Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional mechanical sortation systems are used to handle objects of varying sizes and weights, then sorting capability is improved, but device complexity and cost increase due to requiring numerous collection bins and extensive mechanical diverts

Engineering Contradiction:

Improvesorting capabilityVSAvoidmechanical complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical sortation systems with a vacuum-based system. Instead of using numerous mechanical diverts and collection bins, the invention uses vacuum forces applied through conveyor sections to selectively retain or release objects based on their mass and surface area characteristics, thereby simplifying the mechanical complexity while maintaining sorting capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention employs pneumatic principles by using vacuum rollers and vacuum forces to manipulate objects during sorting. The vacuum system creates selective adhesion forces that allow objects of different masses and surface areas to be sorted into fixed-size collection bins without requiring complex mechanical structures

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If human workers perform object induction and sorting, then flexibility in handling dissimilar objects is improved, but labor costs and operational inefficiency increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The vacuum sortation system operates autonomously to perform object induction and sorting without human intervention. The system automatically detects object characteristics and applies appropriate vacuum forces to sort objects into correct bins, eliminating the need for human workers while maintaining flexibility in handling dissimilar objects and improving operational efficiency

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If numerous collection bins are used to handle varying object types, then sorting precision is improved, but space requirements and system cost increase

Engineering Contradiction:

AI summary

In an induction system for use with an object processing system, a distribution system is disclosed for providing dissimilar objects into one of a plurality of receiving units. The distribution system includes a conveyor section that travels over a vacuum roller, and the plurality of receiving units arranged generally below the vacuum roller such that an object with a mass will fall toward one of the plurality of receiving units based on both the object's mass and a vacuum force applied to the object through the conveyor section.
