Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If 5G antenna functions are implemented in electronic devices with telescopic flexible screens, then data rate and system capacity are improved, but device complexity and implementation difficulty increase

Engineering Contradiction:
Improvedata rateVSAvoidantenna complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic antenna configuration where the antenna system automatically adjusts its operational mode based on the device's physical state. When the device is in extended status, the antenna component activates 5G communication functions with full radiating elements. When contracted, the system switches to a simplified mode or deactivates 5G functions. This dynamic adaptation resolves the contradiction by enabling high data rates only when the device structure supports the required antenna complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the antenna system based on device status. The main board receives status signals and transmits control signals to the antenna component to switch between different antenna schemes. This parameter change approach allows the system to maintain 5G capability when needed while simplifying the antenna configuration when the device is contracted, thereby managing complexity while preserving productivity when required.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If antenna component is configured to support both contracted and extended statuses, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveantenna adaptabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The antenna component is designed with multi-functionality to operate in different configurations. The same antenna component can form different antenna schemes by selectively activating radiating elements based on device status. This universal design allows the antenna system to adapt to both contracted and extended statuses without requiring separate antenna systems, thereby improving adaptability while controlling complexity through shared hardware resources.

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

Solution Approach 2:

The system dynamically switches between different antenna configurations based on real-time device status. The main board monitors whether the device is in contracted or extended status and automatically transmits control signals to adjust the antenna component's configuration. This dynamic switching mechanism enables the antenna system to adapt to varying structural conditions without manual intervention, resolving the contradiction between adaptability and complexity through automated dynamic reconfiguration.

Inventive Principle:
Principle #15Dynamics

3Reliability

If radiating elements are adjusted based on device status, then antenna performance is improved, but control complexity increases

Engineering Contradiction:
Improveantenna performanceVSAvoidcontrol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements a feedback control mechanism where the main board receives status information about the device's physical state (contracted or extended) and automatically adjusts the antenna component's configuration accordingly. This feedback loop ensures that the antenna performance is optimized for the current device status without requiring complex manual control. The main board processes the status signal and generates appropriate control signals to activate the correct antenna scheme, thereby improving reliability while managing control complexity through automated feedback-based control.

Inventive Principle:
Principle #23Feedback

AI summary

Provided is an electronic device, including: a device body and a flexible screen and an antenna component assembled on the device body. A bent display status of the flexible screen matches with a contracted status of the device body, and an unfolded display status of the flexible screen matches with an extended status of the device body, so that the electronic device can be used in contraction and extension statuses. Furthermore, the main board of the device body can control at least one radiating element of the antenna component to form a first antenna scheme when the device body is in the extended status, and form a second antenna scheme when the device body is in the contracted status.
