Problem

Conventional apparatuses for mounting accessory devices on firearms are complex, prone to failure, and difficult to install and service, especially in harsh environments, posing risks in military or police operations.

Innovation Solution

A rail mountable device with a housing and rail clamp featuring a screw receptacle and screw with ramp members that lock together upon rotation, allowing for secure mounting and easy servicing, along with a removable battery pack and user-operable switches for operational control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional mounting apparatuses are used, then the accessory device can be securely mounted, but the mounting system becomes complex with many moving parts that are prone to failure

Engineering Contradiction:
Improvemounting reliabilityVSAvoidmounting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into distinct functional components: a clamp body with opposing jaws for securing the accessory, a separate screw mechanism for actuation, and ramp members for force transmission. This segmentation allows each component to be optimized independently while reducing overall complexity compared to integrated conventional designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The screw mechanism is extracted as a separate, removable component from the mounting system. This allows the screw to be easily removed and replaced without disassembling the entire mounting apparatus, simplifying maintenance and reducing the complexity of the overall system while maintaining secure mounting capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If conventional mounting apparatuses are used, then the accessory device can be securely mounted, but installation and servicing become difficult and time-consuming

Engineering Contradiction:
Improvemounting securityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The ramp members are pre-configured in the clamp body with their inclined surfaces positioned to automatically engage with the screw mechanism. This preliminary arrangement eliminates the need for complex alignment procedures during installation, allowing the user to simply insert the accessory and tighten the screw for immediate secure mounting.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting system incorporates dynamic elements including the movable screw mechanism that can be easily inserted and removed, and the ramp members that convert rotational screw motion into linear clamping force. This dynamic design allows for quick installation and servicing operations while maintaining secure mounting when engaged.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the accessory device is firmly secured to withstand harsh environments, then mounting reliability improves, but the device becomes difficult to service when left secured to the firearm

Engineering Contradiction:
Improvemounting durabilityVSAvoidservicing ease
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The mounting system is segmented into a permanent clamp body that remains attached to the firearm and a removable screw mechanism. This segmentation allows the clamp body to be firmly secured to withstand harsh environments while the screw can be easily removed for servicing the accessory device without removing the entire mounting apparatus.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The screw mechanism is extracted as a removable component that can be taken out for servicing while the clamp body remains firmly secured to the firearm. This extraction principle enables easy maintenance and replacement of the accessory device while maintaining the durability and security of the mounted connection.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If a simple mounting mechanism is used, then ease of installation improves, but the mounting system becomes bulky and heavy affecting firearm aiming

Engineering Contradiction:
Improveinstallation simplicityVSAvoidmounting system weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The mounting system is segmented into compact components including a small clamp body and a slender screw mechanism. This segmentation allows for a lightweight design that minimizes impact on firearm balance and aiming while maintaining simple installation through the modular structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dynamic screw mechanism provides a simple rotational-to-linear motion conversion that achieves secure mounting with minimal mechanical elements. This dynamic approach eliminates the need for bulky static fastening structures, reducing weight while maintaining installation simplicity.

Inventive Principle:
Principle #15Dynamics
