Aiming Support Fixation for Stable Military Vehicle Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military vehicles experience unpredictable movements during terrain navigation, affecting the aiming operation of vehicle operators, leading to muscle fatigue and reduced accuracy.
Innovation Solution
A military vehicle equipped with an aiming operation arrangement featuring a support device with fixation devices that can be adjusted between fixated and non-fixated states, providing stabilization for the operator's body parts to reduce the influence of vehicle movement during aiming operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator operates the aiming device during vehicle movement without fixation, then the operator can maintain freedom of movement, but the vehicle movement affects aiming accuracy and causes muscle fatigue
Solution Approach 1:
The fixation device is designed to be dynamically adjustable between fixated and non-fixated states, allowing the operator to switch between stability and freedom of movement based on operational requirements. This dynamic adjustment resolves the contradiction by providing both states as needed rather than being fixed in one condition.
Solution Approach 2:
The system changes the fixation parameter from fixed to variable, allowing the degree of fixation to be adjusted according to the situation. This parameter change enables the operator to optimize between aiming accuracy and movement freedom by selecting the appropriate fixation level for each operational context.
2Duration of action of moving object
If the operator operates the aiming device during vehicle movement without support, then the device structure remains simple, but the operator experiences muscle fatigue and reduced operational duration
Solution Approach 1:
The support device is segmented into modular fixation components that can be independently adjusted and positioned. This segmentation allows the complex function of supporting the operator during vehicle movement to be divided into manageable parts, reducing the perceived complexity while extending operational duration through targeted support.
Solution Approach 2:
The fixation device is designed to be self-adjusting and self-regulating, providing automatic support to the operator without requiring constant external intervention. This self-service capability extends the operational duration by maintaining operator stability autonomously during vehicle movement.
3Stability of the object's composition
If fixation devices are activated during aiming operation, then vehicle movement influence is reduced, but the device complexity increases
Solution Approach 1:
The fixation device is designed with multi-functionality, serving both as a support structure and as a stabilization mechanism. This universal design reduces the need for separate components, thereby maintaining operator stability while minimizing the increase in device complexity through consolidated functionality.
