Solution Overview

Problem

Existing robotic systems for collecting rollable objects, such as tennis balls, are not energy-efficient, require significant power for operation, and lack convenient access mechanisms after collection, leading to user inconvenience and energy depletion.

Innovation Solution

A lightweight autonomous robot capable of transitioning between horizontal and upright positions, equipped with a rotating collector and a holding basket, uses a low-energy mechanism to collect and store rollable objects, allowing easy access to the collected items by elevating them to a convenient height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If robotic collectors use mechanisms to lift and store balls at a height convenient for later use, then convenient access to balls is improved, but energy consumption increases significantly

Engineering Contradiction:
Improveconvenient access to ballsVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

Instead of using power-consuming mechanisms to lift the ball storage container to a convenient height, the patent inverts the approach by allowing the entire robot to be tilted upright. This passive tilting mechanism uses gravity and user leverage rather than active motors, dramatically reducing energy consumption while still providing convenient access to stored balls.

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

Solution Approach 2:

The robot's chassis serves multiple functions: it acts as both the structural base for autonomous navigation and collection, and simultaneously functions as a tiltable support structure that elevates the ball storage container to an accessible height when upright. This multi-functionality eliminates the need for separate lifting mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If robotic collectors deploy collection mechanisms to collect balls, then ball collection capability is improved, but energy efficiency deteriorates

Engineering Contradiction:
Improveball collection capabilityVSAvoidenergy efficiency
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces traditional high-energy mechanical collection mechanisms (such as rotating brushes or suction systems) with a simpler, lower-energy mechanical approach. The collection mechanism uses the robot's motion and gravity-assisted transfer to move balls into the storage container, significantly reducing power requirements while maintaining effective collection capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If robotic collectors use efficient algorithms for ball location, then collection efficiency is improved, but energy waste from inefficient travel patterns is reduced

Engineering Contradiction:
Improvecollection efficiencyVSAvoidenergy waste from travel
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The robot employs sensors and algorithms that provide real-time feedback about ball locations, allowing the control system to dynamically adjust the robot's travel path. This feedback mechanism enables the robot to navigate directly to areas where balls are detected, avoiding unnecessary travel and reducing energy waste from inefficient collection patterns.

Inventive Principle:
Principle #23Feedback
