Automobile Side Back Cushion Width Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile side back cushions require external tools for mounting and dismounting, are inflexible, and wasteful in packaging due to their integral design, failing to provide adequate side protection for passengers during accidents.
Innovation Solution
An adjustable automobile side back cushion system with a mounting rod, chutes, and an adjusting channel, featuring a width adjusting structure with fastening frames, gear bars, and an adjusting knob, allowing for tool-free adjustment and easy disassembly, adaptable to different headrest distances without the need for external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external tool is required for mounting or dismounting the side back cushion, then the mounting and dismounting process is reliable, but time and labor are wasted and it becomes inconvenient when the tool is forgotten
Solution Approach 1:
The side back cushion incorporates a self-service adjusting mechanism where the user can directly operate the adjusting gear and gear bars without external tools. The manual adjustment system allows the cushion to be mounted, dismounted, and width-adjusted using only hand operations, eliminating the need for screwdrivers or other external tools.
2Device complexity
If the side back cushion is integrally designed, then the structure is simple, but packaging materials are wasted
Solution Approach 1:
The side back cushion is divided into separable components including the mounting rod, first side cushion, second side cushion, and adjusting mechanism. This segmentation allows the components to be disassembled for compact storage and efficient packaging, reducing the need for excessive packaging materials while maintaining structural integrity during use.
3Reliability
If the side back cushion provides fixed limitation to the head, then head protection is provided during accidents, but it cannot adapt to different headrest distances
Solution Approach 1:
The side back cushion incorporates a dynamic width adjusting mechanism with an adjusting gear and gear bars that allow the cushion width to be changed according to different headrest distances. This dynamic adjustment capability enables the cushion to adapt to various mounting positions while maintaining reliable head protection through the robust mounting rod connection and cushioning structure.
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 system allows for convenient and labor-saving adjustments to fit various headrest models, reducing the need for tools and simplifying storage, while providing flexible side protection for passengers by adapting to different headrest distances and ensuring ease of assembly and disassembly.
Implementation Method 1
an adjusting gear disposed in the adjusting channel; wherein the first fastening, frame and the second fastening frame are disposed in a mirror image manner; the first gear bar and the second gear bar oppositely extend along the adjusting channel and are simultaneously occluded with the adjusting gear, such that the adjusting gear drives the first fastening frame and the second fastening frame to be away from or close to each other
Implementation Method 2
the first rotary connecting member includes a first columnar part connected to the mounting rod and a first screw cap away from the mounting rod and in threaded connection with the first columnar part
