Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device changes operation mode based on a predetermined folding angle, then the device structure is simple and easy to manufacture, but the device cannot flexibly adapt to different application needs and user preferences

Engineering Contradiction:

Improveflexibility of operation modeVSAvoidcomplexity of mode switching mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the operation mode switching flexible and adaptive rather than fixed. The processor dynamically determines operation modes based on real-time folding angle detection, allowing the system to adapt to different applications and user preferences. This resolves the contradiction by enabling versatility through dynamic decision-making algorithms without adding complex mechanical switching mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of mode switching from fixed predetermined angles to dynamically adjustable ranges. By modifying the folding angle ranges used for mode determination based on application types and user preferences, the system achieves greater flexibility. This parameter change allows the same hardware to support multiple operation modes adaptively without increasing structural complexity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the electronic device uses a fixed folding angle range for mode switching, then the device operation is simple and reliable, but the device cannot provide customized experiences for different applications

Engineering Contradiction:

Improveapplication-specific mode customizationVSAvoidintuitiveness of mode recognition

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements feedback by continuously monitoring the folding angle through sensors and using this information to dynamically adjust operation modes. The system provides feedback to the user through intuitive mode recognition while adapting to different applications. This resolves the contradiction by maintaining ease of operation through automatic sensor-based detection while enabling application-specific customization through adaptive mode selection.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by pre-defining multiple operation mode ranges for different applications before runtime. When an application is launched, the system has already prepared appropriate folding angle ranges for that specific application type. This allows the device to provide customized experiences without requiring complex real-time calculations, maintaining ease of operation while achieving application-specific adaptation.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If the electronic device monitors folding angle continuously with high precision, then the mode switching accuracy is improved, but the energy consumption increases

Engineering Contradiction:

Improvefolding angle detection precisionVSAvoidenergy consumption of sensor

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action by monitoring the folding angle at specific intervals rather than continuously. The sensor detects folding angles periodically, and the processor determines mode transitions based on these periodic measurements. This resolves the contradiction by maintaining sufficient measurement precision for accurate mode switching while significantly reducing energy consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent uses partial action by monitoring folding angles only when necessary for mode transition decisions. Rather than continuously measuring with high precision, the system performs measurements at critical moments when mode switching may occur. This partial monitoring approach maintains adequate precision for operational needs while minimizing energy consumption by avoiding excessive measurement activity.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A foldable electronic device may include a flexible display, a sensor circuit, a processor and a memory. The foldable electronic device may be such that it: executes an application on the basis of a first mode, if a folding angle is within a first range; identifies a folding angle via the sensor circuit according to a first cycle while the application is executed in the first mode; if the identified folding angle is not within the first range, switches the execution mode of the application from the first mode to a second mode; and changes the range for switching the execution mode of the application from the first range to the second range based on at least one of the identified folding angles.
