Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional passenger seat systems in airplanes make it difficult to determine whether the seat is reclined or the electronic device is turned, as both can change angles independently, complicating safety protocols during takeoff and landing.
Innovation Solution
An electronic device mounted on a seat that can turn around a first axis and is adjustable around a second axis, equipped with an acceleration sensor and controller to differentiate between seat and device movements based on temporal changes in acceleration information, and an information processing apparatus connected to multiple seats to determine seat and vehicle inclinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both the seat and the electronic device can change angles independently, then comfort and versatility are improved, but it becomes difficult to identify whether the seat is reclined or the device is turned
Solution Approach 1:
The system segments the detection of angle changes by distinguishing between seat angle changes and device angle changes through separate detection mechanisms. The acceleration sensor detects overall motion, while the controller analyzes temporal patterns to separate seat movement from device movement, enabling independent state identification for both components.
Solution Approach 2:
The controller continuously monitors acceleration information and provides feedback about the current state of the seat and device. By analyzing temporal changes in acceleration data, the system maintains accurate knowledge of whether the seat is reclined or the device is turned, even as both can move independently.
2Ease of operation
If the seat is made turnable around a first axis and the electronic device turnable around a second axis, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The acceleration sensor serves multiple functions: it detects seat angle changes, device angle changes, and vehicle motion. The controller processes this single sensor's data to determine the state of both the seat and the electronic device, reducing the need for multiple separate sensors and simplifying the overall system architecture.
Solution Approach 2:
The controller acts as an intermediary that processes acceleration information and translates it into meaningful state information about the seat and device. By using temporal change analysis as an intermediary method, the system can distinguish between different types of movements without requiring complex mechanical indicators or additional sensors.
