Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-quality VR experience is provided, then VR quality is improved, but power consumption increases

Engineering Contradiction:
ImproveVR qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the working state of the mobile terminal changeable between active and standby modes based on real-time sensor detection. The system dynamically adjusts power consumption by switching states according to user presence detection, resolving the contradiction between maintaining VR quality and reducing power usage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses self-service by automatically detecting user presence through sensors (optical, pressure, position) and autonomously switching between active and standby states without manual intervention. This resolves the contradiction by enabling the system to self-regulate power consumption while maintaining VR functionality when needed.

Inventive Principle:
Principle #25Self-service

2Reliability

If the mobile terminal remains in active state, then VR functionality is maintained, but usage time decreases

Engineering Contradiction:
ImproveVR functionalityVSAvoidusage time
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent applies periodic action by using sensors to periodically detect user presence and switching the terminal state accordingly. The system alternates between active and standby states based on detection cycles, extending usage time while ensuring VR functionality is available when users are present.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system applies preliminary action by detecting user absence in advance through sensors and proactively switching to standby mode before battery depletion occurs. This extends usage time by preventing unnecessary power consumption while ensuring VR functionality is restored quickly when users return.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If sensors are used to detect inactive states, then power saving is improved, but device complexity increases

Engineering Contradiction:
Improvepower savingVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the detection function into multiple specialized sensors (optical sensor for light detection, pressure sensor for contact detection, position sensor for movement detection). Each sensor handles a specific detection task, improving power saving through targeted detection while managing complexity through functional segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies universality by using a processor that handles multiple functions: sensing data acquisition, state determination, and communication control. This multi-functional approach improves power saving through centralized intelligence while managing overall device complexity by consolidating control functions.

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

AI summary

A method and a device for controlling a working state belong to the field of internet technologies. The method includes: when it is determined that a current state of a playback device is in an inactive state, by a sensor, detecting (302) whether a mobile terminal, which has established a communication link with the playback device, is in a working state; and when the mobile terminal is in the working state, sending (304) to the mobile terminal an instruction for instructing the mobile terminal to shift its state into a standby state.
