Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional input devices or voice commands are used to control smart devices, then control functionality is achieved, but the system becomes cumbersome and inefficient, especially in noisy environments

Engineering Contradiction:
Improvecontrol convenienceVSAvoidinput method complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical input devices (remote controls, keyboards) and voice-based control systems with a neuromuscular sensing system that directly detects electrical signals from muscle contractions. This substitution eliminates the need for physical input devices and voice processing, providing a more direct and intuitive control method that works in noisy environments where voice commands fail.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces neuromuscular sensors as an intermediary between the user's intent and the smart device control system. These sensors detect electrical signals from muscle contractions and translate them into control commands, serving as a bridge that converts physiological signals into actionable instructions for smart devices without requiring traditional input methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If voice commands are used for controlling smart devices, then hands-free operation is achieved, but control becomes unreliable in noisy environments

Engineering Contradiction:
Improvehands-free controlVSAvoidcontrol accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces acoustic-based voice recognition with electrical signal-based neuromuscular sensing. By detecting the electrical signals generated during muscle contractions, the system provides hands-free control that is independent of acoustic conditions, ensuring reliable operation in noisy environments where voice commands become unreliable.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If current XR system control techniques are used, then interaction capability is achieved, but the control methods have significant flaws and are inefficient

Engineering Contradiction:
Improveinteraction capabilityVSAvoidinteraction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces traditional XR control methods (hand controllers, body tracking) with direct neuromuscular signal detection. This substitution provides more natural and intuitive interaction by capturing the user's intent at the source (muscle contraction) rather than interpreting external movements, significantly improving interaction efficiency and reducing latency in XR environments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If traditional remote control methods are used, then device control is achieved, but latency is high and real-time control is difficult

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces multi-step traditional remote control processes (signal transmission through multiple devices, processing delays) with direct neuromuscular signal detection and immediate translation to control commands. This direct pathway from muscle contraction to device control eliminates intermediate processing steps and significantly reduces latency, enabling real-time remote control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Computerized systems, methods, apparatuses, and computer-readable storage media are provided for generating a 3D map of an environment and/or for utilizing the 3D map to enable a user to control smart devices in the environment and/or to interact with a person in the environment. To generate the 3D map, perform the control, and/or interact with the person, a plurality of neuromuscular sensors may be worn by the user. The sensors may be arranged on a carrier worn by the user, and may be configured to sense neuromuscular signals from the user. A camera configured to capture information about the environment may be arranged on the carrier worn by the user. The sensors and the camera provide data to a computer processor coupled to a memory.
