Solution Overview

Problem

Existing firearm handgrips lack versatility in controlling both weapon-mounted accessory devices and flashlight devices efficiently, often requiring multiple configurations and attachments.

Innovation Solution

A combination weapon handgrip and accessory controller featuring an elongate grip base with a fastener for attachment to a firearm, an elongate grip sleeve with a keypad for controlling electronic devices, and a dual cable configuration for managing both accessory devices and flashlight devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single cable configuration is used for controlling weapon-mounted accessory devices, then the device complexity is reduced, but the versatility in controlling both accessory devices and flashlight devices is limited

Engineering Contradiction:

Improveversatility in controlling accessory devices and flashlight devicesVSAvoidcable configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handgrip apparatus is designed with a universal control system that can operate both weapon-mounted accessory devices and flashlight devices through a single integrated configuration. The grip sleeve with keypad and connector assembly provides multi-functional control capability, allowing the same device to interface with different types of accessories without requiring separate control mechanisms for each device type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple configurations and attachments are used for controlling different devices, then the versatility is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvecontrol capability for different devicesVSAvoidconvenience of configuration and attachment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention merges the control functions for accessory devices and flashlight devices into a single integrated handgrip apparatus. The grip sleeve, keypad, and connector assembly are combined into one unit that can control multiple device types, eliminating the need for separate attachments and configurations for different accessories.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handgrip apparatus incorporates a rotatable grip sleeve that can be rotated to different angular positions to engage with different device interfaces. This dynamic adjustment capability allows the single apparatus to adapt to different device configurations while maintaining ease of operation through simple rotational movement rather than complex assembly changes.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the grip sleeve is fixed in a single rotational position, then the manufacturing precision is simplified, but the adaptability to different user preferences and device orientations is reduced

Engineering Contradiction:

Improveadjustability to user preferencesVSAvoidrotational positioning mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grip sleeve and grip base incorporate asymmetric engagement features with specific geometric profiles that allow the grip sleeve to rotate and lock into different angular positions. The asymmetric shape profile includes engagement surfaces that mate with corresponding surfaces on the grip base, enabling discrete rotational positioning while maintaining secure engagement at each position.

Inventive Principle:

Principle #4Asymmetry
