Vehicle Headrest with Pivotable Wing for Continuous Contact Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headrests lack a large contact surface in non-use positions and do not meet safety and aesthetic requirements effectively, with gaps in the central region disrupting the head contact surface.
Innovation Solution
A headrest with a base body and a pivotable wing, where the wing moves between first and second positions to form different head contact surfaces, providing a continuous surface in the first position and a large lateral contact surface in the second position, with a cushion integrated between the wing and base for enhanced comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the headrest uses a traditional design with side bolsters that are recessed in the non-use position, then the design is simple, but the contact surface is small and not continuous
Solution Approach 1:
The headrest incorporates a movable wing element that can pivot between different positions. In the first position, the wing provides a large continuous contact surface for head support. In the second position, the wing moves away to create a recessed appearance. This dynamic movement allows the headrest to achieve both a large contact surface and a simple recessed design aesthetic at different times, resolving the contradiction between contact surface area and structural complexity.
2Ease of operation
If the headrest provides lateral support in the non-use position, then comfort is improved, but the head contact surface may be interrupted by gaps
Solution Approach 1:
The headrest is divided into separate functional elements: a base body and a movable wing. The wing can be positioned in different locations relative to the base body. In the first position, the wing and base body work together to form a continuous head contact surface providing both lateral and rear support. In the second position, the wing moves away while the base body maintains a recessed appearance. This segmentation allows the headrest to provide continuous support when needed while maintaining aesthetic simplicity when not in use.
