Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired connections are used to ensure reliable communication, then connection stability is improved, but device portability and ease of operation deteriorate

Engineering Contradiction:

Improveconnection stabilityVSAvoiddevice portability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication systems. The HMD incorporates wireless transceivers that enable communication with external devices without physical cables, substituting the mechanical connection system with an electromagnetic field-based system that provides both portability and reliable communication.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If onboard processors are integrated to enhance functionality, then interactive capabilities are improved, but device weight and complexity increase

Engineering Contradiction:

Improveinteractive capabilitiesVSAvoiddevice weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent divides the processing functionality into segments: the HMD contains an onboard processor for basic interactive operations and sensor data processing, while more complex computational tasks are offloaded to external devices or cloud services. This segmentation allows the HMD to gain interactive capabilities without bearing the full weight of high-performance processing hardware.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The onboard processor is designed to perform multiple functions including processing data from integrated sensors (cameras, microphones, motion detectors), rendering mixed reality content, managing wireless communications, and coordinating with external devices. This multi-functionality reduces the need for separate dedicated hardware components, thereby limiting weight increase while enhancing interactive capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple sensors and cameras are added for mixed reality, then functionality is improved, but device complexity and power consumption increase

Engineering Contradiction:

Improvemixed reality functionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sensing functions into integrated sensor modules. Cameras, microphones, motion detectors, and other sensors are merged into unified assemblies that share common processing circuits and data buses. This merging reduces the overall complexity of wiring, mounting, and data management while maintaining full mixed reality functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces intermediary processing layers that manage data from multiple sensors. A sensor fusion processor or firmware layer acts as an intermediary, aggregating data from cameras, microphones, and motion detectors, then presenting processed information to higher-level applications. This intermediary approach simplifies the complexity by providing a standardized interface rather than requiring direct integration of all sensor components.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If wireless transceivers are integrated for wireless connectivity, then ease of operation is improved, but energy consumption increases

Engineering Contradiction:

Improvewireless connectivityVSAvoidenergy consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The wireless transceiver operates using periodic action principles, entering low-power sleep modes between communication events and activating only when data transmission or reception is required. The system uses duty cycling to maintain wireless connectivity capability while minimizing energy consumption during idle periods, allowing the HMD to achieve wireless ease of operation without excessive power drain.

Inventive Principle:

Principle #19Periodic action

AI summary

Images are overlaid using a personal viewing device, such as a head mounted display. The personal viewing device includes a mount, an electronic display, a lens, and an electronic circuit. The electronic display, lens, and electronic circuit are physically attached to the mount. The electronic display and lens are positioned by the mount so that an eye views the electronic display through the lens. The electronic circuit overlays a first image with a second image to produce an overlaid image. The electronic circuit then displays the overlaid image on the electronic display. The electronic circuit can include an image generating device. The image generating device can generate the first image and/or the second image. The image generating device can be a video player or a processor. The personal viewing device can further include a wireless transceiver attached to the mount.
