Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing less-lethal electronic discharge devices, such as stun guns and batons, often fail to maintain a safe distance from unruly individuals, lack durability in mass crowd scenarios, and provide inadequate warning mechanisms before delivering a high voltage shock, posing risks to both security personnel and the public.
Innovation Solution
An extendable electronic discharge staff that can be held in both hands, adjustable in length, and capable of delivering varying voltage levels, with a visible snapping arc and multiple warning stages before incapacitating shock, allowing for momentary or prolonged activation, and featuring a rechargeable battery pack for extended use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional high voltage self defense devices are used with electrodes close to the operator's hand, then the device can deliver effective high voltage shock, but the operator cannot maintain a safe distance from unruly individuals
Solution Approach 1:
The device employs a telescoping mechanism where multiple rod sections are nested within each other, allowing the staff to extend to a long operational length while remaining compact when retracted. This enables the operator to maintain a safe distance from unruly individuals while carrying the device in a convenient, space-saving manner.
Solution Approach 2:
The staff transitions from a static, fixed-length design to a dynamic, adjustable-length structure. The telescoping sections can be extended or retracted based on operational needs, allowing the operator to adapt the device length to maintain optimal safety distance while preserving maneuverability when needed.
2Ease of operation
If conventional stun guns deliver immediate high voltage shock, then the device can incapacitate individuals quickly, but it lacks warning mechanisms that could de-escalate situations
Solution Approach 1:
The device incorporates a visible arc indicator that activates before high voltage shock delivery. This preliminary visual warning allows the operator to communicate intent to the individual, providing an opportunity for de-escalation before the harmful high voltage shock is delivered, thus reducing unnecessary injury.
Solution Approach 2:
The visible arc serves as immediate visual feedback to the individual that the device is activated and ready to deliver shock. This feedback mechanism enhances operator control by making the device state transparent, allowing for controlled escalation only when necessary while providing clear warning to prevent unnecessary use.
3Ease of operation
If single-hand operated stun guns are used, then the device is portable and easy to deploy, but it lacks the stability and control needed in mass crowd scenarios
Solution Approach 1:
The staff is divided into multiple telescoping sections that can be independently managed, allowing the operator to extend the full length with both hands for stability in crowd control scenarios, or retract to a more manageable size for portability when needed.
Solution Approach 2:
The device transitions from a compact, single-handed grip configuration to an extended, two-handed staff configuration by utilizing the length dimension. This dimensional transformation provides the stability and control needed for mass crowd scenarios while maintaining portability through retraction.
4Adaptability or versatility
If fixed length staffs are used, then the device structure is simple and reliable, but it cannot adapt to different operational distances and scenarios
Solution Approach 1:
Multiple staff sections are nested within each other in a telescoping arrangement, providing adjustable length capability while minimizing the device footprint when retracted. This nesting approach delivers adaptability for different operational distances without excessive complexity in the overall structure.
Solution Approach 2:
The staff evolves from a static, fixed-length design to a dynamic, adjustable-length structure that can be extended or retracted based on operational requirements. This dynamic capability provides versatility for different scenarios while using proven telescoping mechanisms that balance complexity with reliability.

AI summary
An extendable electronic discharge staff will consist of a central sliding member translating within a tubular body member to be positioned by the means of a spring-loaded ball detent. When the central sliding member is positioned, it will be locked in place by the means of a locking nut at the distal end of the tubular body member. A forward adjustable handgrip will be located and locked into position along the length of the tubular body member to accommodate the size and comfort of the person using the device. By rotating the rear hand grip, the device will be turned on or off, and by sliding the rear handgrip forward or backward a high or low voltage will be delivered to the distal contact end of the central sliding member. On an alternate embodiment having three contact positions, the default center position delivers low voltage while both forward and backward outer positions deliver high voltage. This action gives the operator two different voltage capabilities along with a visible snapping arc to indicate the potential of the device. A sealed cylindrical housing fixed to the rear of the tubular body member will house a removable battery pack and electronic control module. The device is capable of giving a momentary delivery, a prolonged delivery, or several prolonged deliveries and has been designed not to stun an individual unless necessary, giving the unruly individual several warnings in advance.
