Solution Overview

Problem

Existing headsets used in devices like optical and virtual reality systems face challenges in maintaining stable alignment with a subject's head during movement, leading to inaccurate readings and increased operation time due to the need for frequent restarts, while also causing discomfort and anxiety from restrictive restraints.

Innovation Solution

A dynamic headset apparatus with a head cradle and mount system that allows the device to move with the subject's head, maintaining alignment through a convex bottom surface and rotational paths, reducing restraint-induced anxiety and improving comfort and data quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the headset uses a fixed positioning system to maintain stable alignment with the subject's head, then measurement precision is improved, but the subject experiences discomfort and anxiety due to restrictive restraints

Engineering Contradiction:
Improvealignment accuracyVSAvoidsubject discomfort and anxiety
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies the dynamics principle by transitioning from a fixed, static positioning system to a dynamic system that allows controlled movement. The head cradle incorporates a mounting mechanism with degrees of freedom that enables the device to move with the subject's head while maintaining alignment, thereby reducing restrictive restraints and subject discomfort while preserving measurement precision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the positional parameters of the device relative to the subject's head by introducing a dynamic mounting system. This system allows the device to adjust its position and orientation in response to head movements, maintaining optimal alignment parameters without requiring rigid fixation, thus reducing subject discomfort while preserving measurement accuracy.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the headset allows subject movement to improve comfort, then subject comfort is improved, but alignment stability deteriorates leading to inaccurate readings

Engineering Contradiction:
Improvesubject comfortVSAvoidalignment accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements a dynamic positioning system where the device is mounted on the head cradle with controlled degrees of freedom. This allows the device to move naturally with the subject's head movements, maintaining alignment stability without requiring rigid restraint, thus improving subject comfort while preserving measurement precision.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the headset uses restrictive restraints to maintain stable alignment, then measurement precision is improved, but operation time increases due to subject resistance and restarts

Engineering Contradiction:
Improvealignment accuracyVSAvoidoperation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent employs a dynamic mounting system that accommodates subject movement rather than resisting it. This eliminates the need for frequent restarts caused by subject resistance to restrictive restraints, thereby reducing operation time while maintaining alignment precision through the device's ability to move with the subject's head.

Inventive Principle:
Principle #15Dynamics

4Stability of the object's composition

If the headset uses a fixed mounting system to maintain device stability, then device stability is improved, but adaptability to head movements deteriorates

Engineering Contradiction:
Improvedevice stabilityVSAvoidadaptability to head movements
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a fixed mounting system to a dynamic one that provides controlled stability. The device is mounted with degrees of freedom that allow it to adapt to head movements while maintaining stable alignment through the head cradle's geometry and mounting mechanism, thus achieving both device stability and adaptability to head movements.

Inventive Principle:
Principle #15Dynamics
