Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If automated systems use a large number of collection bins to handle diverse objects, then sortation capability is improved, but space requirements and capital costs increase

Engineering Contradiction:
Improvesortation capabilityVSAvoidspace requirements
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The system dynamically reconfigures the number and assignment of collection bins based on real-time sortation needs. The controller can activate or deactivate bins and reassign destinations without physical reconfiguration, allowing the system to handle diverse object types with a reduced physical footprint of bins.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Collection bins serve multiple destinations and object types through dynamic reassignment. A single physical bin can be assigned to different destinations at different times, allowing the same hardware resource to fulfill multiple sortation functions, thereby reducing the total number of bins needed.

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

2Adaptability or versatility

If automated diverts are added to handle more destinations, then sortation flexibility is improved, but mechanical complexity and costs increase

Engineering Contradiction:
Improvesortation flexibilityVSAvoidmechanical complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts the complexity of destination management from the mechanical divert structure. Instead of adding mechanical complexity to handle more destinations, the patent uses a controller that software-manages bin assignments, separating the complexity into the control system rather than the mechanical system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces complex mechanical divert structures with a simplified system using controllers and software-based bin assignment. The mechanical system remains relatively simple while the controller dynamically manages which bins receive objects for which destinations, substituting mechanical complexity with computational logic.

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

3Device complexity

If fixed sequence operations are used for sortation, then process control is simplified, but productivity and efficiency decrease

Engineering Contradiction:
Improveprocess controlVSAvoidthroughput efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system transitions from fixed sequence operations to dynamic, adaptive sequencing. The controller can adjust the sortation sequence based on real-time conditions, object types being processed, and bin availability, optimizing throughput without sacrificing control. The process control remains manageable through software while achieving higher productivity.

Inventive Principle:
Principle #15Dynamics

4Extent of automation

If recirculating conveyors with tilt trays are used, then automated sortation is improved, but difficulty in locating and retrieving specific objects increases

Engineering Contradiction:
Improveautomated sortationVSAvoidobject location tracking
Core Design Contradiction:
Extent of automationVSDifficulty of detecting and measuring

Solution Approach 1:

The system implements feedback mechanisms where the controller tracks which objects have been sorted to which bins. This feedback allows the system to monitor object locations and provide real-time information about bin contents and sortation status, making it easier to locate and retrieve specific objects while maintaining automated sortation.

Inventive Principle:
Principle #23Feedback
