Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If components are connected through the motherboard, then the device structure is simple, but the information transmission efficiency and power-supply efficiency are insufficient

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidinformation transmission efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent divides the connection path into two separate paths: one through the motherboard for power supply and one through the package substrate for information transmission. This segmentation allows each path to be optimized independently, with the package substrate providing high-speed data transmission and the motherboard providing stable power delivery.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package substrate acts as an intermediary component between the accelerator chip and the motherboard. It provides dedicated conductor patterns for both power supply and signal transmission, mediating the connection requirements and enabling efficient communication while maintaining structural simplicity through the motherboard interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If components are connected through the motherboard, then the device structure is simple, but the power-supply efficiency is insufficient

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidpower-supply efficiency
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent separates power supply connections from signal connections, with power supplied through the motherboard and signals transmitted through the package substrate. This segmentation reduces electrical interference and allows for optimized power delivery paths with appropriate impedance control and power management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The package substrate serves as an intermediary that receives power from the motherboard through dedicated power pads and distributes it to the accelerator chip through optimized power delivery networks, improving power-supply efficiency while maintaining the simple motherboard connection structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If components are connected only through the package substrate, then the information transmission efficiency improves, but the device complexity increases

Engineering Contradiction:
Improveinformation transmission efficiencyVSAvoidconnection structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the power supply function and signal transmission function into a single package substrate component. The substrate simultaneously provides power delivery networks and signal transmission paths, consolidating multiple functions into one element and reducing overall system complexity despite the enhanced connection capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The package substrate is designed with multi-functionality, serving both as a power distribution network and as a signal transmission medium. This universal component handles both electrical power delivery and high-speed data communication, eliminating the need for separate connection structures and reducing overall device complexity.

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

AI summary

An electronic circuit module is an electronic circuit module mounted on a motherboard having a power supply source. The electronic circuit module includes a photoelectric conversion unit which performs conversion between an optical signal and an electric signal, a processor unit which performs computational processing by using an electric signal, a power conversion unit which converts power from the power supply source and which supplies power to the photoelectric conversion unit and the processor unit, and a package substrate on which the photoelectric conversion unit, the processor unit, and the power conversion unit are mounted. The photoelectric conversion unit, the processor unit, and the power conversion unit are connected only through a conductor pattern formed on/in the package substrate.
