Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual judgment by worker is used to determine locked state, then device complexity is reduced, but reliability and measurement precision deteriorate

Engineering Contradiction:

Improvestructure complexityVSAvoidlocked state detection reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces the manual mechanical judgment method with an electronic detection system consisting of a microswitch, elastic piece, and sensor. The microswitch automatically detects whether the discharge disc is properly locked by sensing the position of the elastic piece, which is driven by the interaction between the discharge disc and housing. This substitution of mechanical manual inspection with an electronic sensing system resolves the contradiction by providing reliable automated detection without significantly increasing overall device complexity.

If manual judgment by worker is used to determine locked state, then device complexity is reduced, but measurement precision deteriorates

Engineering Contradiction:

Improvestructure complexityVSAvoidlocked state detection precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces subjective manual judgment with an objective electronic sensing system. The microswitch precisely detects the locked state by sensing the position of the elastic piece, which is driven by the mechanical interaction between the discharge disc and housing. This provides accurate binary detection (locked/unlocked) without the errors associated with human judgment, resolving the measurement precision issue while maintaining relatively simple device structure.

3Reliability

If microswitch detection system is added, then reliability and measurement precision improve, but device complexity increases

Engineering Contradiction:

Improvelocked state detection reliabilityVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a microswitch detection system that uses an elastic piece as a mechanical intermediary. The elastic piece is driven by the mechanical interaction between the discharge disc and housing, and the microswitch simply detects the position of this elastic piece. This design keeps the added complexity minimal by using a simple elastic-driven mechanism rather than a complex sensing system, while still achieving reliable automated detection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The elastic piece serves as an intermediary element between the mechanical locking structure and the microswitch sensor. It translates the mechanical state of the discharge disc into a positional change that the microswitch can detect, allowing reliable detection without requiring direct complex interaction between the locking mechanism and the sensor.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent uses a microswitch detection system with an elastic piece to automatically monitor the locked state of the discharge disc. This electronic detection system provides operational safety by ensuring the discharge disc is properly locked before operation, preventing leakage and damage. The complexity is kept manageable by using a simple elastic-driven mechanical-to-electrical conversion mechanism rather than a complex control system.
