Inflatable lumbar support cushion for seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable lumbar support cushions for seats lack a manual or electric pump unit integrated with the seat cushion, failing to provide efficient and economical comfort and pain relief for users.
Innovation Solution
An inflatable lumbar support cushion system comprising a seat cushion assembly, an air bladder assembly, and a pump unit assembly, where the air bladder is inflated using a manual or electric pump unit, providing adjustable and portable comfort for various seating types, including driver seats and wheelchairs, with a detachable design and affordable maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inflatable lumbar support cushion is designed without an integrated pump unit, then the device complexity is reduced and manufacturing cost is lowered, but the ease of operation deteriorates because users cannot efficiently inflate the cushion
Solution Approach 1:
The patent combines the pump unit with the seat cushion assembly, integrating the inflation mechanism directly into the cushion structure. This allows users to inflate the lumbar support portion conveniently while maintaining a unified, manageable device design that does not excessively increase complexity.
Solution Approach 2:
The patent introduces an air hose as an intermediary component connecting the pump unit to the air bladder. This mediator enables efficient air transfer for inflation while keeping the pump unit externally mounted, thus improving ease of operation without significantly increasing overall device complexity.
2Adaptability or versatility
If a fixed lumbar support design is used, then the manufacturing precision is simplified, but the adaptability deteriorates because it cannot accommodate different seating positions or user preferences
Solution Approach 1:
The patent employs an inflatable air bladder that can dynamically adjust its volume and firmness based on user needs. This dynamic design allows the lumbar support to adapt to different seating positions and preferences, while the manufacturing process remains relatively simple as it only requires producing the bladder in various sizes rather than creating complex adjustable mechanical structures.

AI summary
An inflatable lumbar support cushion for seats including a seat cushion assembly connected with an air bladder that has a hollow body and is covered by a lumbar support that is hollow. The air bladder is inflated by a pump unit assembly which includes a pump unit that blows air to the air bladder by an air hose adapting the size of the lumbar support as required and defining a lumbar support portion which provides comfort to a user. The air bladder configured as a cushion for a sofa. The pump unit can be electronic or manual. The seat cushion can be adapted to different seats by an attaching base located to a bottom surface thereof and the lumbar support may be attached to a backrest by a strap allowing to fasten the inflatable lumbar support cushion to any suitable seat.
