Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cable is used to electrically connect the conductive core and the circuit board, then electrical connection is achieved, but the mounting steps become complex and connection reliability problems occur

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmounting steps complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the cable from the connection system. Instead of using a cable to connect the conductive core to the circuit board, the conductive core is directly soldered to the circuit board, eliminating the intermediate cable component and simplifying the mounting process while improving connection reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the conductive core directly with the circuit board through soldering, combining two previously separate connection elements (conductive core and circuit board) into a single integrated electrical connection, thereby eliminating the need for additional cables and reducing mounting complexity

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If traditional connector mounting methods are used, then connectors can be installed, but the assembly process requires much effort and takes significant time

Engineering Contradiction:
Improveassembly easeVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-assembling the conductive core with the housing and preparing the solder leg for direct soldering to the circuit board before final installation. This pre-preparation reduces the effort and time required during the actual assembly process, as the connector is ready for quick attachment to the panel and circuit board

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the connector into distinct functional parts (housing, conductive core, solder leg, fastening structure) that can be independently manufactured and then quickly assembled. This segmentation allows for standardized production and simplifies the final assembly process, reducing both effort and time requirements

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If connectors are mounted on a panel, then electrical connections are established, but the layout density is reduced due to space requirements for cables and mounting operations

Engineering Contradiction:
Improvelayout densityVSAvoidoperation space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent removes the cable from the connector assembly, eliminating the space that would be required for cable routing, connection, and management. This extraction allows connectors to be mounted closer together on the panel, increasing layout density without requiring additional operation space for cable handling

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the electrical connection function directly into the connector housing through the integrated conductive core and solder leg, eliminating the need for separate cable connections. This consolidation reduces the space required for mounting operations and allows for more compact connector arrangements on the panel

Inventive Principle:
Principle #5Merging (Combining)
