Adjustable Car Seat Lumbar Pillow Structure for Body Fit
Solution Overview
Problem
Existing vehicle-mounted lumbar support pillows are difficult to effectively fit and adjust for individuals of different heights and weights, limiting their usability and comfort.
Innovation Solution
A vehicle-mounted detachable lumbar support pillow structure that includes a sliding assembly and connecting member, allowing the car seat cushion to be adjusted upwards and downwards, with serrations and damping mechanisms to secure the optimal position, and a disassembly feature for easy cleaning and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lumbar support pillow is purchased directly and placed on car seats, then the pillow can provide basic lumbar support, but it is difficult to effectively fit and adjust for individuals of different heights and weights
Solution Approach 1:
The lumbar support pillow is designed with a sliding mechanism that allows it to move vertically along the car seat backrest. The connecting member with docking stand enables the pillow to be positioned at different heights, adapting to users of various heights and body types. This dynamic adjustment capability transforms a static pillow into an adaptable support system.
Solution Approach 2:
The lumbar support pillow is divided into separable components: the pillow itself, the connecting member with docking stand, and the sliding mechanism. This segmentation allows the pillow to be detached for cleaning or replacement while keeping the mounting structure intact, and enables independent adjustment of each component for optimal fit.
2Ease of repair
If the lumbar support pillow is made detachable for easy cleaning and replacement, then maintenance becomes simpler, but the structure becomes more complex
Solution Approach 1:
The pillow is designed as a detachable component separated from the mounting structure through the connecting member. This segmentation allows the pillow to be easily removed for cleaning or replacement without affecting the sliding mechanism or car seat structure, simplifying maintenance while maintaining a relatively simple overall design.
Solution Approach 2:
The connecting member with docking stand serves multiple functions: it attaches the pillow to the sliding mechanism, enables vertical adjustment, and provides a detachable connection for easy removal. This multi-functionality reduces the need for additional complex components while achieving ease of maintenance.
3Adaptability or versatility
If the sliding groove length is increased to allow greater adjustment range, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The sliding groove is designed with serrations only in specific regions where adjustment positioning is needed, rather than along the entire length. This localized feature provides adequate adjustment range for different body types while keeping the overall structure simple and avoiding unnecessary complexity in the sliding mechanism.
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 adjustable design enhances comfort by accommodating various body types, improves the fit of the lumbar support, and facilitates easy maintenance and replacement of components.
Implementation Method 1
a first spring and a fastener disposed inside the docking stand, the fastener is located above the first spring... the fastener and the first spring form an elastic abutting state
Implementation Method 2
spherical columns and second springs are embedded and mounted at positions in a horizontal direction of the docking stand corresponding to the cambered grooves, and the second springs are located behind the spherical columns
Implementation Method 3
two opposite ends of the base are both provided with the movable toothed clamping blocks and third springs, the third springs are located behind the movable toothed clamping blocks, the movable toothed clamping blocks and the third springs are abutted against each other
