Solution Overview

Problem

The difficulty in mounting optical sights on pistols due to the need for permanent modifications to the slide, which limits versatility and compatibility with different optical sights.

Innovation Solution

An adapter plate system that includes a pistol slide with an adapter interface and a rotatable adapter plate, allowing for easy attachment and detachment of optical sights without requiring further modifications to the pistol slide.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pistol slide is permanently modified to mount an optical sight, then the optical sight can be securely attached, but the pistol cannot be easily adapted to different optical sights and requires further modifications if the user wants to switch sights

Engineering Contradiction:
Improvesecure attachment of optical sightVSAvoidability to switch between different optical sights
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system divides the mounting mechanism into two separate components: a base adapter interface that is permanently attached to the pistol slide, and a removable adapter plate that interfaces with the optical sight. This segmentation allows the optical sight to be securely mounted while enabling easy removal and replacement of different sight configurations without modifying the pistol itself

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter interface acts as an intermediary component between the pistol slide and the optical sight. This intermediate structure provides a standardized connection point that facilitates secure attachment while maintaining the flexibility to exchange different adapter plates for different optical sights, eliminating the need for direct permanent modification of the pistol

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the pistol slide is milled to accommodate an optical sight, then the optical sight can be mounted, but additional modifications are required if the user wants to switch to a new optical sight

Engineering Contradiction:
Improveinitial mounting capabilityVSAvoidnumber of modifications required
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The adapter interface is pre-configured on the pistol slide during initial manufacturing or setup. This preliminary action establishes a standardized mounting foundation that eliminates the need for subsequent modifications when switching optical sights, as all future attachments use the same pre-prepared interface

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adapter interface is designed with universal compatibility to accommodate multiple types of optical sights through different adapter plates. This multi-functional design allows a single pistol configuration to support various sight options, reducing the overall complexity of modifications needed across different sight switching scenarios

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

3Stability of the object's composition

If the pistol is not suitable for further modification, then no additional changes can be made to the pistol, but optical sights still need to be mounted or switched

Engineering Contradiction:
Improvepistol structure integrityVSAvoidability to mount or switch optical sights
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting functionality is extracted from the pistol body itself and placed into separate, removable adapter plates. This extraction allows the pistol to remain unmodified and structurally intact while still enabling optical sight attachment and switching through the external adapter mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The adapter interface serves as a mediator that bridges the gap between the unmodified pistol and the optical sight requirements. By introducing this intermediate component, the system enables sight mounting and switching capabilities without compromising the pistol's original structure or requiring additional modifications

Inventive Principle:
Principle #24Intermediary (Mediator)
