Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side pillows for vehicle seats lack functionality to accommodate different head deflections of passengers, requiring manual adjustment for comfort, which is not universally effective.
Innovation Solution
A multifunctional side pillow assembly with adjustable components, including rotating blocks, sliding grooves, and clamping assemblies, allowing for customizable positioning and adjustment to fit various head deflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If side pillows are rotationally installed on two ends of the fixed bar, then the side pillows can be positioned at two ends of the headrest or two sides of the passenger head, but the side pillows are single in function and cannot accommodate different head deflections
Solution Approach 1:
The side pillow structure is transformed from a fixed rotational installation to a dynamically adjustable sliding mechanism. The fixing frame with sliding groove allows the side pillow to move along the outer wall of the rotating block, enabling continuous position adjustment to accommodate different head deflections while maintaining a relatively simple overall structure.
Solution Approach 2:
The side pillow assembly is divided into multiple independent components: rotating block, fixing frame, sliding groove, and clamping assembly. This segmentation allows each component to perform its specific function independently, achieving multi-position adjustment capability without significantly increasing overall structural complexity.
2Reliability
If clamping assembly is elastically disposed on the fixing frame to increase sliding friction, then the side pillow can be securely positioned during adjustment, but the sliding friction increases
Solution Approach 1:
The clamping assembly uses an elastic component (spring) to dynamically adjust the clamping force on the rotating block. When adjustment is needed, reduced clamping force allows easy sliding; when positioning is required, increased clamping force secures the position. This parameter change approach achieves reliable positioning without requiring excessively high sliding friction throughout the entire range of motion.
3Ease of operation
If first adjusting assembly is used to make the fixing frame slidably disposed on the rotating block, then the side pillow can be adjusted to meet individual comfort needs, but the device complexity increases
Solution Approach 1:
The first adjusting assembly utilizes the elastic property of the clamping assembly to automatically clamp the rotating block when the side pillow is pulled or pushed. The spring-loaded mechanism provides self-service clamping without requiring additional actuators or complex control systems, achieving easy adjustment operation with relatively simple assembly structure.

Implementation Method 5
the third limiting spring is configured to exert an outward groove force on the third limiting block
Implementation Method 6
the fourth limiting spring is configured to exert an upward force on the spring column
Implementation Method 7
the fifth limiting spring is disposed on an end of the limiting piece

AI summary
A multifunctional side pillow assembly is provided, including two rotating blocks and two side pillows. The side pillows are slidably disposed on outer walls of the rotating blocks through fixing frames and sliding grooves. Each fixing frame is slidably disposed on the corresponding rotating block through an adjusting assembly in a limited manner, and a clamping assembly is elastically disposed on the fixing frame for increasing a sliding friction on the rotating block. The side pillow slides along the outer wall of the rotating block through the fixing frame; when the limiting block is detached from a limiting groove, a limiting spring is thereby contracted, and then the limiting block slides and a spring block also slides; and when the limiting block slides to another limiting groove, the limiting block is clamped therein under an action of the limiting spring.
