Solution Overview

Problem

Existing multi-layer container robots inefficiently utilize their components, as the fork remains idle even when the pack baskets are fully loaded, limiting the handling capacity and efficiency of goods transportation.

Innovation Solution

A method and apparatus for controlling robots with liftable forks and pack baskets, allowing simultaneous use of both to enhance handling capacity by loading goods onto the fork and pack baskets, optimizing movement and placement of goods at multiple stop positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the robot uses only pack baskets for goods handling, then the structure is simple, but the handling capacity is limited when pack baskets are fully loaded

Engineering Contradiction:
Improvehandling capacityVSAvoidcomponent utilization
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the fork multi-functional by enabling it to both transport goods directly to destination and serve as temporary storage during robot movement. The fork can hold goods while the robot navigates to target positions, effectively combining transportation and temporary storage functions into a single component, thereby increasing overall handling capacity without adding new components.

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

Solution Approach 2:

The patent implements preliminary action by loading the fork with goods before the robot begins movement to the target position. This allows the fork to be prepared in advance with goods that will be needed at the destination, enabling smoother operations and reducing waiting time at destination points, thus improving handling capacity.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the robot waits for pack baskets to be emptied before returning to goods-taking position, then goods are placed correctly, but time is lost and efficiency decreases

Engineering Contradiction:
Improvehandling efficiencyVSAvoidrobot idle time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent achieves continuity of useful action by enabling the robot to transport goods using the fork during movement between positions, rather than idle waiting. The fork-loaded goods are transported continuously during robot navigation, eliminating idle time and ensuring the robot is constantly engaged in productive activities, thereby improving handling efficiency.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent applies preliminary action by pre-loading the fork with goods before robot movement begins. This preparation ensures that goods are ready for immediate placement at the destination, eliminating the need for the robot to wait at the destination for pack baskets to be emptied, thus reducing idle time and improving efficiency.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the robot transports goods only in pack baskets, then loading is straightforward, but the robot cannot fully utilize its components during movement

Engineering Contradiction:
Improvecomponent utilizationVSAvoidcontrol complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enhances component utilization by making the fork serve dual purposes: traditional goods manipulation and temporary goods storage during transport. This multi-functionality ensures that the fork remains actively engaged throughout robot operations, maximizing component utilization without requiring additional specialized components.

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

Solution Approach 2:

The patent implements dynamics by making the fork's function adaptable based on operational context. The fork dynamically switches between traditional manipulation tasks and temporary storage roles depending on the robot's operational state, allowing flexible adaptation to different operational requirements while maintaining high component utilization.

Inventive Principle:
Principle #15Dynamics
