Aircraft Information Transmission System Using Vibration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face a high workload due to the need to rapidly process and react to various changing information inputs while operating an aircraft, which can lead to increased stress and decreased efficiency in decision-making.
Innovation Solution
An information transmission system that determines relevant information for pilots using a combination of visual, auditory, and vibrational outputs, categorizing messages as emergency, caution, or report to prioritize and simplify information delivery, utilizing vibrating devices strategically placed within the cockpit to enhance alertness and focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple information channels (visual, auditory) are used to transmit information to the pilot, then the completeness and priority of information transmission is improved, but the complexity of the transmission system increases
Solution Approach 1:
The information transmission system is segmented into multiple independent channels (visual display, auditory output, vibration feedback) that can operate simultaneously. Each channel handles specific types of information or priority levels, allowing comprehensive information delivery without requiring a single complex integrated system.
Solution Approach 2:
The control unit serves multiple functions by managing both visual display output and auditory/vibration output channels. This multi-functional approach allows a single control unit to coordinate multiple transmission channels, reducing overall system complexity while maintaining information completeness.
2Ease of operation
If vibration feedback is added to the information transmission system, then pilot alertness and information perception are improved, but the device complexity and number of components increase
Solution Approach 1:
Vibration feedback is applied locally at specific contact points between the pilot and aircraft controls (control stick, throttle lever, rudder pedal) rather than throughout the entire cockpit. This targeted approach enhances information perception where the pilot naturally interacts with the aircraft, minimizing the number of vibrating devices needed.
Solution Approach 2:
The control stick, throttle lever, and rudder pedal serve as intermediary elements that transmit vibration feedback from the vibrating devices to the pilot's hands and feet. These existing control surfaces act as natural mediators, eliminating the need for separate feedback mechanisms and reducing overall system complexity.
3Reliability
If information is transmitted through multiple modalities (visual, auditory, vibration), then the reliability of information delivery is improved, but the energy consumption increases
Solution Approach 1:
The system uses periodic or intermittent vibration feedback rather than continuous operation. Vibration is activated only when specific information needs to be conveyed to the pilot, and the duration/intensity can be varied based on information priority. This periodic activation maintains reliable information delivery while significantly reducing energy consumption compared to continuous multi-modal transmission.

AI summary
According to one implementation, an information transmission system includes: a transmission information determination part, an output device; and at least one vibrating device. The transmission information determination part is adapted to determine transmission information to a pilot of an aircraft. The output device is adapted to transmit the transmission information to the pilot by a visual representation, voice, sound or a light. The at least one vibrating device is adapted to propagate a vibration to the pilot when the transmission information is transmitted to the pilot.
