Stroller Detachable Auxiliary Power Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers lack a power source, resulting in manual pushing and pulling, which can be physically burdensome, especially when navigating slopes or long distances, and the integrated motor and tire system is costly to replace due to tire wear.
Innovation Solution
A detachable auxiliary power structure for strollers, comprising a power control module with a drive motor, deceleration mechanism, and battery unit, allowing for adjustable speed and braking, with a wheel-motor separation/combination module that enables separate replacement of tires and motor components, reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integrated motor and tire system is used in the stroller, then the stroller can be electrically driven to reduce manual effort, but the cost of replacement increases when the tire wears out
Solution Approach 1:
The power wheel assembly is divided into separable components: the motor unit (with wheel rim) and the tire. The motor unit can be detached from the tire through a quick-release mechanism, allowing the tire to be replaced independently without replacing the expensive motor component. This segmentation resolves the contradiction by enabling cost-effective tire replacement while maintaining the electrically-driven functionality.
2Ease of repair
If a detachable auxiliary power structure is added to the stroller, then maintenance cost decreases due to separate replacement of tires, but device complexity increases
Solution Approach 1:
The power control module incorporates a deceleration mechanism with adjustable damping force, allowing the system to adapt dynamically to different terrain conditions and usage scenarios. This dynamic adjustment capability enables the complex structure to optimize performance while maintaining ease of maintenance through the detachable design.
3Productivity
If the stroller is designed to be electrically driven with adjustable speed, then productivity increases by reducing physical burden, but device complexity increases due to motor and control systems
Solution Approach 1:
The power control module features automatic speed regulation and terrain-adaptive deceleration control that operate without constant user intervention. The system self-adjusts based on detected conditions, reducing the complexity of manual control while maintaining high productivity benefits for the user.
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 detachable power structure reduces human effort required for strolling, especially on slopes, and allows for cost-effective maintenance by enabling individual replacement of tires, enhancing usability and reducing operational expenses.
Implementation Method 1
the brake shoe that is circular is expanded outward to respectively rub against an inner surface of the brake drum that rotates with the tire to force the brake drum and the tire to slow down until the rotation is stopped

AI summary
Disclosed is a stroller with detachable auxiliary power structure, which includes a stroller body, a power control module, and a battery unit. The stroller body includes a front wheel member, a rear wheel member, a left folding member, and a right folding member. Front ends and rear ends of the right and left folding frames are pivotally connected to the front wheel member and the rear wheel member, respectively. The power control module is mounted to a bottom of the rear wheel member and includes a drive motor that outputs a rotational speed and a torque, a gear box, and a power output shaft that has one end connected to the gear box and an opposite end connected to the rear right wheel or the rear left wheel. The battery unit is connected to the drive motor to serve as a power source.
