Pneumatic pocket and application thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic pockets in cushion bodies are prone to flipping or displacement under external force, and their manufacturing process is inefficient and costly due to the need for precise counter bores or hollowed-out portions, which increases mold costs and waste processing expenses.
Innovation Solution
The pneumatic pockets are manufactured through blow molding with a staggered arrangement of responding and assembly portions, allowing them to telescope and expand to accommodate external forces without flipping, and are assembled using a square frame configuration with locking elements for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pneumatic pockets are mounted in a side-by-side manner inside a cushion body, then the cushion body provides resilient buffering and sensitive response, but the pneumatic pockets are prone to flipping or displacement under external force
Solution Approach 1:
The patent applies nesting by placing the pneumatic pocket inside a pocket bag that is integrated into the cushion body structure. The pocket bag acts as a container that holds the pneumatic pocket in a fixed position, preventing flipping or displacement while allowing the pocket to function. This nested arrangement ensures the pocket remains securely positioned within the cushion body during use.
Solution Approach 2:
The patent implements preliminary action by pre-forming the pocket bag with an opening direction oriented toward the head portion of the cushion body during manufacturing. This predetermined orientation is established before the pneumatic pocket is inserted, ensuring proper positioning and preventing displacement. The pocket bag is prepared in advance with the correct structural configuration to guide and secure the pocket in the intended position.
2Reliability
If counter bores or hollowed-out portions are manufactured in top pads and bottom pads to position pneumatic pockets, then the pockets are prevented from flipping or displacing, but the manufacturing process becomes slow and inefficient with high mold costs and waste processing expenses
Solution Approach 1:
The patent merges the positioning function into the pocket bag structure itself rather than requiring separate counter bores in the top and bottom pads. The pocket bag is formed as a single integrated component that provides both structural support and positioning functionality. This consolidation eliminates the need for multiple separate manufacturing operations on different components, thereby improving manufacturing efficiency while maintaining reliable pocket positioning.
Solution Approach 2:
The patent extracts the positioning function from the traditional counter bore structure and relocates it to the pocket bag. Instead of modifying the top and bottom pads with precise counter bores, the positioning capability is taken out and embodied in the pocket bag's design, including its opening direction and structural configuration. This extraction simplifies the overall manufacturing process by concentrating the positioning function in a single component that can be more efficiently produced.
3Device complexity
If large molds are utilized for production of cushion bodies with integrated counter bores, then the cushion body structure is simplified, but the mold costs are relatively high and it is difficult to maintain the precision of the counter bores
Solution Approach 1:
The patent segments the cushion body into distinct functional components: the pocket bag, the top pad, and the bottom pad. Rather than integrating the positioning structure into the main cushion body mold, the positioning function is separated and embodied in the pocket bag component. This segmentation allows each component to be manufactured with appropriate precision requirements, avoiding the need for complex large-scale molds while maintaining the necessary precision for pocket positioning.

Function Achieved in This Case
The solution provides stable, efficient assembly and buffering without displacement, reducing manufacturing costs and improving economic efficiency by eliminating the need for additional cutting processes.
Implementation Method 1
The responding portion allows a top portion to be deformed and telescoped towards a bottom portion for bearing an external force and driving an existed through hole to intake or discharge air in response
Implementation Method 2
a pneumatic pocket manufactured through blow molding, which pocket body has a responding portion and an assembly portion provided in a staggered manner

AI summary
A pneumatic pocket, manufactured by blow molding, has a top portion, a bottom portion, a pocket body connected between the top portion and the bottom portion, defining an air chamber therein, and a through hole communicating the air chamber and the outside. The pocket body has a responding portion and an assembly portion formed in the pocket body in a staggered manner. The responding portion allows the top portion to be deformed and telescoped towards the bottom portion for bearing an external force and driving the through hole to intake or discharge air in response. The assembly portion is configured to allow another pneumatic pocket to be positioned and assembled without interfering the deforming and telescoping of the responding portions thereof, so that the pneumatic pocket can be extended and expanded according to the size of a cushion body side by side, so that the pneumatic pockets can be arranged in the cushion body parallelly side-by-side.
