Dog-Walking Guidance Vehicle With Feedback Distance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidance vehicles for walking dogs struggle to maintain a consistent distance between the dog and the vehicle, leading to inefficient and uncontrolled walking routes.
Innovation Solution
A guidance vehicle equipped with a leash attachment, distance sensors, and an electronic control unit that executes a walk guidance mode to maintain a constant distance between the dog and the vehicle, using speed control and leash management to ensure the dog stays on the intended route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an automatic unmanned aerial vehicle is used to guide a dog for a walk, then the dog can be guided to walk automatically, but the distance between the dog and the moving body cannot be appropriately controlled
Solution Approach 1:
The patent employs feedback control through distance sensors that continuously measure the distance between the guidance vehicle and the dog, and the electronic control unit adjusts the vehicle's speed based on this feedback to maintain a constant distance. This closed-loop control system resolves the contradiction by enabling both automatic operation and precise distance control.
Solution Approach 2:
The patent replaces manual mechanical control with an electronic control system that uses sensors and automated algorithms to manage the distance between the vehicle and the dog. This substitution enables more precise and consistent distance control compared to manual operation.
2Adaptability or versatility
If the dog is allowed to move freely during the walk, then the dog's natural behavior is maintained, but the dog may deviate from the walk route
Solution Approach 1:
The patent uses dynamic control where the guidance vehicle continuously adjusts its speed and position based on the dog's movements while maintaining the dog on the walk route. The system adapts to the dog's natural behavior patterns while ensuring route consistency through real-time monitoring and control.
Solution Approach 2:
The guidance vehicle acts as an intermediary between the dog's natural movement desires and the requirement to stay on the walk route. It mediates by allowing the dog movement freedom while using the leash attachment and speed control to ensure the dog remains on the designated route.
3Productivity
If the guidance vehicle travels at high speed to improve efficiency, then the walking route coverage increases, but the dog-to-vehicle distance control becomes difficult
Solution Approach 1:
The electronic control unit continuously and periodically adjusts the guidance vehicle's speed based on real-time distance measurements to maintain the constant dog-to-vehicle distance. This periodic control action enables the vehicle to travel efficiently while maintaining precise distance control through continuous monitoring and adjustment.
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 guidance vehicle effectively maintains a constant distance between the dog and itself, allowing for smooth and controlled walking, preventing deviations from the route and ensuring the dog's safety and the owner's convenience.
Implementation Method 1
a distance sensor configured to detect a dog-to-vehicle distance being a distance between the dog and the guidance vehicle

AI summary
A guidance vehicle guides a dog for a walk, and includes a leash attachment, a distance sensor, and an electronic control unit. The leash attachment is configured to attach a leash that connects the dog. The distance sensor is configured to detect a dog-to-vehicle distance being a distance between the dog and the guidance vehicle. The electronic control unit is configured to execute a travel control of the guidance vehicle. The electronic control unit includes, as one of modes of the travel control, a walk guidance mode that causes the guidance vehicle to automatically travel along a walk route while guiding the dog to walk. The walk guidance mode executed by the electronic control unit includes a basic walk mode that controls the dog-to-vehicle distance so as to maintain a constant distance when the dog is moving along the walk route.
