Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional force measurement systems are used, then measurement functionality is provided, but the system occupies considerable floor space and cannot immerse subjects in virtual reality environments

Engineering Contradiction:

Improvevirtual reality immersion capabilityVSAvoidfloor space occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines force measurement functionality with virtual reality display components into an integrated head-mounted device. The force measurement assembly is merged with visual display elements, allowing the system to provide both measurement and immersive VR capabilities in a compact form factor that occupies minimal floor space while maintaining full measurement functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The head-mounted device serves multiple functions simultaneously: it acts as a force measurement instrument, a virtual reality display device, and an interactive interface for subjects. This multi-functionality eliminates the need for separate conventional force measurement systems and VR equipment, significantly reducing the overall space requirement while enhancing adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If conventional force measurement systems are used, then force quantification is achieved, but the system is cumbersome and difficult to accommodate in limited spaces

Engineering Contradiction:

Improveforce quantification accuracyVSAvoidsystem compactness

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The force measurement assembly is nested within the head-mounted device structure, with sensors and measurement components integrated into the wearable framework. This nesting approach maintains precise force measurement capabilities while consolidating multiple components into a compact configuration that is easy to accommodate in limited spaces.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces traditional bulky mechanical force measurement systems with integrated sensor-based measurement approaches within the head-mounted device. This substitution maintains measurement precision while dramatically reducing device complexity and physical footprint, making the system suitable for spaces with limited room.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If conventional force measurement systems are used, then measurement data is collected, but the system cannot effectively simulate real-life scenarios through virtual reality

Engineering Contradiction:

Improvereal-life scenario simulationVSAvoidsubject immersion experience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The head-mounted visual display device acts as an intermediary between the force measurement system and the subject, delivering virtual reality content that simulates real-life scenarios. This intermediary component enhances the subject's immersion experience by overlaying virtual environmental cues with physical feedback from the force measurement sensors, creating a more effective simulation of real-world conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback loops where force measurement data from the head-mounted device is processed and used to dynamically adjust virtual reality scenario parameters. This feedback mechanism enhances adaptability by allowing the system to respond to subject actions in real-time, creating more authentic real-life scenario simulations while maintaining ease of operation through intuitive interactive interfaces.

Inventive Principle:

Principle #23Feedback
