Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soldering is used for electrical connection, then electrical connection stability is improved, but assembly complexity and manufacturing time increase

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the thermal-mechanical soldering process with a pure mechanical insertion system. The spring plates provide electrical connection through elastic contact force when connectors are plugged together, eliminating the need for soldering operations while maintaining connection reliability through the resilient nature of the spring plates that compensate for assembly tolerances.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring plates are designed to automatically establish electrical contact through their elastic deformation when the male and female connectors are inserted. The resilient structure self-adjusts to ensure reliable contact without requiring external soldering processes, making the connection process self-completing and eliminating complex assembly steps.

Inventive Principle:

Principle #25Self-service

2Reliability

If soldering is used for electrical connection, then electrical connection stability is improved, but manufacturing efficiency decreases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the time-consuming soldering process with instantaneous mechanical insertion. The spring plates establish electrical connection immediately upon plugging, eliminating the heating, melting, and cooling cycles required for soldering, thereby dramatically improving manufacturing efficiency while maintaining connection stability through elastic contact.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring plates are pre-formed with elastic properties during manufacturing, so that when the connectors are inserted, the electrical connection is automatically established without requiring any additional processing steps. This preliminary preparation of the resilient structure enables instant connection and eliminates post-assembly soldering operations.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If soldering is used for electrical connection, then electrical connection stability is improved, but defect rate increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent eliminates soldering-related defects by replacing the thermal process with mechanical insertion. Common soldering defects such as cold joints, solder bridges, and insufficient wetting are completely avoided because no molten metal is involved. The spring plates provide reliable connection through elastic contact that is insensitive to minor variations in assembly conditions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring plates are designed as simple, replaceable components that can be easily manufactured and replaced if needed. Their simple elastic structure reduces manufacturing complexity compared to soldering processes, and any defects can be addressed by replacing the spring plate rather than re-soldering, significantly reducing overall defect rates.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A male-female mutually-pluggable connector includes first and second plastic cores and first and second metal spring plates. The first and second metal spring plates are each formed, on one end portion thereof, with plugging spring plates, and are also formed, on an opposite end thereof, with a wire insertion spring plate having a curved part. At least one of first and second metal spring plates is formed, in the one end portion thereof, with a slot and the slot has an opening having opposite sides that are raised and protruding to each other to form the plugging spring plates. The first and second metal spring plates are fixed in the first and second plastic cores, respectively. The plugging spring plates of the first and second metal spring plates are inter-plugged with each other to form a crossing form.
