Solution Overview
Problem
There is a risk of objects falling from substantial heights during construction or outdoor maintenance, leading to potential damage from impact, and existing solutions fail to effectively protect objects that cannot be moved.
Innovation Solution
A protective guard system comprising adjustable panel assemblies and a top plate that can withstand significant impacts, allowing for flexible positioning and expansion to cover various objects, made from rigid materials like aluminum with optional flexible top sheets for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective guard system is designed to withstand significant impacts from falling objects, then the protection reliability is improved, but the device complexity increases due to adjustable panel assemblies and rigid material construction
Solution Approach 1:
The protective guard system is divided into multiple panel assemblies that can be independently positioned and adjusted. Each panel assembly includes individual panels that can be selectively moved to different locations, allowing the system to protect various objects while maintaining manageable complexity through modular design
Solution Approach 2:
The panel assemblies are designed with movable and adjustable components that allow dynamic reconfiguration of the guard system. Panels can be selectively positioned at different locations and angles to adapt to various protection needs, providing both reliability and flexibility without requiring a completely new system for each scenario
2Strength
If the guard system uses rigid materials like aluminum for impact resistance, then the strength is improved, but the weight of the stationary object increases
Solution Approach 1:
The guard system utilizes aluminum material that provides high strength-to-weight ratio for impact resistance. The rigid aluminum construction withstands significant forces from falling objects while the material's inherent lightweight properties help mitigate the weight increase issue, achieving both strength and relative lightness
3Adaptability or versatility
If the guard system provides adjustable coverage for various objects, then the adaptability is improved, but the device complexity increases due to multiple panel assemblies
Solution Approach 1:
The panel assemblies are designed as universal components that can protect multiple different types of objects through selective positioning and configuration. The same panel assembly structure can be adapted to protect various objects by adjusting panel locations and orientations, providing multi-functionality without requiring entirely separate systems for each application
Solution Approach 2:
The system uses segmented panel assemblies that can be independently configured to match different protection scenarios. This segmentation allows flexible adaptation to various object shapes and sizes while keeping each individual panel assembly relatively simple in design
