Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the head display is pulled by external force during falling in existing transmission technology, then the falling process continues, but this causes motor burnout or coil sticking

Engineering Contradiction:
Improveunattended operation capabilityVSAvoidmotor and coil protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-configuring a one-way bearing in the transmission mechanism that automatically prevents reverse rotation when external force is applied during falling. This preliminary mechanical design ensures that before any damage can occur, the one-way bearing has already blocked the harmful reverse motion, protecting the motor and coil from burnout or sticking while allowing unattended operation.

Inventive Principle:
Principle #10Preliminary action

2Extent of automation

If the head display connection cord is not retracted when device is powered off, then the cord remains extended, but this causes property damage in unattended operation environment

Engineering Contradiction:
Improveautomatic cord retractionVSAvoidproperty protection
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent implements self-service through an automatic cord retraction mechanism that uses a reel and spring system to automatically wind and store the connection cord when the device is powered off or not in use. This eliminates the need for manual cord management and prevents property damage by ensuring the cord is always properly stored, making the system suitable for unattended operation environments.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the VR controller uses Bluetooth wireless connection, then the connection is flexible, but data transmission is unstable due to environmental interference

Engineering Contradiction:
Improvewireless connection convenienceVSAvoiddata transmission stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary approach by using a wired connection (USB cable) between the VR controller and the main device, replacing the direct wireless Bluetooth connection. This intermediary physical connection serves as a more stable transmission medium that is not susceptible to environmental interference, while still maintaining ease of operation through a simple plug-and-play interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the VR handle uses battery power supply with rear cover opening, then the power supply is replaceable, but power interruption and data transmission failure occur due to insufficient power

Engineering Contradiction:
Improvepower supply flexibilityVSAvoidcontinuous power supply
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the power supply function by integrating a rechargeable battery directly into the VR handle with a built-in charging port. This combines the flexibility of replaceable power (through USB recharging) with the reliability of continuous power supply, eliminating the need to open the rear cover and ensuring uninterrupted power and data transmission during operation.

Inventive Principle:
Principle #5Merging (Combining)

5Ease of operation

If the main menu key is pressed to activate the VR handle, then the handle can be activated, but operation interruption or system crash occurs due to incorrect operation

Engineering Contradiction:
Improvehandle activationVSAvoidsystem stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies feedback by implementing a dual-key press mechanism for activating the main menu, requiring simultaneous or sequential pressing of two specific keys. This feedback-based activation method prevents accidental or incorrect single-key presses that could cause operation interruption or system crash, while still allowing easy activation through the defined key combination.

Inventive Principle:
Principle #23Feedback

6Ease of operation

If the VR handle employs wireless connection, then the connection is flexible, but the handle is easily lost causing property damage

Engineering Contradiction:
Improvewireless connection flexibilityVSAvoidanti-theft capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent inverts the connection approach by replacing wireless connection with a wired USB connection for the VR handle. This reversal eliminates the flexibility advantage of wireless but gains the anti-theft capability, as the physical cable connection prevents the handle from being easily lost or stolen, making it suitable for public and unattended operation environments.

Inventive Principle:
Principle #13The other way round (Inversion)

7Reliability

If someone is on duty to attend the VR devices, then the devices can be monitored, but operating cost increases and market launch becomes difficult

Engineering Contradiction:
Improvedevice monitoringVSAvoidoperational overhead
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service through automatic cord retraction, automatic device storage, and automated operation management features. These self-service capabilities eliminate the need for human attendants to monitor and manage the VR devices, reducing operating costs and simplifying deployment while maintaining reliable device monitoring and protection through automated systems.

Inventive Principle:
Principle #25Self-service

8Ease of operation

If the VR device cannot be automatically stored, then the device remains accessible, but device loss rate increases and operating cost increases

Engineering Contradiction:
Improvedevice accessibilityVSAvoiddevice security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements self-service through an automatic device storage mechanism that uses a reel and locking system to automatically retract and secure the VR handle and other components when not in use. This self-storing capability maintains device accessibility during operation while ensuring security during non-use periods, preventing device loss without requiring manual intervention.

Inventive Principle:
Principle #25Self-service
