Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the bag body detection element is arranged in the vacuumizing groove, then the automatic detection function can be achieved, but the detection element is prone to pollution, corrosion and damage

Engineering Contradiction:

Improveautomatic detection functionVSAvoiddetection element stability

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The bag body detection element is extracted from the vacuumizing groove environment and relocated to the upper switch chamber, separating it from the harmful vacuumizing groove environment while maintaining its detection function. This extraction resolves the contradiction by removing the detection element from the污染源 (pollution source) without eliminating the automatic detection capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The utility model introduces an intermediary structure (the upper switch chamber and its sealing components) between the detection element and the vacuumizing groove. This intermediary protects the detection element from direct exposure to pollutants while still allowing it to perform its detection function, thus resolving the contradiction between automation and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the bag body detection element is arranged in the vacuumizing groove, then the automatic work can be achieved, but the detection element is prone to damage and detection function becomes invalid

Engineering Contradiction:

Improveautomatic work capabilityVSAvoidpollution and corrosion to detection element

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The detection element is extracted from the harmful environment of the vacuumizing groove and placed in the protected upper switch chamber. This extraction maintains the automatic work capability while eliminating exposure to pollution and corrosion, directly resolving the contradiction between ease of operation and resistance to harmful factors.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The utility model converts the potentially harmful vacuumizing groove environment into a beneficial separated zone by using the sealing structure. The harmful factors (pollution, corrosion) are confined to the vacuumizing groove area, while the detection element operates in a clean environment, transforming the harmful situation into a beneficial separation that protects the detection system.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If the bag feeding induction mechanism is arranged above the vacuumizing groove, then the mechanism is protected from damage, but the structure becomes more complex

Engineering Contradiction:

Improvedetection mechanism stabilityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The utility model segments the device into distinct functional zones: the upper switch chamber housing the detection element, and the vacuumizing groove for the sealing operation. This segmentation protects the detection mechanism while maintaining a relatively simple overall structure by clearly defining functional boundaries and using standard sealing components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The upper switch chamber serves as an intermediary structure that adds minimal complexity while providing essential protection. By using a simple sealed chamber design with standard sealing strips and connecting pieces, the structure remains relatively simple while effectively protecting the detection mechanism from damage.

Inventive Principle:

Principle #24Intermediary (Mediator)
