Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a reliable and compact method to detect and indicate impacts or acceleration events during the manufacturing, storage, and transportation of sensitive or fragile objects, as existing solutions fail to provide effective visual feedback on exposure to such events.
Innovation Solution
A device comprising a tube with two fluids of different viscosities, where a change in color occurs when a predetermined level of impact is detected, allowing for visual indication of the impact through the mixing of the fluids, enabling passive and compact impact detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing impact detection solutions are used, then impact detection capability is provided, but the devices are complex and require electrical integration
Solution Approach 1:
The patent replaces complex electrical impact detection systems with a simple mechanical/fluid-based indicator system. The device uses a tube containing multiple fluids with different viscosities and colors, where impact forces cause the fluids to mix and produce a visible color change, eliminating the need for electronics while maintaining reliable impact detection capability.
Solution Approach 2:
The impact indicator is designed as a passive, self-activating device that automatically detects and indicates impact events without requiring external power sources, control systems, or electrical integration. The fluid mixture responds autonomously to impact forces, providing reliable detection through self-service operation.
2Volume of moving object
If traditional impact indicators are used, then visual indication is provided, but the devices are not compact and cannot be easily integrated
Solution Approach 1:
The patent creates a compact impact indicator by nesting multiple functional elements within a single small tube. The tube contains multiple layered fluids (different colors and viscosities) along with optional elements like separating barriers or mixing elements, all confined within a compact cylindrical volume that can be easily integrated into various products.
Solution Approach 2:
The patent combines multiple functions into a single integrated device: the tube serves as both the container and the indicator medium, the fluids provide both the sensing mechanism and the visual indication, and optional elements like magnets or barriers serve multiple purposes (separation, mixing control, and indication). This merging creates a compact, easily integratable device.
3Adaptability or versatility
If fluid mixing is used for impact indication, then visual feedback is provided, but the sensitivity adjustment is limited
Solution Approach 1:
The patent enables sensitivity adjustment by varying physical parameters of the fluids and tube configuration without increasing device complexity. Sensitivity can be modified by changing fluid viscosities, densities, or volumes, adjusting the size or position of separating barriers, or modifying the tube dimensions. These parameter changes allow the same simple device structure to adapt to different impact detection thresholds.

AI summary
A device and technique for impact detection includes a tube having a first fluid and a second fluid disposed therein, wherein a viscosity of the second fluid is greater than a viscosity of the first fluid, and wherein, responsive to a predetermined level of impact received by the impact indicator, at least a portion of the first fluid mixes into the second fluid to create a change in color of the second fluid to provide a visual indication of the received impact.
