Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual sorting methods are used, then sorting accuracy can be maintained, but productivity is low and labor costs are high

Engineering Contradiction:
Improvesorting speedVSAvoidsorting system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical sorting with an automated system that uses optical detection (cameras) to identify bottle types and mechanical actuators (pneumatic or robotic) to execute sorting actions. This substitution enables high-speed automated sorting while maintaining accuracy through image recognition technology.

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

Solution Approach 2:

The sorting system is designed to automatically detect, identify, and sort bottles without human intervention. The system uses its own integrated sensors and actuators to perform the entire sorting process autonomously, maximizing productivity while reducing labor requirements.

Inventive Principle:
Principle #25Self-service

2Productivity

If bottles are sorted by type, then cleaning efficiency improves, but time for sorting increases

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidsorting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs bottle type identification and sorting decisions in advance, before bottles reach the cleaning area. By detecting and categorizing bottles at the point of entry using optical sensors, the system pre-determines sorting paths and groupings, enabling rapid processing without delaying cleaning operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sorting process is designed to continue without interruption as bottles flow through the system. Multiple sorting stations operate simultaneously and in sequence, with bottles being continuously detected, identified, and sorted in a streamlined workflow that eliminates idle time and maintains constant productive action.

Inventive Principle:
Principle #20Continuity of useful action

3Quantity of substance

If damaged and foreign bottles are included in sorting, then quantity of bottles processed increases, but sorting precision decreases

Engineering Contradiction:
Improvetotal bottles processedVSAvoidsorting accuracy
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The optical detection system is designed to identify specific local characteristics of bottles such as shape, color, and structural features that distinguish valid bottles from damaged or foreign objects. By focusing detection on these localized visual properties, the system maintains high sorting accuracy even when processing large quantities of mixed bottles.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system incorporates feedback mechanisms where detected bottle characteristics are continuously analyzed and compared against predefined criteria. This feedback loop enables real-time adjustment of sorting decisions, ensuring that damaged or foreign bottles are correctly identified and separated while maintaining high processing throughput.

Inventive Principle:
Principle #23Feedback
