Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively address vertigo, motion sickness, and spatial disorientation in motion-provocative environments, leading to compromised human performance and loss of control, particularly in aviation, space travel, and other transportation modes.
Innovation Solution
The development of a system that integrates inertial sensors and a logic dongle with a helmet-mounted display, providing real-time visual cues and symbology to align vestibular and visual inputs, reducing sensory mismatch and enhancing user orientation through a combination of sensors and avionics subsystems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual cues and symbology are provided to align vestibular and visual inputs, then spatial orientation is improved, but device complexity increases
Solution Approach 1:
The system divides the complex task of spatial orientation into separate functional modules: inertial sensors detect motion, logic circuitry processes the sensor data, and display subsystems present visual cues. This segmentation allows each component to be optimized independently while working together to solve the overall problem of spatial disorientation.
Solution Approach 2:
The patent introduces an intermediary processing system (logic circuitry) that mediates between the vestibular sensors and visual display outputs. This intermediary translates sensor data into appropriate visual symbology and cues, creating a bridge between the user's internal sense of motion and the external visual information presented to them.
2Object-affected harmful factors
If inertial sensors and visual displays are integrated, then motion sickness is reduced, but ease of operation decreases
Solution Approach 1:
The system operates autonomously by automatically detecting user motion through inertial sensors, processing this data through logic circuitry, and generating appropriate visual cues without requiring manual input from the user. The system serves itself by continuously monitoring and adjusting visual feedback based on detected motion parameters.
Solution Approach 2:
The system performs preliminary processing of motion data through logic circuitry before presenting visual cues to the user. By pre-processing sensor signals and determining the appropriate visual symbology in advance, the system prepares corrective visual information that can be immediately displayed to counteract motion sickness symptoms.
3Productivity
If real-time visual cues are provided to enhance orientation, then human performance is improved, but use of energy increases
Solution Approach 1:
The system updates visual cues at periodic intervals based on detected motion changes rather than continuously, reducing energy consumption while maintaining effective spatial orientation. The inertial sensors sample motion parameters at specific rates, and visual displays refresh accordingly, providing sufficient feedback without wasteful continuous operation.
Solution Approach 2:
The system dynamically adjusts the provision of visual cues based on actual motion conditions detected by the sensors. Visual symbology is enhanced or reduced in intensity and frequency according to the level of detected motion and the user's apparent need for orientation assistance, optimizing energy use while maintaining performance benefits.
