Configurable Handgrip Using Stackable Plates and Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard factory-supplied firearm handgrips often lack customizable ergonomic features, leading to discomfort for users with hands of varying sizes, as the fixed features do not precisely match individual hand shapes or sizes.
Innovation Solution
A configurable handgrip system comprising a stack of alternating plates that can be slid and clamped into a customized shape using an elongated member with a clamp mechanism, allowing users to create personalized ergonomic features like finger ridges and palm swells by adjusting the plate positions and securing them with a threaded system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard factory-supplied handgrip with fixed ergonomic features is used, then manufacturing simplicity is maintained, but adaptability to different hand sizes and shapes deteriorates
Solution Approach 1:
The handgrip is divided into multiple plates (first plate, second plate, third plate, fourth plate) that can be independently positioned and clamped. Each plate can be adjusted to create customized ergonomic features such as finger ridges and palm swells at different locations, allowing the handgrip to adapt to various hand sizes and shapes while maintaining a relatively simple overall structure.
Solution Approach 2:
The handgrip incorporates a dynamic clamp mechanism that allows the plates to be adjusted and repositioned during use. The clamp element can transition between clamped and unclamped states, enabling users to modify the ergonomic features according to their hand dimensions and preferences, thereby improving adaptability without permanently complicating the structure.
2Adaptability or versatility
If adjustable plate positions are implemented, then customization of ergonomic features is improved, but ease of manufacture deteriorates
Solution Approach 1:
By segmenting the handgrip into multiple standardized plates with identical apertures and contact edges, the manufacturing process remains relatively simple. Each plate can be produced using the same mold and assembly procedure, reducing manufacturing complexity while enabling extensive customization through different plate arrangements and positions.
Solution Approach 2:
The plates are designed with universal features including identical apertures for the clamp element and standardized contact edges that can function in multiple positions. This universality allows the same plate design to be used in various configurations, maintaining ease of manufacture while achieving high customization capability through different组合 and positioning.
3Stability of the object's composition
If clamp mechanism is added to secure plates, then stability of plate position is improved, but device complexity increases
Solution Approach 1:
The clamp element is integrated into the existing plate structure rather than being a separate complex mechanism. The clamp element utilizes the plate apertures and contact edges to achieve clamping function, merging the stabilization function with the structural components already present in the handgrip, thereby minimizing additional complexity.
Solution Approach 2:
The clamp mechanism is designed to be self-adjusting and self-securing through the interaction of the clamp element with the plate apertures and contact edges. The mechanical interaction naturally provides stable positioning without requiring external adjustment mechanisms or complex control systems, maintaining simplicity while achieving stability.

AI summary
A configurable handgrip has a plurality of plates, the plates being arranged in a stack, a clamp element operably engaging the stack, and the clamp element being operable to transition between a first released position in which the plates are free to move with respect to each other, and a second clamped position in which the plates are secured against movement with respect to each other, such that the stack may be formed into a selected shape when the clamp is in the released position, and the plates are held in the selected shape when the clamp is in the clamped position. Each plate may define a plate aperture. The clamp element may be an elongated member received in the plate apertures. The plates may each have a contact edge and an opposed recessed edge.
