Foldable Tensegrity Modules for Accessible Coastal Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temporary structures for accessing maritime coastlines are inadequate for users with reduced mobility, as they are either difficult to install, require significant anchoring, or have low load capacity, and existing tensegrity structures are not easily scalable or modular for large platforms.
Innovation Solution
A foldable tensegrity structure comprising modules with hinged bars and nodes connected by tension and compression elements, allowing for easy assembly and disassembly, and featuring adjustable nodes and crutches for support, enabling the creation of large, stable, and versatile platforms without permanent anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed structures are used for accessible coastline access, then accessibility for users with reduced mobility is improved, but the installation site is permanently impacted and environmental protection obligations are violated
Solution Approach 1:
The structure is divided into modular components that can be assembled and disassembled. The platform consists of separate floating modules connected by articulation points, allowing the system to be transported and installed without permanent ground anchoring, thus avoiding environmental damage while providing accessible coastline access
Solution Approach 2:
The structure employs dynamic, adjustable components including articulation points that allow movement between folded and deployed states. The platform can be easily assembled and disassembled at the installation site, transforming from a compact transport state to a functional access structure without permanent impact on the environment
2Object-affected harmful factors
If demountable floating pontoons are used, then environmental impact is reduced, but stability is poor and substantial anchoring is required
Solution Approach 1:
Multiple floating modules are connected together through articulation points to form a unified, stable platform. The combination of modules creates mutual support and distribution of forces, achieving stability without requiring substantial anchoring to the seabed, thus maintaining environmental protection while solving the stability issue
Solution Approach 2:
The modules are pre-assembled with articulation points and connection mechanisms that enable stable configuration upon deployment. The structure is designed to self-stabilize when assembled, with the articulation points naturally positioning the modules in a stable arrangement without requiring additional anchoring actions
3Strength
If modular scaffolding systems are used, then load capacity is improved, but the number of components increases and assembly becomes time-consuming and labor-intensive
Solution Approach 1:
Multiple structural functions are merged into integrated modules that combine support, articulation, and connection capabilities in single components. This reduces the total number of separate parts compared to traditional scaffolding systems while maintaining load capacity, and the pre-integrated design significantly reduces assembly time and labor requirements
4Weight of moving object
If traditional tensegrity structures are used, then lightweight properties are achieved, but modularity and scalability for large platforms are limited
Solution Approach 1:
The tensegrity structure is segmented into repeating modular units that can be independently manufactured and then assembled into larger configurations. Each module maintains the lightweight tensegrity characteristics while the modular design enables scaling to large platform sizes by simply adding more units, solving both the weight and adaptability requirements

Implementation Method 1
Tensegrity is the ability of a structure to stabilize itself through the interplay of tensile and compressive forces that are distributed and balanced within it
Implementation Method 2
by connecting bars with cables, without directly connecting the bars to each other, a rigid system can be created
Implementation Method 3
a mechanical system comprising a discontinuous set of compressed components within a continuum of tensioned components

AI summary
The invention concerns a method for assembling a set of foldable/unfoldable tensegrity modules, each comprising a plurality of bars (10), a plurality of nodes (40) allowing the articulation of the bars (10), the method being characterised in that it comprises: - juxtaposing the modules such that two adjacent modules comprise nodes positioned one over the other in a vertical plane; - linking said nodes of the two adjacent modules by means of a tension cable and support beam link; - positioning cover elements extending between successive modules.
