Solution Overview

Problem

Existing lashing devices for large-caliber weapon barrels require manual intervention for locking and unlocking, which is time-consuming and risky, especially in outdoor combat environments, and involves multiple steps that can be hazardous.

Innovation Solution

A lashing device with an actuating element that can both open and close the lashing pliers and lock them automatically, eliminating the need for manual interlocks and simplifying the process by using a spring-elastic coupling for automatic locking and unlocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual locking and unlocking of lashing pliers is used, then the device structure can be simpler, but the operation time increases and safety decreases due to crew members being outdoors

Engineering Contradiction:
Improvestructure complexityVSAvoidoperation time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent combines the locking function with the actuating element by introducing a locking section that can pivot into a blocking position. The actuating element now serves dual purposes: opening/closing the lashing pliers and locking them in position, eliminating the need for separate manual locking operations and reducing overall operation time

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking section is positioned and configured in advance to automatically engage with the lashing jaws when the actuating element is moved to the locking position. This preliminary arrangement allows the locking action to occur as part of the normal actuating sequence without requiring additional manual intervention

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual locking with safety chains or wires is used, then the locking reliability can be sufficient, but the operation becomes more complex and time-consuming

Engineering Contradiction:
Improvelocking reliabilityVSAvoidoperation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is merged into the actuating element itself through the locking section, eliminating the need for separate safety chains or wire ropes. This integration maintains locking reliability while significantly simplifying the operational procedure to a single actuating motion

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking section automatically engages with the lashing jaws through the mechanism's own motion when the actuating element is moved. The system locks itself without requiring external safety devices or additional manual locking steps, reducing operational complexity while maintaining reliability

Inventive Principle:
Principle #25Self-service

3Reliability

If crew members manually lock lashing pliers outdoors, then the locking can be achieved, but safety risks increase due to exposure during combat missions

Engineering Contradiction:
Improvelocking achievementVSAvoidsafety risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The locking mechanism performs the locking action automatically as part of the actuating sequence. The locking section pivots into the blocking position through the mechanism's own motion, eliminating the need for crew members to manually intervene outdoors and thereby removing the safety risks associated with outdoor manual operations during combat missions

Inventive Principle:
Principle #25Self-service

4Reliability

If multiple work steps for lashing and untightening are used, then the locking can be secure, but the process becomes more time-consuming

Engineering Contradiction:
Improvelocking securityVSAvoidlashing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple functions (opening, closing, and locking) into a single actuating element operation. The locking section is integrated such that moving the actuating element to the locking position simultaneously achieves secure locking, eliminating the need for separate manual locking steps and thereby increasing lashing speed while maintaining security

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking section is pre-positioned and configured to automatically engage when the actuating element is moved. This preliminary arrangement allows the locking action to occur as part of the normal actuating sequence rather than as a separate subsequent step, improving productivity while ensuring secure locking

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution simplifies and safeties the lashing and unlashing processes by allowing single-action operation via the actuating element, reducing manual intervention and operational time while ensuring secure locking and unlocking of the weapon barrel.

Implementation Method 1

The locking section and the actuating section are coupled to one another in a resilient manner. Due to the spring-elastic coupling, the locking section can be moved relative to the actuating section by the force of a spring

Methodology Applied
Scientific EffectSpring force: Spring
