Charging Slide Accessory for Stable Optic Mounting and Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-automatic handguns lack a stable, secure platform for charging and mounting sighting devices, posing difficulties for users with hand ailments and compromising the balance and functionality of the weapon.
Innovation Solution
A charging handle accessory with a sliding connection and serrations that securely attaches to the slide, providing a stable grip and mounting platform for a sighting device, ensuring the sighting device maintains its zero position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charging handle accessory is added to assist users with hand ailments, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The charging handle accessory serves as an intermediary device between the user's hand and the firearm's charging mechanism. It provides a larger, textured gripping surface that mediates the interaction, allowing users with hand ailments to effectively grasp and operate the charging slide without directly handling the original small, smooth charging handle.
Solution Approach 2:
The charging handle accessory is designed as a separate, attachable component that segments the charging function from the main firearm body. This modular approach allows the accessory to be added only when needed, maintaining the simplicity of the base firearm while providing enhanced operation capability when attached.
2Adaptability or versatility
If a sighting device is mounted on the charging accessory, then adaptability is improved, but reliability of mounting security worsens
Solution Approach 1:
The sighting device is mounted on the upper surface of the charging accessory, utilizing the vertical dimension above the gripping area. This dimensional placement provides a stable mounting platform that is elevated above the gripping surfaces, creating a separate functional zone that does not interfere with hand operation while providing secure attachment points for the sighting device.
Solution Approach 2:
The charging accessory serves multiple functions: it provides an enhanced gripping surface for charging operations and simultaneously serves as a mounting platform for sighting devices. This multi-functionality increases adaptability without requiring separate attachment mechanisms, as the same structural body supports both charging and sighting functions.
3Adaptability or versatility
If the accessory structure is enlarged to provide a stable mounting platform, then adaptability is improved, but the handgun balance worsens
Solution Approach 1:
The accessory is designed with a compact, streamlined shape that anticipates the need for mounting a sighting device. The upper surface is prepared in advance with appropriate geometry and attachment features that accommodate various sighting devices without requiring additional structural enlargement, thus maintaining balance while providing mounting capability.
Solution Approach 2:
The accessory employs local quality by concentrating the enlarged, textured gripping surface only where needed for hand contact, while keeping the upper mounting surface relatively compact and smooth. This localized enhancement provides the necessary stability for mounting without unnecessarily enlarging the overall structure and disrupting the handgun's balance.

AI summary
A charging handle accessory (11) has an upper portion (13) with a pair of parallel, spaced-apart sidewalls connected at their upper extent. The upper portion is configured to be assembled over an upper portion of the charging slide (3). A lower portion (15) has a pair of parallel, spaced-apart sidewalls connected at one end. Each of the sidewalls of the lower portion has a lip (19) configured to engage a lower extent of the charging slide. A sliding connection is provided at the lower extent of the upper portion and the upper extent of the lower portion, wherein the upper and lower portions are coupled together in sliding relation. A fastener (37) extends between the upper and lower portions to secure the upper and lower portions against sliding relative to one another and secure them on the charging slide of the firearm.
