Solution Overview

Problem

Passengers experience discomfort and health risks during long flights due to inadequate seating comfort, which is exacerbated by the need for lightweight and compact aircraft seats that compromise on ergonomics and safety, while existing solutions do not effectively enhance travel comfort.

Innovation Solution

A seating system for passenger aircraft equipped with a sensor device that detects seat load and posture, providing real-time feedback to passengers via a smartphone app to adjust their sitting position for improved comfort and health, while also being lightweight and easily retrofittable to existing seats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If lightweight and compact seats are installed to reduce aircraft weight and cost, then weight and cost efficiency are improved, but seating comfort and ergonomics deteriorate

Engineering Contradiction:
Improveaircraft weightVSAvoidseating comfort
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism using sensors to detect passenger seating posture and provides real-time feedback through a mobile device interface. The system monitors seat load distribution, backrest angle, and sitting position, then guides passengers to adopt healthier postures through visual feedback displayed on their personal devices, thereby improving comfort without adding physical bulk to the seats

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables passengers to self-monitor and self-adjust their seating posture based on real-time feedback from the sensor device. Passengers receive personalized guidance on how to position themselves optimally, allowing them to take active control of their own comfort and health during the flight without requiring additional physical resources from the aircraft

Inventive Principle:
Principle #25Self-service

2Ease of operation

If passengers sit in unchanged positions for extended periods to maintain comfort, then ease of operation is maintained, but health risks increase

Engineering Contradiction:
Improveseating comfortVSAvoidhealth risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors passenger seating posture through sensors and provides real-time feedback via mobile devices. When unhealthy postures are detected or maintained for extended periods, the system alerts passengers and guides them to adjust their position, preventing health risks associated with prolonged static sitting while maintaining overall comfort

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent implements periodic monitoring and feedback cycles where the sensor device continuously assesses seating posture and provides periodic guidance to passengers. This creates a rhythm of posture assessment and adjustment that prevents passengers from maintaining harmful static positions for too long while still allowing comfortable sitting during appropriate intervals

Inventive Principle:
Principle #19Periodic action

3Object-affected harmful factors

If sensor devices are added to detect seating position and provide feedback, then health and comfort are improved, but device complexity increases

Engineering Contradiction:
Improvehealth risksVSAvoidseating system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent utilizes smartphones and mobile devices that passengers already possess, leveraging their existing processing power, display capabilities, and connectivity. The sensor device communicates with these universal personal devices rather than requiring dedicated complex output hardware in each seat, thereby reducing overall system complexity while maintaining full functionality

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a wireless communication interface as an intermediary between the simple sensor device and the passenger's smartphone. This intermediary layer uses standard wireless protocols to transmit posture data and receive control signals, avoiding the need for complex wired connections or integrated display systems in the seats themselves

Inventive Principle:
Principle #24Intermediary (Mediator)
