Solution Overview

Problem

Existing pistols with breech slides and loading aids are inflexible and fail to adapt to individual ergonomic requirements, particularly for shooters with varying hand sizes and gripping forces, leading to difficulties in loading and cocking, especially in pistols without a hammer.

Innovation Solution

A detachable loading aid is designed to be secured below a sighting element, with a mounting base that complements a recess in the breech slide, allowing for tool-free assembly and exchange, and can be adjusted in size and shape to fit different hand anatomies, providing improved grip and ergonomic adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a loading aid is integrated into the breech slide, then the grip surface is increased and loading becomes easier, but the design becomes inflexible and cannot adapt to different hand sizes and gripping forces

Engineering Contradiction:
Improveloading easeVSAvoidadaptability to different hand sizes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The loading aid is divided into a first loading aid portion and a second loading aid portion that can be selectively mounted on the breech slide. This segmentation allows users to choose different configurations based on their hand size and gripping force requirements, resolving the contradiction between ease of operation and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The loading aid portions are designed to be selectively mountable and removable, transforming the static integrated design into a dynamic configurable system. Users can adjust the loading aid configuration based on their individual ergonomic needs, maintaining both ease of operation and adaptability.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a loading aid protrudes from the breech slide to increase grip surface, then loading becomes easier, but the device complexity increases

Engineering Contradiction:
Improvegrip securityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The loading aid is segmented into separate mountable portions rather than a single complex integrated structure. This reduces overall device complexity while maintaining the grip surface enhancement benefit, as users only attach the portions they need.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The breech slide is designed with multiple mounting locations that can accommodate different loading aid portions. This universal mounting system allows the same base structure to serve multiple functions with different loading aid configurations, reducing complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the loading aid is detachably mounted for easy exchange, then adaptability to different users is improved, but the reliability of the mounting connection may be compromised

Engineering Contradiction:
ImproveexchangeabilityVSAvoidmounting reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The mounting connection is designed with localized features such as recesses and protrusions that provide secure mechanical engagement. The local quality of the mounting interface ensures reliable connection while maintaining overall detachability for exchangeability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The mounting system is designed to be self-securing through complementary geometric features that automatically engage when the loading aid portion is installed. This self-service mounting mechanism ensures reliability without requiring additional fastening operations, balancing exchangeability with mounting reliability.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a pistol comprising a breechblock slide (37) and a loading aid (1), which is arranged thereon, protrudes from the outer surface of the breechblock slide (37) in the form of at least one projection (21) and is detachably mounted on the breechblock slide (37), wherein the loading aid (1) of the latter is arranged under a sighting element (71) and is secured against falling out by the base (75) thereof. The invention also relates to a breechblock slide (37) for a pistol that has a substantially U-shaped profile and a loading aid (1) which is detachably mounted on the breechblock slide (37), wherein the loading aid (1) of the latter is arranged underneath a sighting element (71) and is secured against falling out by the base (75) thereof. Finally, the invention relates to a loading aid (1) for a breechblock slide (37), the mounting base (18) of which is formed in such a way as to complement a first recess (39) in the breechblock slide (37).
