Innovation Solution

A hybrid power connector design with power inputs and outputs on opposite sides, utilizing copper sheets with screw-fixing holes, and signal inputs connected to signal outputs through the circuit board trace, optimizing material use and assembly by guiding docking pins for easy connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If large-area copper bars are used on the circuit board for heat dissipation, then heat dissipation capability is improved, but material cost and manufacturing complexity increase

Engineering Contradiction:
Improveheat dissipation capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent extracts the high-current power transmission function from the circuit board and relocates it to a dedicated connector with separate power terminals. This removes the burden of handling large currents and associated heat dissipation requirements from the circuit board, eliminating the need for large-area copper bars and complex multi-layer board designs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The connector is segmented into distinct power transmission components and signal transmission components. Power inputs and power outputs are separated and dedicated to specific terminals, allowing independent optimization of power handling capabilities without affecting signal integrity or requiring complex integrated solutions.

Inventive Principle:
Principle #1Segmentation

2Power

If the system output current is increased, then power supply capability is improved, but space requirement and manufacturing complexity increase

Engineering Contradiction:
Improvepower supply capabilityVSAvoidspace requirement
Core Design Contradiction:
PowerVSArea of stationary object

Solution Approach 1:

The connector utilizes three-dimensional spatial arrangement of terminals within the housing to accommodate high-current power transmission capabilities. By arranging power inputs and outputs in specific spatial configurations and using vertical stacking of connection layers, the design achieves high power capability without proportionally increasing the footprint area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If signal pins and power outputs are located at the rear side of the connector, then connection is simplified, but space utilization and assembling efficiency worsen

Engineering Contradiction:
Improveconnection simplicityVSAvoidassembling efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The connector merges signal inputs and power inputs into a unified front-side interface, while power outputs are positioned at the rear. This integrated arrangement allows simultaneous connection of both signal and power lines through a single docking action, eliminating the need for separate assembly operations and improving overall assembling efficiency.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If additional wire is assembled on the sheet metal for grounding, then grounding capability is improved, but material cost increases

Engineering Contradiction:
Improvegrounding capabilityVSAvoidmaterial cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The connector housing and terminal structure serve multiple functions simultaneously: they provide mechanical support, electrical insulation, and integrated grounding paths. The housing itself is designed to function as a grounding element, eliminating the need for separate grounding wires and reducing material requirements while maintaining reliable grounding capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
