Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional weapon accessory mounts are used, then accessories can be mounted to weapons, but the design becomes complex with multiple moving parts requiring additional maintenance and tools

Engineering Contradiction:
Improveaccessory mounting capabilityVSAvoidmount design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mount is divided into distinct functional segments: a base portion that interfaces with the weapon, an accessory portion that interfaces with the accessory, and a alignment pin mechanism. This segmentation allows each part to perform its specific function independently, reducing overall complexity while maintaining versatility

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mount design incorporates a universal interface capability where the base portion with alignment pin can work with various weapon types, and the accessory rail can accommodate multiple accessory types, achieving multi-functionality without requiring complex adjustment mechanisms

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

2Reliability

If conventional weapon accessory mounts are used, then accessories can be securely mounted, but additional tools and maintenance are required

Engineering Contradiction:
Improveattachment securityVSAvoidmaintenance requirement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The alignment pin mechanism is designed to be self-aligning and self-locking, where the pin automatically guides the accessory into proper alignment and secures it without requiring additional tools or complex locking mechanisms, making the system self-sufficient and easy to maintain

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If conventional weapon accessory mounts are used, then accessories can be mounted, but the operator must carry additional weight and tools

Engineering Contradiction:
Improveaccessory adaptation capabilityVSAvoidoperator carried weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The design extracts and eliminates unnecessary components from conventional mounts, keeping only the essential elements (base, accessory rail, alignment pin) required for functionality. This removal of extraneous parts reduces weight while preserving the core adaptation capability

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If conventional weapon accessory mounts are used, then accessories can be secured, but more time is required to secure the mount to the weapon

Engineering Contradiction:
Improvemount securityVSAvoidmounting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The alignment pin is pre-positioned in the base portion, and the accessory rail is pre-configured with mounting grooves, so that when the accessory is brought to the mount, alignment and securing occur automatically without requiring time-consuming adjustment or multiple steps

Inventive Principle:
Principle #10Preliminary action

AI summary

A weapon accessory mount for removably mounting an accessory on a weapon. The weapon accessory mount includes an accessory rail supported by a base with a weapon attachment interface that engages the weapon. The weapon attachment interface includes an alignment pin that interfaces a portion of the weapon and a retaining pin that couples to an additional portion of the weapon. The accessory rail utilizes mounting grooves to interchangeably couple weapon accessories to the weapon accessory mount. Furthermore, accessory interference locators are located within some of the mounting grooves to define weapon-accessory-specific locations along the accessory rail, in which a weapon accessory should not be mounted to. Additionally, the weapon accessory mount is configured for mounting non-boresight aligned optics to a weapon and locating the non-boresight aligned optic in relation to the weapon to use in tracking a target.
