VSEngineering Contradiction Analysis

1Reliability

If manual welding and threading of wires is used for electrical connections, then reliable electrical connection is achieved, but production process becomes complex and time-consuming

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual welding process with a mechanical insertion and elastic abutment system. The first electrode pin is simply inserted into the bayonet socket, and the elastic connection end of the first electrode provides automatic electrical contact through elastic abutment, eliminating the need for welding operations while maintaining reliable electrical connection.

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

Solution Approach 2:

The elastic connection end of the first electrode automatically provides electrical contact through its elastic abutment against the first electrode pin upon insertion. This self-service mechanism eliminates the need for manual wire threading and welding operations, enabling automated assembly while ensuring reliable electrical connection.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual welding and threading processes are used, then electrical connection is achieved, but assembly process becomes tedious and difficult to automate

Engineering Contradiction:
Improveelectrical connectionVSAvoidautomated assembly capability
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The patent replaces manual welding and threading operations with a mechanical insertion system featuring a bayonet socket and elastic electrode. The first electrode pin is inserted directly into the bayonet socket, and the elastic connection end automatically establishes electrical contact, enabling complete automation of the assembly process.

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

Solution Approach 2:

The bayonet socket is pre-equipped with the first electrode having an elastic connection end before the assembly process begins. This preliminary preparation allows the first electrode pin to be simply inserted and automatically establish electrical contact through elastic abutment, eliminating the need for on-site welding and threading operations.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If wire threading and welding is used for connection, then electrical connection is established, but production time increases

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidproduction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces time-consuming wire threading and welding processes with a rapid mechanical insertion system. The first electrode pin is inserted into the bayonet socket in one operation, and the elastic connection end immediately establishes stable electrical contact through elastic abutment, dramatically reducing production time while maintaining connection stability.

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

Solution Approach 2:

The bayonet socket is pre-configured with the first electrode having an elastic connection end before assembly. This preliminary action allows the electrical connection to be established immediately upon insertion of the first electrode pin, eliminating the time required for wire threading and welding operations.

Inventive Principle:
Principle #10Preliminary action
