Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incorrect driving posture due to mismatch between driver's body characteristics and vehicle seat design leads to driving fatigue, increasing the risk of accidents from impaired judgment.
Innovation Solution
A position-adjustable cervical vertebrae support apparatus installed on vehicle seats, featuring a cervical vertebrae supporting member with front-back and up-down adjusting units, limits movement and provides support to align the neck with the seat, optionally incorporating heating and vibration for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat design is used, then the structure is simple and cost-effective, but it cannot adapt to different driver body characteristics leading to incorrect driving posture
Solution Approach 1:
The seat back is divided into multiple sections including a cervical vertebrae support section, lumbar support section, and adjustable headrest. The cervical support section includes a support plate with adjustable positioning mechanisms that can be independently adjusted to match different driver neck positions and body characteristics, allowing customized support without redesigning the entire seat structure.
Solution Approach 2:
The seat incorporates adjustable components such as the cervical support plate that can move between fixed and adjustable states. The support plate can be positioned at different heights and angles through adjustment mechanisms, enabling the seat to adapt dynamically to various driver body types while maintaining structural integrity.
2Reliability
If the cervical vertebrae support position is fixed, then the structure is simple, but it cannot maintain stable driving posture for drivers with different body characteristics
Solution Approach 1:
The seat provides preliminary adjustment options for the cervical support plate position and angle before the driver sits down. The adjustment mechanisms allow pre-positioning of the support plate at multiple predetermined locations, enabling drivers to find their optimal position quickly without complex real-time adjustments during driving.
Solution Approach 2:
The seat includes self-adjusting features such as adjustable headrests and cervical support plates that drivers can easily reposition themselves. The design incorporates simple adjustment mechanisms that allow drivers to maintain their own driving posture without requiring external assistance or complex automated systems.
3Ease of operation
If no cervical vertebrae support is provided, then the seat structure remains simple, but driving fatigue increases due to incorrect posture
Solution Approach 1:
The seat provides localized cervical vertebrae support through a dedicated support plate and headrest system positioned specifically at the neck and head region. This localized support targets the critical area for posture correction without requiring complex modifications to the entire seat structure, maintaining simplicity while improving comfort.
Solution Approach 2:
The cervical support plate acts as an intermediary element between the seat back and the driver's cervical vertebrae. It provides the necessary support and adjustment capabilities while isolating the complexity of the adjustment mechanisms from the main seat structure, allowing for easier integration and maintenance.
