Handgun Foregrip Segmentation for Accessory Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Senior citizens and disabled individuals face challenges in controlling and using handguns due to lack of finger dexterity, muscle strength, and vision skills, and existing handgun-laser combinations are difficult to control, especially when trying to aim both the handgun and laser from a single grip.
Innovation Solution
A handgun device with a Finger Rest Area and a Rail situated forward of the trigger guard, allowing for separate control of the shooting action with one hand and accessory control, such as a laser, with the non-shooting hand, featuring Finger Stops, a Receiving Tube, ventilation holes, and attachments for accessories like cameras or flashlights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional handgun grip is used, then the handgun can be controlled with one hand, but it is difficult for senior citizens and disabled individuals to control and aim due to lack of finger dexterity, muscle strength, and vision skills
Solution Approach 1:
The handgun control system is segmented into two separate hand control zones: the shooting hand controls the trigger and grip, while the non-shooting hand controls the laser sight and accessories mounted on the foregrip. This segmentation allows each hand to perform specialized functions, making the system more accessible to users with limited dexterity in one hand while maintaining overall control reliability
Solution Approach 2:
A foregrip assembly serves as an intermediary structure between the handgun barrel and the user's non-shooting hand. This foregrip provides a stable mounting platform for laser sights and accessories, and includes ergonomic features like finger rests and finger stops that mediate the interaction between the user's fingers and the control mechanisms, reducing the physical effort and dexterity required
2Adaptability or versatility
If a handgun-laser combination is used from a single grip, then accessory functionality is added, but control and aiming become more difficult
Solution Approach 1:
The control functions are segmented between two hands: the shooting hand maintains control of the handgun trigger and grip, while the non-shooting hand operates the laser sight and accessories mounted on the foregrip. This spatial segmentation of control functions allows both the handgun and laser to be controlled simultaneously without interfering with each other, maintaining ease of operation while adding accessory versatility
Solution Approach 2:
The laser sight and accessories are mounted in a different spatial dimension (on the foregrip along the barrel axis) rather than on the traditional pistol grip. This dimensional relocation creates separate control zones along the length of the handgun, allowing independent operation of the laser and shooting functions without cluttering the primary grip area
3Ease of operation
If the finger rest area is positioned for easy access, then accessory control is improved, but the finger may interfere with the shooting action
Solution Approach 1:
The foregrip is designed with localized functional zones: a finger rest area with specific texture and contour for accessory control, finger stops positioned at precise locations to define the rearward limit of finger travel, and clear spacing from the trigger guard. These local quality variations ensure that fingers can easily access and control accessories while the finger stops and spatial arrangement prevent interference with the trigger pulling motion
Solution Approach 2:
Finger stops are positioned on the foregrip to preemptively prevent the fingers from traveling too far rearward toward the trigger guard. These mechanical stops provide preliminary anti-action by physically blocking the fingers before they can interfere with the shooting action, ensuring reliable trigger control while maintaining easy access to accessory controls
