Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic stun grenades face challenges with size and weight constraints due to the need for large and heavy power sources, which limits their performance and operational time, and requires additional burden on users, especially when used in applications like grenade launchers.
Innovation Solution
The electronic stun grenade design features a light-generating component mounted on the exterior surface of the casing, allowing for increased internal volume for power storage and external wiring, utilizing a series-parallel LED configuration and a high voltage lithium battery, with a heat conductive casing and microcontroller for control, enabling omnidirectional light emission and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the means for generating light is mounted inside the casing, then the structure is compact and protected, but the internal volume available for power supply is limited
Solution Approach 1:
The light-generating means is relocated from the internal three-dimensional space to the external surface of the casing, effectively utilizing the surface dimension. This dimensional transition frees up the entire internal volume for power supply while maintaining structural integrity and protection through the casing.
Solution Approach 2:
The light-generating means and its associated wiring are extracted from the internal volume of the casing and mounted on the external surface. This extraction eliminates the spatial conflict between light-generating components and power supply, allowing maximum internal volume utilization.
2Quantity of substance
If the casing size is increased to accommodate a larger power supply, then the power storage capacity increases, but the weight of the stun grenade increases
Solution Approach 1:
By moving the light-generating means to the external surface, the design maximizes the use of internal volume for power supply without increasing the external dimensions of the casing. This allows greater power storage capacity to be achieved within the same footprint, avoiding additional weight from a larger casing.
3Volume of stationary object
If the internal volume is reduced to decrease size, then the stun grenade becomes more compact, but the power storage capacity is reduced
Solution Approach 1:
The invention maintains a compact overall size by keeping the casing dimensions small while achieving large power storage capacity by utilizing the external surface for light generation. This effectively decouples the relationship between internal volume and power capacity, allowing maximum power density within a compact form factor.
