Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual inspection and weighing of packages is performed, then the distribution robot can determine package size and weight, but the process is inconvenient and inefficient

Engineering Contradiction:

Improvepackage inspection efficiencyVSAvoidmanual inspection convenience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The distribution robot performs automatic package inspection using its own integrated sensors (gravity sensing device, contour detection unit, infrared sensors) without requiring external weighing scales or manual measurement tools. The system serves itself by autonomously detecting package parameters and making delivery decisions

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical inspection and weighing operations are replaced by automated sensing systems including gravity sensing devices, contour detection units, and infrared sensing devices that automatically measure package weight, size, and shape without human intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If packages are stuffed into the distribution robot without weight verification, then the delivery process is fast, but the robot runs in overload which affects performance and lifespan

Engineering Contradiction:

Improvedelivery speedVSAvoidrobot performance and lifespan

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The distribution robot performs preliminary weight detection using the gravity sensing device before accepting packages for delivery. This advance checking prevents overload conditions by identifying excessive weight packages beforehand, allowing the system to reject or redistribute them before they compromise robot performance

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The gravity sensing device continuously monitors package weight and provides feedback to the control system. When the total weight approaches or exceeds the robot's carrying capacity, the system receives feedback signals and automatically adjusts by refusing additional packages or redistributing existing ones, preventing overload damage

Inventive Principle:

Principle #23Feedback

3Productivity

If manual weighing and pricing is performed with price manually entered into an applet, then the distribution robot can deliver packages, but the process is cumbersome and inefficient

Engineering Contradiction:

Improvepricing and delivery efficiencyVSAvoidmanual operation complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The distribution robot autonomously performs pricing calculations using its built-in gravity sensing device to measure package weight and automatically compute delivery fees according to preset pricing rules. The system eliminates the need for external weighing scales and manual price entry into mobile applications

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual weighing operations and price entry processes are replaced by an integrated automated pricing system that combines gravity sensing, weight measurement, and automatic fee calculation, eliminating the need for manual intervention in the pricing workflow

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
