Position-adjustable cervical vertebrae support apparatus capable of being installed in back of vehicle seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle seats often lead to an incorrect driving posture due to the separation of cervical vertebrae from the seat back, causing driver fatigue and potentially hazardous driving conditions.
Innovation Solution
A position-adjustable cervical vertebrae support apparatus is installed on the vehicle seat, featuring a cervical vertebrae supporting member with a front-back distance adjusting unit and an up-down distance adjusting unit, allowing the cervical vertebrae to be adjusted and supported according to the driver's body characteristics, using a motor-driven screw system and cylinder mechanism for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver uses a conventional vehicle seat, then the seat can support the driver's body within limited space and weight ranges, but the cervical vertebrae separate from the seat back causing incorrect driving posture
Solution Approach 1:
The invention divides the seat into functional segments: the conventional seat base and backrest for general support, and a separate cervical vertebrae support unit with independent adjustment capabilities. This segmentation allows the cervical support to be positioned independently to match the driver's body characteristics, resolving the contradiction between general seat support and specific cervical vertebrae support.
Solution Approach 2:
The cervical vertebrae support unit incorporates dynamic adjustment mechanisms including a motor-driven screw system for front-back positioning and a cylinder mechanism for up-down adjustment. These dynamic elements enable the support position to be adapted to different drivers and driving conditions, maintaining reliable cervical vertebrae support while accommodating various operating requirements.
2Manufacturing precision
If the cervical vertebrae supporting member is made adjustable with motor-driven screw system and cylinder mechanism, then precise positioning is achieved, but the device complexity increases
Solution Approach 1:
The invention replaces manual adjustment mechanisms with automated motor-driven systems. The motor-driven screw system and cylinder mechanism automatically position the cervical support member based on control signals, achieving high positioning precision without requiring complex manual adjustment interfaces. This substitution reduces operational complexity while maintaining manufacturing precision.
Solution Approach 2:
The motor-driven screw system and cylinder mechanism serve multiple functions: they provide both front-back and up-down adjustment capabilities, enable positioning for different driver sizes, and can be controlled through various interfaces. This multi-functionality reduces the need for separate adjustment mechanisms, thereby reducing overall device complexity while maintaining positioning precision.
