Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual sorting with human workers is used, then flexibility in handling objects of varying sizes and weights is improved, but productivity is reduced

Engineering Contradiction:
Improveflexibility in handling objectsVSAvoidthroughput
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical sorting operations with an automated system using robotic arms equipped with sensors and computer vision. The robotic system can identify objects by their visual characteristics and automatically sort them into appropriate bins, eliminating the need for human workers to manually handle and sort objects while maintaining the ability to accommodate varying sizes and weights through programmable control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables objects to be automatically identified and sorted based on their visual features without human intervention. The robotic arm autonomously detects object characteristics through cameras and sensors, determines the appropriate destination bin, and executes the sorting action independently, creating a self-service automated sorting process.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If a large number of collection bins are used to handle diverse objects, then adaptability is improved, but device complexity and space requirements increase

Engineering Contradiction:
Improveability to handle diverse objectsVSAvoidnumber of collection bins
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic bin assignment where the system can reconfigure which objects go to which bins based on real-time conditions and object characteristics. Rather than having fixed, dedicated bins for each object type, the system dynamically determines destination assignments, allowing the same bin to serve multiple object types at different times and reducing the total number of bins needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The robotic sorting system provides universal functionality by being able to sort any object type into any bin based on visual recognition and programmable logic. The single robotic arm can handle diverse objects of varying sizes and weights and direct them to appropriate bins, replacing the need for multiple specialized sorting mechanisms and reducing overall system complexity.

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

3Measurement precision

If fixed or robot-held code scanners are used, then object identification accuracy is improved, but ease of operation is reduced

Engineering Contradiction:
Improveobject identification accuracyVSAvoidmanual processing requirement
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces manual code scanning operations with automated computer vision systems using cameras and image processing algorithms. The system automatically captures images of objects, identifies visual features and characteristics, and determines object identity and destination without requiring human operators to manually scan codes, thereby maintaining identification accuracy while eliminating manual labor.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates visual copies of objects through camera imaging and uses digital image processing to extract identifying information. Rather than requiring physical interaction with objects or manual code scanning, the system captures optical copies and analyzes them computationally to achieve accurate object identification and sorting decisions.

Inventive Principle:
Principle #26Copying

4Productivity

If actuated diverts are used in conventional sorting systems, then sorting capability is improved, but device complexity and mechanical complexity increase

Engineering Contradiction:
Improvesorting capabilityVSAvoidmechanical complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex actuated divert mechanisms from the sorting system. Instead of using mechanical diverters that require actuators and complex linkages to redirect objects, the system uses a robotic arm to directly pick up objects and place them into the appropriate bins, eliminating the need for intermediate divert mechanisms and significantly reducing mechanical complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The robotic arm serves as an intermediary between object detection and bin placement, replacing the traditional intermediary divert mechanisms. The robotic gripper directly manipulates objects and transfers them to destination bins, eliminating the need for complex actuated divert systems while maintaining sorting capability through intelligent control and positioning.

Inventive Principle:
Principle #24Intermediary (Mediator)
