Crash Guard Impact Detection for Hidden Damage Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision detection systems are not effectively designed for fixedly erected crash guards, as they fail to detect non-visually apparent damage, leading to potential risks in industrial environments where forklifts are used, and existing solutions are costly and complex when adapted for static structures.
Innovation Solution
A collision detection system that uses sensors to measure acceleration and calculate impact energy, comparing it to threshold values, generating an alarm for impacts above a preset value, and recording crash history to plan preventive maintenance, utilizing a processing unit and algorithms to assess the state of crash guards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crash guard undergoes plastic deformation below the maximum energy level, then the system reacts elastically and returns to its original shape, but non-visually apparent internal damage occurs which reduces initial strength and creates safety risks
Solution Approach 1:
The patent applies a color-changing indicator system that visually signals the state of the crash guard. When the crash guard is subjected to impact forces, indicators change color to display different states (e.g., green for safe, yellow for damaged, red for critical), making internal damage visible without requiring complex sensors or electronic systems.
2Measurement precision
If vehicle-based collision detection systems with multiple position sensors are used to detect impacts, then the three-dimensional image comparison can determine impact location, but the system becomes costly and complex for fixedly erected structures
Solution Approach 1:
The patent extracts only the essential function of impact detection from complex vehicle-based systems. Instead of using multiple position sensors and three-dimensional image processing, it employs a simplified mechanism with mechanical indicators that directly show impact location and severity through color changes, eliminating the need for electronic processing while maintaining detection accuracy.
Solution Approach 2:
The patent uses inexpensive, simple mechanical indicators that can be easily replaced rather than investing in costly, complex electronic sensor systems. The indicators are designed to be low-cost components that provide sufficient information for safety assessment without requiring sophisticated processing equipment.
3Productivity
If forklift drivers cause heavy crashes without reporting them when no visible damage is apparent, then operational continuity is maintained, but the crash guard suffers serious internal damage that creates risks for subsequent crashes
Solution Approach 1:
The patent implements a visual feedback system through color-changing indicators that immediately show the crash guard's state after impact. This provides drivers and operators with clear information about damage levels, enabling them to make informed decisions about whether to continue operations or report the incident, thus maintaining both productivity and safety.
