Vehicle Seat Switching Element for Simultaneous Lock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats for commercial vehicles require multiple actuating elements to manage the locking and unlocking of rotating and horizontal spring mechanisms, which is cumbersome and inefficient, especially during transitions between different terrains like farmland and roads.
Innovation Solution
A single switching element is used to simultaneously lock or unlock multiple functional devices, including the rotary device, horizontal spring device, folding device, and vertical spring device, allowing for easy adjustment of the vehicle seat settings based on the driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple actuating elements are used to lock and unlock rotating and horizontal spring mechanisms, then the locking and unlocking function is achieved, but the operation becomes cumbersome and inefficient
Solution Approach 1:
The patent combines multiple actuating elements into a single common actuating element that simultaneously controls the locking and unlocking of both the rotating device and the horizontal spring device. This merging reduces the number of operations required while maintaining the reliability of the locking and unlocking functions.
Solution Approach 2:
The common actuating element is designed to perform multiple functions: it simultaneously actuates the rotating device and the horizontal spring device for locking and unlocking operations. This multi-functionality eliminates the need for separate actuating elements for each device.
2Adaptability or versatility
If multiple actuating elements are used to manage locking and unlocking of different devices, then each device can be controlled independently, but the number of actuating elements increases
Solution Approach 1:
The patent merges multiple actuating elements into a single common actuating element that can simultaneously control multiple devices (rotating device and horizontal spring device), thereby reducing the total number of actuating elements while preserving independent control capability through selective actuation.
Solution Approach 2:
The actuating element is designed with dynamic capabilities to selectively engage different locking mechanisms (first locking mechanism for rotating device, second locking mechanism for horizontal spring device) based on the desired operation, allowing flexible control without increasing the number of physical actuating elements.
3Measurement precision
If multiple actuating elements are used for locking and unlocking mechanisms, then precise control is achieved, but the ease of operation during terrain transitions deteriorates
Solution Approach 1:
The patent combines multiple actuating elements into a single common actuating element that maintains precise control over both the rotating device and horizontal spring device while significantly improving ease of operation during terrain transitions, as the driver only needs to manipulate one element instead of multiple elements.

Function Achieved in This Case
This solution simplifies the operation of the vehicle seat by allowing a single actuation to change multiple settings, enhancing ease of use and safety during transitions between on-road and off-road driving, while ensuring optimal seat function and driver comfort.
