Articulating Protective System Resisting Mechanical Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-resistant systems often sacrifice flexibility for protection or vice versa, lacking the ability to simultaneously provide effective protection while allowing for increased ranges of motion.
Innovation Solution
The development of articulating protective systems comprising load-resistant units arranged in rows with peg-and-socket connections, reinforced with compliant fiber arrays, allowing for anisotropic stiffening and enhanced compliance, enabling flexibility while maintaining constant thickness and load resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional load-resistant systems use rigid structures, then protection capability is improved, but flexibility and range of motion deteriorate
Solution Approach 1:
The protective system is divided into multiple discrete load-resistant units arranged in modular rows and columns. Each unit can move independently relative to others through articulation points, allowing the overall structure to flex and conform to body movements while maintaining protective coverage. This segmentation enables the system to provide rigid protection when needed while allowing flexibility during motion.
Solution Approach 2:
The system transitions from static rigid connections to dynamic articulated connections between load-resistant units. The articulation points allow relative movement between units, enabling the protective system to adapt its shape and configuration in response to applied loads and body movements. This dynamic capability maintains protection effectiveness while accommodating ranges of motion.
2Adaptability or versatility
If load-resistant systems are made flexible, then range of motion is improved, but protection capability deteriorates
Solution Approach 1:
Different regions of the protective system have different structural properties. The load-resistant units maintain rigid characteristics for protection, while the articulation points between units provide flexibility. This local differentiation allows the system to exhibit both rigid protection capability and flexible adaptability in appropriate locations simultaneously.
Solution Approach 2:
The system combines rigid load-resistant units with flexible articulation mechanisms to create a composite protective structure. The rigid units provide mechanical strength and protection capability, while the flexible connections between units enable range of motion and adaptability. This composite approach integrates both opposing requirements within a single system.
3Adaptability or versatility
If modular units with articulation points are used, then flexibility is improved, but system complexity increases
Solution Approach 1:
The load-resistant units are designed as universal modular components that can be arranged in various configurations to protect different body regions. Each unit serves multiple functions: providing protection, enabling articulation, and maintaining structural integrity. This universality reduces overall system complexity by using standardized components rather than custom-designed parts for each location.
