

The actuation assembly comprises two swing wings each pivoted to the front end of the frame through a pivot. The drive assembly comprises a first turning shaft and a second turning shaft. Two ends of the first turning shaft are provided with a pair of cranks having an included angle of 180 degrees. A tail end of each crank is pivotally connected with a third turning shaft to lean against a corresponding one of the right swing wing and the left swing wing.

Methodology Applied
Scientific EffectMechanical Advantage: Mechanical Advantage

Implementation Method 2

One end of the first turning shaft is provided with a first gear. One end of the second turning shaft is provided with a second gear meshing with the first gear. The first gear and the second gear are located at the same side of the frame.

Methodology Applied
Scientific EffectGear Meshing: Gear

Implementation Method 3

The transmission assembly comprises a one-way sprocket wheel located at another end of the second turning shaft opposite the second gear, a third gear disposed at a wheel axle of the rear wheel, and a chain fitted around the one-way sprocket wheel and the third gear.

Methodology Applied
Scientific EffectChain Drive: Chain

AI summary

A direct-drive double wing scooter includes a frame, an actuation assembly, a drive assembly, and a transmission assembly. The actuation assembly includes left and right swing wings each pivoted close to a front end of the frame through a pivot. The drive assembly includes a first turning shaft and a second turning shaft penetrating two sides of the frame. A distance between the first turning shaft and the pivot is defined as a first distance. A distance between a rear end of the right swing wing is defined as a second distance, or a distance between a rear end of the left swing wing is defined as a second distance. The first distance is in the range of 0.10-0.65 times the length of the second distance. The direct-drive double wing scooter provides a simple and reliable drive way and has transportation, amusement and fitness effects.
