Seat-Integrated MID Module for Multi-Function Public Transport Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional modules for public transport vehicles do not allow the integration of multiple electronic devices due to integration constraints such as size, cabling, and aesthetics, limiting the provision of enhanced passenger comfort.
Innovation Solution
The integration of Mechatronics Integrated Devices (MID) technology, utilizing methods like Laser Direct Structuring and plasma metallization, enables the incorporation of various electronic components, including a reading light, presence sensor, USB plug, and NFC antenna, within a single module that conforms to the seat's curvature for aesthetic integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional separate devices are used for each electronic function, then each device can be individually installed and maintained, but the number of cables and mounting points increases, compromising aesthetics and increasing complexity
Solution Approach 1:
The patent combines multiple electronic devices (reading light, presence sensor, USB plug, NFC antenna, seat reservation display) into a single integrated functional module that mounts to the seat in one location, eliminating the need for separate cables and mounting points for each device while maintaining all individual functions
Solution Approach 2:
The functional module serves as a universal platform that can provide multiple electronic functions simultaneously - illumination, sensing, power delivery, communication, and display - all within a single integrated unit that can be installed in one mounting location
2Adaptability or versatility
If multiple electronic devices are integrated in different parts, then each device can be independently accessed, but the overall integration level remains poor and space is wasted
Solution Approach 1:
The functional module employs a nested structure where multiple electronic devices and their components are integrated within a single compact housing, with each device nested within the same spatial envelope rather than requiring separate volumes, thereby reducing the overall module size while maintaining all functions
3Ease of manufacture
If traditional devices are used, then installation is straightforward with separate components, but aesthetic integration to the seat curvature is compromised
Solution Approach 1:
The functional module housing is designed with curved surfaces that follow and conform to the curvature of the seat, allowing aesthetic integration into the seat's contours while maintaining a single integrated structure that is installed as one unit, preserving both manufacturing simplicity and aesthetic quality
