Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency response devices lack a comprehensive 'flash-bang' effect, failing to provide both intense light and sound distraction, and often do not include sound components, which are essential for effectively disorienting perpetrators.
Innovation Solution
An LED light and sound ball activated upon impact, featuring a clear polymeric casing with a circuit board and rig rods that trigger LEDs and a sound generator, producing up to 2700 lumens of light and 110-129 dB of unique siren tones, capable of being fired from a launcher and rechargeable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing emergency response devices use only light emission, then the device structure remains simple, but the distraction and disorientation effect is insufficient without sound
Solution Approach 1:
The patent combines light emission (LEDs) and sound generation (speaker with siren tones) into a single integrated emergency response device. The housing contains both optical components (LEDs with reflectors) and acoustic components (speaker, amplifier, microphone) that work together to create a comprehensive distraction effect, resolving the contradiction between effectiveness and complexity by merging multiple functions into one unified device.
Solution Approach 2:
The device performs multiple functions simultaneously: it emits intense light through LEDs, generates distinctive siren sounds through the speaker, and can detect ambient sound through the microphone. This multi-functionality enhances the distraction and disorientation effect while maintaining a single device structure, addressing the need for comprehensive emergency response capabilities.
2Object-affected harmful factors
If the device emits both intense light and loud sound simultaneously, then the flash-bang effect is achieved, but the energy consumption increases
Solution Approach 1:
The device employs periodic flashing of LEDs and intermittent siren tone emission rather than continuous operation. The control circuit can activate LEDs in flashing patterns and the speaker in periodic intervals, creating the necessary flash-bang effect while reducing overall energy consumption compared to continuous light and sound emission.
Solution Approach 2:
The device uses high-lumen LEDs (900 lumens each) that provide intense light output with lower power consumption compared to traditional lighting. The sound generator produces up to 129 dB siren tones efficiently. These parameter optimizations allow the device to achieve the flash-bang effect with reduced energy requirements.
3Illumination intensity
If the device uses high-lumen LEDs to illuminate the area, then the illumination intensity is sufficient, but the device size and weight increase
Solution Approach 1:
The patent replaces traditional mechanical lighting systems with LED technology. The LEDs provide 900 lumens each (2700+ lumens total) with significantly lower weight and power consumption compared to incandescent or halogen alternatives. This substitution maintains sufficient illumination intensity while reducing the overall device weight for easier handling by emergency responders.
4Length of moving object
If the device includes a launcher mechanism for greater range, then the deployment range increases, but the device complexity and launch preparation time increase
Solution Approach 1:
The system is divided into two separate components: the light and sound ball device, and the launcher. The launcher (separate device) provides the propulsion mechanism using compressed air or CO2 cartridges, while the ball contains only the electronic components (LEDs, speaker, battery, control circuit). This segmentation allows the ball to remain relatively simple while achieving greater deployment range through the dedicated launch mechanism.

Function Achieved in This Case
The device effectively illuminates and disorients an area with intense light and distinctive sound, providing a 'flash-bang' effect similar to explosive devices, enhancing the ability of emergency responders to distract or tag perpetrators.
Implementation Method 1
connect a positive terminal of an internal battery (or batteries) to a plurality of light emitting diodes (LEDs)
Implementation Method 2
The LEDs can, for example, provide 900 lumens per light or more, equaling 2700 lumens or more in total
Implementation Method 3
The sound generator includes a microprocessor, a power amplifier and a speaker or other sound transducer capable of generating, for example, up to 110 to 129 dB of unique siren tones
Implementation Method 4
The outer casing may be in two hemispherical pieces that are fused together to house the remaining components therein

AI summary
The LED light and sound ball for emergency responders is activated upon contact after being fired from a launcher to illuminate and direct responders to an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical outer casing, and a rectangular, clear inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to continuously illuminate a plurality of bright LEDs and continuously activate a sound generator that emits a foghorn-type alarm. The LED light and sound ball may be thrown or fired from a conventional compressed air launcher.
