Solution Overview
Problem
Existing electroshock weapons face issues with safe and efficient use, accidental discharge, and unauthorized use, particularly due to design flaws that make them difficult to carry, activate, and prevent from being taken by attackers.
Innovation Solution
A hand-held personal-protection shock device with a safety-pin mechanism, siren for unauthorized use, ergonomic design for secure grip, built-in recharging, and a switch configuration for safe and rapid activation, along with a removable safety pin to prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device is made small and concealable, then ease of carrying is improved, but the shocking contacts become too close to the user's hand creating a shock risk
Solution Approach 1:
The device is divided into separate functional modules: a handle portion containing controls and a shock delivery portion with contacts. This segmentation allows the contacts to be positioned at an optimal distance from the user's hand while keeping the overall device compact and concealable.
Solution Approach 2:
The shock delivery portion is designed to extend from the handle in a direction away from the user's hand, utilizing spatial dimensionality to resolve the contradiction between compact size and safe contact positioning.
2Object-affected harmful factors
If the device is made bulky to position shocks away from hand, then shock safety is improved, but ease of carrying and handling deteriorates
Solution Approach 1:
By separating the handle and shock delivery portions, the design achieves safe shock positioning without requiring the entire device to be bulky. The handle remains compact for easy carrying while the shock portion extends appropriately.
3Ease of operation
If the device is made easy to activate, then ease of operation in attack is improved, but risk of accidental discharge increases
Solution Approach 1:
The safety pin mechanism extracts the accidental discharge risk by requiring a deliberate action (removing the pin) to enable activation. This separates the easy activation during attack from the safety during carrying.
Solution Approach 2:
The safety pin must be removed in advance before the device can be activated, creating a preliminary safety step that prevents accidental discharge while allowing rapid activation when needed.
4Productivity
If the device requires thrusting toward the attacker, then shock delivery capability is improved, but the device becomes vulnerable to being slapped away or taken
Solution Approach 1:
The safety pin acts as an intermediary mechanism that must be removed to enable activation. This intermediary step ensures the device remains securely in the user's hand during the activation process, preventing it from being easily slapped away or taken.
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 device provides a secure, easy-to-use, and safe personal protection solution that prevents accidental discharge and unauthorized use, ensuring effective deployment while discouraging theft and ensuring the device remains operational only for authorized users.
Implementation Method 1
sends low-voltage from a rechargeable battery to a high-from-low-voltage unit that generates a high-voltage, low-current pulsed output to two conducting shock plates to cause electric arcing or sparking
