Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastomeric material applications lack the ability for post-assembly tension adjustment, limiting customization to individual user needs and accommodating material deformation, as they rely on pre-tensioning that cannot be altered after assembly.
Innovation Solution
Incorporation of tension adjustment assemblies, such as bladders and mechanical extension/retraction systems, that allow for selective inflation, deflation, or manual/motorized adjustment of elastomeric material tension through fluidic or mechanical means, enabling post-assembly control of support characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-tensioning is employed to facilitate support characteristics, then support performance is improved, but adaptability to different users and conditions deteriorates
Solution Approach 1:
The patent applies dynamics by transforming the static pre-tensioning system into a dynamic one through tension adjustment assemblies. These assemblies include mechanisms such as threaded rods with nuts, spring-loaded adjusters, or hydraulic/pneumatic actuators that enable the elastomeric material tension to be modified after assembly. This allows the support characteristics to adapt to different users and conditions while maintaining reliable support performance.
Solution Approach 2:
The patent employs parameter changes by enabling modification of the tension parameter in the elastomeric material after assembly. Through adjustment mechanisms, the tension level can be increased or decreased to accommodate different user preferences, body types, and usage conditions. This transforms a fixed-parameter system into a variable-parameter system, resolving the contradiction between reliable initial support and adaptability.
2Reliability
If variable pre-tensioning is employed to provide varying support levels, then support characteristics are improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the tension adjustment function into discrete, modular assemblies positioned at specific locations within the elastomeric material structure. Each tension adjustment assembly operates independently, allowing for localized tension modification without affecting the entire system. This modular approach enables variable support characteristics while managing complexity through standardized, replaceable components.
3Adaptability or versatility
If post-assembly tension adjustment is enabled, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by designing tension adjustment assemblies that enable users to independently adjust tension levels without requiring specialized tools or technical expertise. The adjustment mechanisms are positioned for easy access and designed with intuitive operation, allowing end-users to customize the support characteristics according to their needs. This self-adjustment capability enhances adaptability while avoiding the complexity of automated control systems.

AI summary
An arrangement for enabling post-assembly tension adjustment in an elastomeric material application. The arrangement can have a frame structure and a panel of elastomeric material, such as elastomeric mesh, retained to span from a first side to a second side of the frame structure in tension. A tension adjustment assembly enables a post-assembly, selective deflection of the panel of elastomeric material and thus the tension in the panel of elastomeric material. The tension adjustment assembly can, for example, employ a selectively inflatable bladder, an extension and retraction arrangement with a biasing portion, a pivoting member, a laterally slidable member, a roller with a non-concentric pivot axis a deflection member with a tip portion disposed to an outer surface side of the panel of elastomeric material, or a deflection member slidable on an inclined surface in relation to the panel of elastomeric material.
