Side Window Head Cushion for Lateral Support and Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headrests do not effectively support a passenger's lateral head, leading to discomfort and inadequate protection against impacts, while also failing to block sunlight and cover the vehicle interior.
Innovation Solution
A head cushion mounted on a vehicle's side window, featuring impact absorption materials, a cushion-mounting mechanism, and optionally a curtain, designed to support the head, provide comfort, and block sunlight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vehicle headrests are used, then the structure is simple, but they cannot effectively support the passenger's lateral head and provide adequate protection against impacts
Solution Approach 1:
The patent transitions from conventional vertical headrests to a lateral head cushion mounted on the side window, changing the spatial dimension of head support from vertical to lateral. This dimensional change enables effective lateral head support while maintaining structural simplicity through the use of a cushion body with impact absorption materials.
Solution Approach 2:
The cushion body is filled with impact absorption materials to provide protection against impacts while maintaining comfort. This composite structure combines the cushioning properties of soft materials with the protective qualities of impact-absorbing materials, achieving both comfort and safety without complex mechanisms.
2Adaptability or versatility
If conventional headrests are used, then the device is simple, but they cannot block sunlight and cover the vehicle interior
Solution Approach 1:
The head cushion is designed to perform multiple functions: supporting the passenger's lateral head, providing comfort during turns, protecting against impacts, and blocking sunlight. By integrating these functions into a single device mounted on the side window, the patent achieves multi-functionality without requiring separate complex systems for each purpose.
Solution Approach 2:
The patent combines head support, impact protection, and sunlight blocking functions into a single integrated cushion structure. The cushion body serves as both the support element and the sunlight barrier, merging multiple protective and comfort functions into one unified device rather than using separate components.
3Reliability
If the cushion body is made thick for better impact absorption, then protection effectiveness improves, but the space occupied increases
Solution Approach 1:
The cushion body utilizes impact absorption materials that provide high protection effectiveness with relatively low volume. These specialized materials offer superior impact absorption properties compared to conventional cushioning materials, enabling effective protection without requiring excessive thickness or volume.
Solution Approach 2:
The cushion body is configured with varying thickness distribution, being thicker at the rear cushion portion for impact absorption and thinner at the upper cushion portion for comfort. This localized quality optimization provides effective impact protection where needed while minimizing overall volume and maintaining comfort in contact areas.

AI summary
A head cushion mounted on a side window of a vehicle that is capable of allowing a passenger's lateral head to be supported thereagainst, thereby making him or her lean comfortably thereon and protecting his or her head from impacts. The head cushion, which is mounted on a side window of a vehicle to support a passenger's head thereagainst, includes: a body whose inside is filled with impact absorption materials; and a cushion-mounting part coupled to the body in such a way as to be separably fixed to the side window of the vehicle.
