Vehicle Sliding Module With Magnetic Locking for Collision Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding devices for vehicles malfunction during collisions, causing additional injuries due to the movement of seats or tables, as they are not effectively secured to the vehicle body.
Innovation Solution
A sliding device with a magnetic module that can be fixed or unfixed from the floor based on a change in magnetic circuit, utilizing a first magnetic body, a second magnetic body, and a base plate, along with catching and fastening portions, to prevent movement during external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic module is used to fix the movable member to the floor, then the reliability during collision is improved, but the device complexity increases due to additional magnetic components and control mechanisms
Solution Approach 1:
The patent replaces traditional mechanical locking mechanisms with a magnetic field-based fastening system. The magnetic module uses magnetic attraction forces to secure the movable member to the floor, eliminating complex mechanical linkages, pins, and locking mechanisms while achieving reliable fixation during collision.
Solution Approach 2:
The patent utilizes changes in magnetic field parameters (strength, direction, or presence) to control the fastening state. By adjusting magnetic field parameters, the system can transition between secured and released states without mechanical movement of locking components, simplifying the overall device structure while maintaining reliability.
2Reliability
If catching portions are provided on the floor spaced along the movement route, then the fastening reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent divides the fastening function into multiple discrete catching portions spaced along the movement route of the movable member. Each catching portion acts as an independent fastening point, ensuring that if one catching portion fails or is misaligned, others can still provide secure fastening, thereby improving overall reliability.
Solution Approach 2:
The catching portions are pre-positioned on the floor at specific locations along the movement route. This preliminary arrangement ensures that when the movable member moves into position, the fastening components can automatically engage with the pre-placed catching portions without requiring active positioning or adjustment during operation.
3Ease of operation
If the magnetic module is designed to slide freely on the floor, then the ease of operation is improved, but the stability during collision deteriorates
Solution Approach 1:
The patent creates a dynamic system where the movable member can freely slide during normal operation but automatically transitions to a stable fixed state when collision is detected or when reaching predetermined positions. The magnetic fastening mechanism engages only when needed, providing both ease of movement and collision stability.
Solution Approach 2:
The magnetic module is pre-configured to provide counteracting magnetic attraction forces that prevent unwanted movement during collision. This preliminary anti-action mechanism is always active but only becomes effective at restraining movement when collision forces are applied, allowing free sliding during normal use while providing stability when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic module securely fixes the seat or table to the floor, preventing secondary injuries by ensuring it remains stationary during vehicle collisions, even under sudden external impacts.
Implementation Method 1
a magnetic module configured to slide on a floor of the vehicle and be fixed to the floor by a magnetic force or unfixed from the floor in accordance with a change in magnetic circuit due to a rotation of a first magnetic body provided in the magnetic module
Implementation Method 2
at least a fastening portion provided on the magnetic module and configured to be pressed downward by a first elastic body
Implementation Method 3
a second elastic body configured to press the fastening portion and the magnetic module upward to move the fastening portion and the magnetic module upward in a state in which the second magnetic body is unfixed from the floor
