Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the same power supply program is used for multiple groups of digital power control chips, then manufacturing cost is reduced, but performance is sacrificed due to differing PCB designs and component combinations

Engineering Contradiction:
Improvemanufacturing costVSAvoidperformance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The power supply program is segmented into multiple groups, each optimized for specific PCB designs and component combinations. The system divides the single program into multiple specialized programs stored in the digital power control chip, allowing different groups of chips to use different optimized programs while sharing the same physical hardware platform.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects the appropriate power supply program group based on the resistor configuration detected during initialization. The digital power control chip can adaptively switch between different program groups to match the specific PCB design and component combination, enabling the same hardware to optimize performance for multiple different configurations.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the power supply program is burned into the digital power control chip during production, then device complexity is reduced, but adaptability is limited requiring repeated testing and debugging

Engineering Contradiction:
Improvedevice complexityVSAvoidadaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The digital power control chip is designed with multi-functionality to support multiple power supply program groups within a single device. This universal design allows the same chip model to be used across different PCB designs and component combinations by selecting the appropriate program group, eliminating the need for different chip models for different applications.

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

Solution Approach 2:

Multiple power supply program groups are pre-burned into the digital power control chip during manufacturing, preparing the device in advance for different PCB designs and component combinations. This preliminary action eliminates the need for repeated testing and debugging during production, as the appropriate program is already available in the chip.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If different performance parameters are used for different groups of power supplies, then performance is optimized, but device complexity increases requiring multiple program versions

Engineering Contradiction:
ImproveperformanceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple power supply program groups with different performance parameters are merged into a single digital power control chip. The chip integrates multiple optimized programs that can be selectively activated based on the resistor configuration, consolidating what would otherwise require multiple different chip models into one universal device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The resistor configuration serves as an intermediary that mediates between the hardware design and the software program selection. The resistor value detected during initialization determines which power supply program group is activated, providing a simple hardware-based mechanism for selecting among multiple performance configurations without increasing overall system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
