Solution Overview

Problem

Current autonomous robots face challenges in balancing load distribution and preventing tilting or overturning, especially with heavy components like batteries and display units, which can lead to unstable movement and navigation.

Innovation Solution

The robot design incorporates a main body with a traveling unit, a display unit above the front portion, and a battery positioned to balance loads, using a lower plate, upper plate, and top plate configuration with elongated supporting frames, along with a module supporting plate for a service module, to stabilize the center of gravity and prevent tilting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If heavy components like batteries and display units are installed in the robot, then the robot has sufficient power and functionality, but the load distribution becomes unbalanced causing tilting or overturning

Engineering Contradiction:
Improvebattery capacityVSAvoidload balance
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent applies asymmetry by positioning the battery and display unit at specific asymmetric locations within the robot body. The battery is placed in a battery receiving space with a predetermined position, and the display unit is mounted on a display unit supporting plate at a determined location, creating an asymmetric weight distribution that balances the robot's center of gravity and prevents tilting during movement.

Inventive Principle:
Principle #4Asymmetry

2Quantity of substance

If heavy components like batteries and display units are installed in the robot, then the robot has sufficient power and functionality, but the robot tilts forward or backward during movement

Engineering Contradiction:
Improvebattery capacityVSAvoidmovement stability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent implements counterweight principles by strategically positioning the battery and display unit to act as counterbalancing masses. The battery receiving space and display unit supporting plate are designed to place these heavy components at locations that counterbalance each other, creating a stable center of gravity that prevents forward or backward tilting during the robot's movement and navigation.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Quantity of substance

If the robot structure is designed to accommodate heavy components, then the robot has sufficient power and display capabilities, but the center of gravity becomes unstable

Engineering Contradiction:
Improvebattery capacityVSAvoidcenter of gravity stability
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The patent applies local quality by designing specific receiving spaces and supporting structures at predetermined locations within the robot body. The battery receiving space is positioned at a specific location, and the display unit supporting plate is mounted at a determined position, creating localized weight distribution zones that collectively stabilize the robot's center of gravity while accommodating heavy components.

Inventive Principle:
Principle #3Local quality

AI summary

A robot may include a main body coupled to a traveling unit, a display unit disposed above a front portion of the main body, and a battery incorporated in the main body. The traveling unit may include a wheel having a rotational axis extending in a first direction, and the battery may overlap a vertical plane that extends along the rotational axis. The vertical plane and a center of the battery may be separated by a prescribed distance in a second direction that is orthogonal to the first direction.
