Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an adapter apparatus with protocol conversion capability is introduced, then compatibility between DC power sources and load equipment is improved, but device complexity increases

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter apparatus serves as an intermediary device between the DC power source and load equipment. It contains a control circuit that converts communication protocols, allowing devices with different protocols to communicate through the adapter. The adapter translates data between first protocol (from power source) and second protocol (to load equipment), enabling compatibility without requiring changes to the original devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter apparatus is designed to support multiple communication protocols simultaneously. The control circuit can handle both first protocol communication with DC power sources and second protocol communication with load equipment. This multi-functional capability allows a single adapter design to work with various types of devices using different protocols, enhancing versatility.

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

2Adaptability or versatility

If protocol conversion is implemented through a control circuit, then communication between different devices is enabled, but manufacturing complexity increases

Engineering Contradiction:
Improvecommunication compatibilityVSAvoidcircuit integration
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The control circuit integrates multiple protocol conversion functions into a single integrated component. Rather than using separate conversion circuits for each protocol, the design merges the conversion logic into one unified control circuit that can handle both first and second protocols. This reduces the number of discrete components and simplifies the manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control circuit is designed to dynamically change its operational parameters based on the detected protocol type. When receiving data in the first protocol, it applies specific conversion parameters; when communicating in the second protocol, it uses different parameters. This parameter-based approach allows a single hardware design to handle multiple protocols without requiring physical reconfiguration.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If power regulation is added to the adapter, then power transmission efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvepower transmission efficiencyVSAvoidpower control circuitry
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The adapter performs preliminary power regulation before transmitting power to the load equipment. The control circuit receives power from the DC power source, regulates it to the appropriate voltage and current levels required by the load, and then transmits the regulated power. This preliminary action ensures efficient power transmission and prevents power-related issues at the load end.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adapter incorporates feedback mechanisms where the control circuit monitors the power transmission status and load requirements. Based on this feedback, the control circuit dynamically adjusts the power regulation parameters to optimize transmission efficiency. The enable terminal can activate or deactivate power transmission based on communication status, ensuring power is only transmitted when needed and under appropriate conditions.

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure relates to an adapter apparatus, a battery apparatus and an electronic device system. The adapter apparatus comprises: a power transmission line, configured to be coupled between a DC power source and load equipment; and a control circuit apparatus, configured to communicate with the DC power source via a first group of communication ports according to a first communication protocol, and to communicate with the load equipment via a second group of communication ports according to a second communication protocol, the first communication protocol being different from the second communication protocol. The transmitted data is used to regulate the power supply, which allows a DC power source such as a battery to power the load equipment at a desired power level. In addition, when the control circuit has multiple communication protocols to choose from, the adapter apparatus can adapt multiple types of DC power supplies with different communication protocols to the load equipment, and can also adapt multiple types of load equipment with different communication protocols to the DC power source.
