Solution Overview

Problem

Existing storage systems with charging stations for remotely operated vehicles are inefficient due to the time-consuming process of moving robots between charging stations, which increases the robot's size and reduces the cavity size for storage bins, especially in compact designs.

Innovation Solution

A storage system with a power source transport device that includes a vertically movable lift and horizontally movable support with connecting pins, allowing for efficient relocation of power sources between the robot and charging stations, reducing the need for auxiliary power sources and minimizing space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the robot is equipped with an auxiliary power source to move between charging stations, then the robot can autonomously relocate to charging stations, but the robot size increases and cavity size for storage bins decreases

Engineering Contradiction:
Improveautonomous relocation capabilityVSAvoidrobot cavity size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The auxiliary power source and charging functionality are extracted from the robot and relocated to the charging station infrastructure. The charging station now houses multiple power sources that can service multiple robots, eliminating the need for each robot to carry its own auxiliary power source for relocation purposes.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A power source transport device acts as an intermediary between the robot and charging stations. This device automatically transfers power sources between robots and charging stations, enabling robot relocation without requiring the robot to have its own auxiliary power source.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple charging stations are distributed across the storage system, then robots can access charging stations, but the time required for robots to move between charging stations increases

Engineering Contradiction:
Improvecharging accessibilityVSAvoidrelocation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The power source transport device serves as an intermediary that eliminates the time-consuming step of robot relocation. It automatically retrieves power sources from charging stations and delivers them to robots, or vice versa, without requiring the robot to physically move to the charging station.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The charging function is segmented into multiple independent charging stations distributed throughout the storage system. Each charging station can independently service robots, and the power source transport device can selectively service any station, allowing parallel charging operations and reducing wait times.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If charging stations are fixed to the base in accessible positions, then robots can reach charging stations, but the overall system area required increases

Engineering Contradiction:
Improvecharging station accessibilityVSAvoidsystem footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The power source transport device introduces vertical movement dimension to the charging architecture. Instead of horizontally distributing charging stations across the base area, the system uses vertical lifting mechanisms to bring power sources to charging positions, effectively utilizing the vertical dimension to reduce horizontal footprint.

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

Solution Approach 2:

The charging station assembly is designed as a multi-functional unit that can service multiple robots sequentially. The power source transport device can transfer power sources between multiple charging stations and multiple robots, making the charging infrastructure serve the entire robot fleet rather than requiring dedicated charging stations for each robot.

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