Solution Overview

Problem

Existing pet ball launchers waste energy and produce noise due to continuous operation, affecting battery life and user comfort.

Innovation Solution

An intelligent sensing ball launcher equipped with sensors to detect the presence of a person or animal, controlling the ball-launching mechanism only when needed, thereby reducing unnecessary driver operation and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the driver continuously drives the ball-launching wheel to rotate, then the ball launcher can continuously launch balls, but energy is wasted and battery life is affected

Engineering Contradiction:
Improveball launching frequencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The ball-launching wheel operates periodically rather than continuously. The driver is activated only when the sensor detects a person or animal approaching, creating intermittent operation cycles that reduce energy consumption while maintaining ball-launching capability when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

A sensor provides feedback about the presence of a person or animal to the control system. This feedback mechanism enables the driver to activate only when necessary, optimizing energy usage by preventing continuous operation and extending battery life.

Inventive Principle:
Principle #23Feedback

2Productivity

If the driver continuously drives the ball-launching wheel to rotate, then the ball launcher can continuously launch balls, but noise is produced continuously, reducing comfort of people and pets

Engineering Contradiction:
Improveball launching frequencyVSAvoidnoise
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The ball-launching wheel operates periodically rather than continuously. The driver is activated only when the sensor detects a person or animal approaching, creating intermittent operation cycles that reduce noise production during periods when no interaction is needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

A sensor provides feedback about the presence of a person or animal to the control system. This feedback mechanism enables the driver to activate only when necessary, optimizing noise reduction by preventing continuous operation and improving comfort for people and pets.

Inventive Principle:
Principle #23Feedback

3Duration of action of moving object

If the driver continuously drives the ball-launching wheel to rotate, then the ball launcher can continuously launch balls, but the operational duration of the driver increases, reducing battery life

Engineering Contradiction:
Improveball launching durationVSAvoidbattery life
Core Design Contradiction:
Duration of action of moving objectVSDuration of action of stationary object

Solution Approach 1:

The ball-launching wheel operates periodically rather than continuously. The driver is activated only when the sensor detects a person or animal approaching, creating intermittent operation cycles that extend battery life by reducing the total operational duration of the driver.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

A sensor provides feedback about the presence of a person or animal to the control system. This feedback mechanism enables the driver to activate only when necessary, optimizing battery life by preventing continuous operation and extending the operational lifespan of the product.

Inventive Principle:
Principle #23Feedback

AI summary

An intelligent sensing ball launcher is provided, including a housing, a ball-launching wheel, a driver, a processor, and a first sensor. The housing is provided with a ball entry port, a ball-launching port, and a slideway. The ball-launching wheel is disposed inside the housing, extends partially into the slideway, and configured to launch a ball passing through the slideway from the ball-launching port. The processor is electrically connected to the driver and configured to control a switching of the driver to drive the ball-launching wheel to rotate. The first sensor is disposed on the housing, electrically connected to the processor, and configured to sense whether or not a person or an animal is approaching. When sensing the person or the animal is approaching, the first sensor feeds back information to the processor, and then the processor controls the driver to operate to drive the ball-launching wheel to rotate.
