Angled Barrel Pepper Spray with Conical Orifice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-lethal pepper spray weapons are optimized for maximum range and have a narrow spray angle, which often misses the attacker's face, and lack mechanisms to prevent accidental discharge when stored.
Innovation Solution
A non-lethal weapon design with a rotatable barrel angled upward and a wide conical orifice for increased chances of hitting the attacker's face, combined with a safety mechanism and guard to prevent accidental discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the spray angle is increased to widen the coverage area, then the likelihood of hitting the attacker's face is improved, but the range of the weapon is reduced
Solution Approach 1:
The patent introduces a new dimension by angling the barrel upward at a substantial angle (e.g., 45 degrees) relative to the housing. This dimensional change allows the spray to cover a wider area in the vertical dimension while maintaining effective horizontal range, resolving the contradiction between coverage area and range.
2Loss of time
If the trigger mechanism is made easily accessible for quick response, then the response time is reduced, but the risk of accidental discharge is increased
Solution Approach 1:
The safety mechanism is designed to be engaged by default (preliminary action) and must be deliberately disengaged before the trigger can be pulled. This preliminary blocking action prevents accidental discharge while maintaining quick response capability, as the user only needs to move the safety switch and pull the trigger in sequence.
3Device complexity
If the barrel is fixed in position for structural simplicity, then the device complexity is reduced, but the ability to adjust spray direction is limited
Solution Approach 1:
The patent makes the barrel dynamic by allowing it to rotate within the housing while maintaining a locked position during firing. This rotational capability provides adaptability for adjusting spray direction without requiring complex mounting structures, resolving the contradiction between device complexity and versatility.
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
Effectively neutralizes attackers by spraying pepper extract on the face at close range while preventing accidental pepper spray discharge during storage or use.
Implementation Method 1
The barrel may be adapted to hold a canister of the pepper extract under pressure

AI summary
Non-lethal weapon includes a housing, a barrel insertable into the housing and a barrel locking mechanism. The non-lethal weapon may be adapted for spraying a pepper extract onto a potential attacker in order to disable the potential attacker. The barrel is adapted to hold a canister of the pepper extract under pressure. The barrel may be rotatable to lock the barrel into the housing. A longitudinal axis of the barrel is angled upward at a substantial angle relative to the longitudinal axis of the housing or relative to the upper surface of the housing when the weapon is used. The non-lethal weapon includes a conical orifice adapted to spray the pepper extract over an opening angle of between 70 and 120 degrees.
