Hybrid Bladder Material Layout for Variable Elasticity and Leak Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing hybrid materials with varying elastomeric capabilities are costly and difficult to implement, particularly in cell flow technology, leading to unsightly and uncomfortable products with potential leaks.
Innovation Solution
A process involving the formation of homogenous inner bladders from a first material with varying elasticity, where a second material with reduced elasticity is applied to the exterior, either molded, laminated, or silk-screened, to create hybrid bladders that can be fluidly connected, reducing elasticity and enhancing heat dissipation and air circulation, and arranged in variable patterns for ergonomic benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple materials are combined to create hybrid materials with different elastomeric capabilities, then the ability to control elongation and achieve varied densities is improved, but the manufacturing cost and complexity increase significantly
Solution Approach 1:
The patent applies local quality by depositing a second material with different elastomeric properties onto specific regions of the first material substrate. This creates zones with varying elastomeric capabilities within a single continuous bladder structure, allowing different parts of the cushion to have different elongation characteristics without requiring multiple separate materials or complex assembly processes
Solution Approach 2:
The patent creates composite materials by combining a first material substrate with a second material that has different elastomeric properties. The second material is deposited in patterns or zones on the first material to create hybrid regions with controlled elongation characteristics, achieving material versatility through composite construction rather than assembling multiple separate components
2Adaptability or versatility
If multiple layers and variable quantities of layers are bonded to create hybrid bladders, then different elastomeric capabilities are achieved, but the ability to create tight seals and leak-proof bladders deteriorates
Solution Approach 1:
The patent uses a single continuous flexible bladder formed from a first material substrate that maintains structural integrity and sealability. Instead of bonding multiple separate layers to create hybrid bladders, the second material is deposited directly onto the substrate to create elastomeric variation while preserving the continuous sealed structure, eliminating leak paths that would occur at layer boundaries
3Adaptability or versatility
If valves and channels are used to separate bladders with different materials, then varied densities and elastomeric capabilities are achieved, but the product becomes costly and visually unappealing
Solution Approach 1:
The patent merges multiple elastomeric capabilities into a single continuous bladder structure by depositing a second material onto a first material substrate. This eliminates the need for separate bladders, valves, and channels, creating a unified structure that provides varied elastomeric properties throughout while maintaining visual appeal and reducing component complexity
Solution Approach 2:
The patent creates a composite bladder structure where a second material with different elastomeric properties is deposited onto a first material substrate in specific patterns or zones. This produces a single integrated component with spatially varying elastomeric capabilities, replacing the need for multiple separate components connected by valves and channels

Function Achieved in This Case
The solution results in a cost-effective, leak-proof, and comfortable product with controlled elongation characteristics, suitable for applications like shoe soles and helmets, providing ergonomic benefits and improved user experience.
Implementation Method 1
a second material having a second elasticity is placed on the exterior surface of at least one hybrid bladder. The second elasticity is less than the first elasticity and the second material reduces the elastic qualities of one or more of hybrid bladders
Implementation Method 2
The second material can be one of the following: molded; laminated; cast; or silk screened. In at least one embodiment, second material increases heat dissipation across one or more of the hybrid bladders
Implementation Method 3
The variable pattern can dampen vibrations across one or more of the hybrid bladders

AI summary
A process of making a family cell of homogenous inner bladders with varying elasticity includes a forming a plurality of inner bladders from a first material with a first elasticity. The inner bladders have interior surfaces during inner chambers and exterior surfaces exposed to an outside environment. The inner chambers are configured to store a fluid. A family cell is formed by fluidly connecting the inner bladders. One or more hybrid bladders are selected from the inner bladders and a second material having a second elasticity is applied to the hybrid bladders. The second elasticity is less than the first elasticity, such that the second material reduces the elastic qualities of the hybrid bladder.
