Inflatable Neck Support Module for Headrest Massage and Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle seat occupants experience discomfort and pain due to inadequate neck support during long journeys, particularly in autonomous motor vehicles, where existing headrests fail to provide sufficient support and massage functionality.
Innovation Solution
A neck support module comprising multiple inflatable pouches fixed to a frame, with a pump and electronic control unit for sequential inflation to provide massage-like support, allowing the neck to be supported and alleviating discomfort by distributing pressure evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional headrest is used, then the head is supported, but the neck is not adequately supported causing discomfort and pain
Solution Approach 1:
The neck support module is divided into multiple inflatable pouches (at least two, preferably four or six) arranged in sequence along the neck support surface. Each pouch can be independently inflated and deflated, allowing segmented pressure application to different regions of the neck, thereby providing comprehensive support and massage functionality to address neck discomfort effectively
Solution Approach 2:
The invention uses an inflatable pouch system controlled by a pump and electronic control unit. The pouches can be selectively inflated and deflated to provide dynamic support and massage pressure to the neck. This pneumatic system allows adjustable pressure distribution along the neck, enabling both support and therapeutic massage functions to eliminate neck pain and cramps
2Adaptability or versatility
If multiple inflatable pouches are added for massage functionality, then neck massage capability is improved, but device complexity increases
Solution Approach 1:
The inflatable pouch system serves multiple functions: it provides neck support, delivers therapeutic massage through sequential inflation, and offers adjustable pressure distribution. The same pneumatic system and control unit that manage the multiple pouches enable both support and massage functions, making the device multi-functional without requiring separate mechanical systems for each function
Solution Approach 2:
The electronic control unit enables independent control of inflation pressure and timing for each pouch. By varying the pressure parameters and inflation sequence, the system can switch between different massage modes and support levels. This parameter-based control allows versatile functionality while using a relatively simple pneumatic system structure
3Adaptability or versatility
If sequential inflation of pouches is implemented for massage, then massage effect is improved, but control system complexity increases
Solution Approach 1:
The electronic control unit implements periodic inflation and deflation cycles of the pouches in a predetermined sequence. This periodic action creates a rhythmic massage effect on the neck, with each pouch being inflated for a specific duration and then deflated before the next pouch is activated. The sequential periodic operation of multiple pouches produces a wave-like massage pattern that is therapeutically effective while using a straightforward control logic
