Solution Overview
Problem
Existing reconfigurable structures are limited in their ability to adapt to various circumstances and environmental conditions, as they typically follow predetermined patterns and lack the capability to respond dynamically to external forces and stimuli.
Innovation Solution
An adjustable structure comprising arrays of beams connected by tension joints with adjustable tension lines, allowing for multiple configurations through the use of extendable and retractable rods with varying densities and connections to facilitate both coarse and fine adjustments, and incorporating a control system for dynamic response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reconfigurable structures use predetermined patterns with carriages on rails and hinges, then the structure maintains simplicity and ease of manufacture, but the adaptability to respond to different circumstances and environmental conditions is limited
Solution Approach 1:
The structure transitions from static predetermined patterns to dynamic reconfigurability through tension joints with adjustable tension lines. Each joint can independently adjust its tension characteristics, allowing the structure to dynamically adapt its configuration in response to external forces and environmental conditions while maintaining structural integrity.
Solution Approach 2:
The invention changes the physical parameter of tension in the connection lines from fixed to adjustable. By incorporating tension adjustors that modify the tension characteristics of flexible lines, the structure can vary its mechanical properties and configuration states, enabling adaptation to different circumstances without requiring complex predetermined mechanisms.
2Adaptability or versatility
If tension joints use fixed tension lines, then the structure maintains simplicity and ease of operation, but the ability to adjust configuration and respond to different requirements is reduced
Solution Approach 1:
The structure divides the tension adjustment function into discrete, modular tension adjustors located at individual joints. Each adjustor is an independent unit that can be operated separately, allowing localized configuration changes without affecting the entire structure. This segmentation maintains ease of operation by providing simple, localized adjustment mechanisms while achieving high configurability.
3Manufacturing precision
If the structure uses densely packed rods in multiple layers, then the manufacturing precision and structural control are improved, but the device complexity and number of components increase
Solution Approach 1:
The invention implements a multi-layer structure where densely packed rods in the second layer are nested within or between the rods of the first layer. This nesting arrangement achieves high structural control and manufacturing precision by creating a hierarchical organization of components, where the second layer provides fine adjustment capability while the first layer provides coarse adjustment, reducing the need for completely separate systems.
