Solution Overview

Problem

Existing robot systems face challenges in safely and efficiently transporting items between indoor and outdoor environments, particularly in delivering items from a station body to a destination while maximizing the size of items that can be stored.

Innovation Solution

A robot system comprising a station body with guide rails and robots that move in different directions, including a first robot with a lifter and a second robot with a seating body, allowing for efficient item transfer and charging mechanisms, along with a pusher and conveyor for item handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single robot moves items in one direction, then the structure is simple, but the transportation efficiency and storage capacity are limited

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidrobot system structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The robot system is divided into multiple independent robots (first robot with lifter, second robot with seating body) that operate on separate guide rails. Each robot handles specific transportation tasks in different directions, allowing parallel operations and improved overall productivity without requiring a single complex robot structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from single-direction linear transportation to multi-dimensional transportation by adding robots that move in different directions (first direction and second direction perpendicular to each other) on different guide rails, enabling more efficient item routing and station utilization.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If guide rails are positioned at higher levels, then item access is easier, but the storage space within the station body is reduced

Engineering Contradiction:
Improveitem accessVSAvoidstorage space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The system uses vertical stacking of guide rails at different heights (first guide rail at first height, second guide rail at second height lower than first) to create multi-level transportation pathways. This allows items to be accessed from multiple vertical levels simultaneously, maintaining ease of operation while maximizing the use of vertical space for storage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The second robot with seating body is positioned at a lower height and can accommodate the first robot when not in use. This nested arrangement allows both robots to coexist in a compact configuration, optimizing space utilization within the station body while maintaining access to items at different heights.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Speed

If multiple robots operate simultaneously, then transportation speed increases, but the risk of collision and system failure increases

Engineering Contradiction:
Improvetransportation speedVSAvoidsystem safety
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system separates multiple robots onto different guide rails (first guide rail for first robot, second guide rail for second robot) that are positioned at different heights and orientations. This spatial segmentation prevents physical collisions between robots while allowing them to operate simultaneously at high speeds, maintaining system safety through physical isolation of movement paths.

Inventive Principle:
Principle #1Segmentation
