Solution Overview

Problem

Existing solutions for reducing recoiling forces on weapon components like sights and range finders often result in uncontrolled absorption of forces, leading to angled barrels, weakened structures, and potential damage to sensitive components, which can affect shooting accuracy and projectile trajectory.

Innovation Solution

A holding device with a shaft or rail allows components to slide relative to the barrel, displacing them before recoiling forces are absorbed, minimizing the impact on the barrel and ensuring the components do not absorb substantial forces until the projectile has left the barrel, using a braking unit with resilient members like springs to absorb forces after the projectile has exited.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If components are fixedly arranged on the barrel, then the components are stable and supported, but the components absorb recoiling forces causing barrel angulation, structural weakening, and trajectory modification

Engineering Contradiction:
Improvecomponent stabilityVSAvoidshooting accuracy
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The holding device transitions from a static fixed arrangement to a dynamic system where the component can move relative to the barrel during firing. The component is initially fixed in a first position, then moves to a second position during recoil, allowing the system to adapt to changing force conditions while maintaining stability when needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The component is pre-positioned in a first position where it does not absorb recoiling forces during the critical phase when the projectile is in the barrel. This preliminary positioning ensures accurate trajectory before the component engages to absorb forces after firing

Inventive Principle:
Principle #10Preliminary action

2Strength

If components are fixedly arranged on the barrel, then the components are securely supported, but the glue lines and structural parts are weakened by transferred loads

Engineering Contradiction:
Improvecomponent support strengthVSAvoidstructural integrity
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The holding device uses a dynamic connection that transitions from an engaged state (providing support) to a disengaged state (avoiding force transfer). The component can move along the holding device, changing from a supported position to a free-moving position, thereby protecting structural integrity while maintaining support when needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The holding device acts as an intermediary between the barrel and the component. It provides support through the first and second positions while controlling the interaction between recoiling forces and the component, preventing direct force transfer that would weaken glue lines and structural parts

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If components immediately absorb recoiling forces, then the components are protected from damage, but the projectile trajectory is influenced reducing shooting accuracy

Engineering Contradiction:
Improvecomponent protectionVSAvoidtrajectory accuracy
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The component is pre-positioned in a first position where it does not absorb recoiling forces during the critical phase when the projectile is in the barrel. This preliminary positioning ensures accurate trajectory before the component engages to absorb forces after firing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The holding device enables periodic engagement and disengagement of the component relative to the barrel. The component disengages during firing (trajectory-critical phase) and engages after firing (recoil-absorption phase), creating a periodic action that separates the conflicting requirements of accuracy and protection

Inventive Principle:
Principle #19Periodic action
