Therapeutic cushions and systems for using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing therapeutic cushions, such as those described in U.S. Pat. No. 6,782,573, primarily focus on inflating bladders in series to aid blood circulation but lack innovative strategies for enhanced comfort, massaging action, and effective venting systems for cooling and drying users.
Innovation Solution
A therapeutic cushion system featuring a cushion body with columnar inflatable risers, a fluid reservoir, and an inflation/deflation system with electrically actuated valves to produce rearwardly advancing waves for enhanced blood circulation, combined with a venting system for cooling and drying, utilizing a manifold and venting channels to direct airflow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inflatable bladders are inflated one after another in series to help circulate blood, then blood circulation is improved, but the device lacks enhanced comfort and massaging action
Solution Approach 1:
The cushion is divided into multiple independent inflatable cells arranged in series, where each cell can be inflated or deflated independently to create wave-like motion patterns that provide both blood circulation benefits and massaging comfort
Solution Approach 2:
The system transitions from static inflation to dynamic sequential inflation, creating moving wave patterns that propagate through the cushion to provide rhythmic massaging action while maintaining blood circulation benefits
2Ease of manufacture
If traditional cushion structures are used, then manufacturing is simple, but effective venting systems for cooling and drying users are lacking
Solution Approach 1:
The cushion incorporates porous foam material that allows air to pass through, enabling effective venting and cooling of users while maintaining the simple cushion structure
Solution Approach 2:
The cushion is segmented into multiple cells with interconnected air passages, creating a network that facilitates air flow for cooling and drying while keeping the overall structure simple to manufacture
3Adaptability or versatility
If columnar inflatable risers are used to produce advancing waves, then comfort and massaging action are enhanced, but device complexity increases
Solution Approach 1:
The system uses periodic inflation and deflation cycles of the columnar risers to create advancing waves, providing rhythmic massaging action while managing complexity through regular repeating patterns
Solution Approach 2:
The cushion design allows air to flow through interconnected passages and vent through the porous material, enabling self-regulating pressure distribution that reduces the need for complex active control systems

AI summary
Therapeutic cushions having a plurality of inflatable columnar cells, pumping mechanism, and a manifold or valve system for moving a fluid between the pumping mechanism and the inflatable columnar cells. The inflatable columnar cells are constructed such that inflation and deflation of the cells cause vertical expansion/contraction of the cells with limited lateral expansion/contraction. The manifold or the valve system connect the pumping mechanism with the inflatable columnar cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable columnar cells to produce rearwardly advancing waves. A venting manifold may vent air from the cells between the cushions.
