Operator Fixation Support for Stable Military Vehicle Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military vehicles experience unpredictable movements during operation, affecting the aiming operation of vehicle operators, leading to muscle fatigue and reduced accuracy.
Innovation Solution
A military vehicle with an aiming operation arrangement that includes a support device with fixation devices operable between non-fixated and fixated states, providing stabilization of one or more body parts of the operator to reduce the influence of vehicle movement, thereby enhancing aiming accuracy and reducing muscle fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator remains unrestrained during vehicle movement, then the operator can maintain freedom of movement and comfort, but the vehicle movement causes muscle fatigue and reduced aiming accuracy
Solution Approach 1:
The restraint system is designed to be dynamically adjustable, allowing the operator to switch between restrained and unrestrained states based on operational needs. The fixation devices can be activated during vehicle movement for stability and deactivated when vehicle movement ceases to maintain operator freedom, resolving the contradiction between aiming accuracy and ease of operation.
Solution Approach 2:
The system changes the physical state of the operator from unrestrained to restrained by activating fixation devices that contact and stabilize specific body parts. This parameter change (from free movement to constrained movement) directly addresses the accuracy problem while being reversible to maintain operational flexibility.
2Measurement precision
If fixation devices are activated to stabilize the operator during vehicle movement, then aiming accuracy is improved, but the device complexity increases
Solution Approach 1:
The restraint system is divided into multiple independent fixation devices, each targeting specific body parts (thighs, torso, head/neck). This segmentation allows the system to achieve comprehensive stabilization through simple, modular components rather than a single complex mechanism, reducing overall system complexity while maintaining effectiveness.
Solution Approach 2:
The fixation devices serve multiple functions: they provide mechanical restraint to reduce vehicle movement influence, distribute forces to prevent injury, and can be independently activated or deactivated. This multi-functionality reduces the need for separate systems for different purposes, thereby reducing overall device complexity.
3Stability of the object's composition
If multiple fixation devices are used to restrain multiple body parts, then the stabilization effect is enhanced, but the ease of operation decreases
Solution Approach 1:
Multiple fixation devices are integrated into a unified restraint system with common control mechanisms. The activation and deactivation of individual fixation devices can be coordinated through a single control interface, allowing the operator to manage multiple restraint points without proportionally increasing operational complexity. This merging maintains simplicity while achieving comprehensive stabilization.
