Vehicle Headrest With Swiveling Side Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headrests for vehicle seats often compromise between functionality, comfort, and construction size, failing to provide secure and adjustable support for various head postures while being simple and cost-effective to produce, with complex mechanisms and multiple components.
Innovation Solution
A headrest design featuring a center part with swiveling side wings connected via a hinge and a retaining strut that allows for easy adjustment between neutral and comfort positions, using a single component for the side wing and retaining strut to reduce complexity and weight, with a fastening mechanism that allows for intuitive operation and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components are used for side wings and retaining mechanisms, then adjustment functionality is improved, but device complexity increases
Solution Approach 1:
The side wing and retaining strut are merged into a single integrated component that performs both functions simultaneously. The side wing element includes both the head support surface and the retaining strut structure, eliminating the need for separate components and reducing assembly complexity while maintaining full adjustment functionality.
Solution Approach 2:
The integrated side wing component serves multiple functions: it provides head support, acts as a retaining mechanism, and enables position adjustment. This multi-functional design replaces what would traditionally require multiple separate components, thereby reducing device complexity while preserving adaptability.
2Adaptability or versatility
If swiveling side wings are added to improve head support, then comfort is improved, but ease of operation deteriorates due to complex adjustment mechanisms
Solution Approach 1:
The side wing is designed with dynamic swiveling capability that allows automatic positioning. The swiveling mechanism enables the side wing to move between a neutral position (when not in use) and a comfort position (when a user's head is placed on it), providing adaptive head support without requiring complex manual adjustment operations.
Solution Approach 2:
The swiveling side wing mechanism is designed to self-adjust to the user's head position. When the user places their head on the side wing, it automatically swivels to the appropriate angle to provide optimal support, eliminating the need for the user to manually adjust the mechanism.
3Adaptability or versatility
If side wings are designed to swivel between neutral and comfort positions, then comfort is improved, but construction size increases
Solution Approach 1:
The side wing utilizes a swiveling mechanism that allows it to transition between a compact neutral position (flush with the headrest body) and a deployed comfort position. This dynamic design enables the side wing to provide extended comfort functionality without permanently increasing the headrest's construction size.
Solution Approach 2:
The side wing is designed to nest into the headrest body when in the neutral position, similar to a nested doll structure. This allows the side wing to be stored within the contours of the main headrest, minimizing the overall construction size while still providing additional comfort features when deployed.

AI summary
A headrest for a vehicle seat includes a center part and at least one side wing disposed on a side of the center part in a movable manner between a neutral position and a range of comfort positions. A retaining strut is coupled to the side wing at a living hinge disposed on a first end of the retaining strut. The retaining strut is further coupled to the center part in a longitudinally movable manner at a second end of the retaining strut.
