Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical acceleration sensing devices lack effective visual indicators to detect excessive forces, which can lead to undetected potential head trauma in athletes or damage to shipping materials.
Innovation Solution
A force sensor with a hollow container, magnetic members, and a marking device that engages the container walls upon exceeding a predetermined force, providing a visual indication through a dye or ink distribution mechanism, allowing for attachment to mouthguards or shipping containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mechanical acceleration sensor is used to detect excessive forces, then force detection capability is provided, but visual indication of excessive force is not achieved
Solution Approach 1:
The patent employs a marking device that distributes dye or ink to create a visual color change indication when excessive force is detected. The marking device includes a marking surface with dye distributed thereon, which transfers the dye to a receiving surface upon engagement, providing clear visual information about the detected force event.
Solution Approach 2:
The patent introduces a marking device as an intermediary between the magnetic members and the visual indication system. When the second magnetic member engages the container wall, the marking device on the second magnetic member transfers dye to the wall, serving as a mediator that converts mechanical movement into visible information.
2Force
If magnetic members are used to detect force, then force sensing is achieved, but visual marking capability is not provided
Solution Approach 1:
The patent merges the force sensing function of the magnetic members with the visual marking function of the marking device. The marking device is disposed on the second magnetic member, combining two functions (force detection and visual indication) into a single integrated system that operates through the same mechanical engagement mechanism.
3Loss of information
If a marking device with dye distribution is used, then visual indication is achieved, but device complexity increases
Solution Approach 1:
The marking device operates through self-service mechanisms where the dye distribution and transfer occur automatically through capillary action and surface tension. The marking surface allows dye to migrate and transfer to the receiving surface without requiring additional power sources, control systems, or complex actuation mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sensor effectively indicates excessive forces with a visual marker, prompting medical examination for athletes or identifying potential damage to shipping materials, enhancing safety and logistics by providing a clear, visible sign of force exceeding a set threshold.
Implementation Method 1
a second magnetic member magnetically attracted to the first magnetic member
Implementation Method 2
the marking device engages one of the plurality of walls and wherein the marking device marks the one of the plurality of walls
