Motorized Pet Stroller Treadmill Kinetic Energy Harvesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet strollers either fail to provide adequate exercise for pets or are difficult for dog walkers to manage due to size or energy limitations, as they either offer little to no exercise or require manual effort without motorized assistance.
Innovation Solution
A pet stroller equipped with a motorized treadmill, rechargeable battery, and adjustable speed control, allowing pets to walk or run while harnesses ensure safety, and kinetic energy from user or pet movement can recharge the battery, enabling motorized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motorized treadmill is added to the stroller, then exercise quality is improved, but device complexity increases
Solution Approach 1:
The treadmill mechanism is integrated within the stroller frame, merging the exercise function with the transportation function. The motor, belt, and supporting structure are combined into a single unified assembly that fits within the stroller's existing spatial constraints, providing motorized exercise without requiring a separate device.
Solution Approach 2:
The stroller serves multiple functions: it transports the dog during walks and simultaneously provides a motorized treadmill for exercise. The motorized belt system allows the dog to exercise while being transported, eliminating the need for separate exercise equipment and enhancing the overall utility of the stroller.
2Extent of automation
If battery power is used for the motor, then automation is improved, but energy consumption increases
Solution Approach 1:
The system generates its own power through the motion of the treadmill belt itself. As the belt moves and rotates, it drives a generator that produces electrical energy to charge the battery. This self-powering mechanism reduces the need for external energy sources and minimizes energy consumption from the user.
Solution Approach 2:
The battery provides continuous power to the motor throughout the stroller's operation, enabling uninterrupted motorized treadmill function. The recharging mechanism ensures the battery is continuously maintained, allowing prolonged automated operation without requiring frequent interruptions for recharging.
3Loss of energy
If kinetic energy harvesting is implemented, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The system converts the kinetic energy that would otherwise be wasted during treadmill operation into useful electrical energy. The motion of the belt, which naturally occurs during dog exercise, is harnessed to generate power through a generator, transforming a potentially wasteful energy loss into a beneficial charging source for the motor system.
Solution Approach 2:
A generator acts as an intermediary component between the treadmill belt and the battery system. The generator converts the mechanical kinetic energy from the moving belt into electrical energy, serving as a bridge that transfers energy from one form to another and enables efficient energy storage and reuse within the system.
4Adaptability or versatility
If speed control is made adjustable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The treadmill belt speed is made dynamically adjustable, allowing the motor to vary the belt speed according to the dog's exercise needs and walking pace. This dynamic control enables the system to adapt to different exercise intensities, from gentle walks to more vigorous runs, providing versatility in the exercise experience.

AI summary
The inventive subject matter provides a device in which a pet stroller comprises at least three wheels, a battery, a motor, and a treadmill. The treadmill is positioned inside of the stroller and has a belt upon which an animal walk and run. The battery is configured to power the motor, and in at least some contemplated embodiments, movement of one or more of the wheels of the stroller can be used to directly move the belt of the treadmill, and/or indirectly power the belt by providing power to the battery.
