Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground detection systems in military vehicles are ergonomically challenging and require significant force to operate, with long tubes limiting ergonomic operation and necessitating the arrangement in a spacious rear area for effective tracking.
Innovation Solution
The detection probe is guided through the vehicle's floor, allowing for shorter lowering paths and improved ergonomics, with a leveraged handle mechanism for easier force application and a one-hand pull lever for ergonomic operation, along with a support bearing device for alignment and locking mechanisms to facilitate precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detection probe is guided through a long tube from the rear wall, then the detection can be performed from inside the vehicle, but the operation becomes ergonomically difficult and requires great force
Solution Approach 1:
Instead of guiding the detection probe through the rear wall from inside the vehicle, the invention inverts the approach by guiding the probe through the floor from below. This allows the operator to work from inside the vehicle while the probe extends downward, reversing the traditional configuration and improving ergonomics by reducing the required tube length and force application.
Solution Approach 2:
The invention changes the spatial dimension through which the detection probe is introduced. Rather than extending horizontally or at an angle through the rear wall, the probe is guided vertically through the floor, utilizing the vertical dimension to achieve shorter path lengths and better operational characteristics.
2Ease of operation
If the detection probe is guided through the floor, then ergonomics are improved and lowering paths are shortened, but the structural complexity increases
Solution Approach 1:
The handle mechanism is divided into functional segments: a lever component for force application, a pivot joint for motion conversion, and a coupling mechanism for connecting to the detection probe. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The handle incorporates a pivot joint that enables dynamic motion conversion, transforming the operator's manual input into the vertical lowering motion required for ground contact. This dynamic element provides mechanical advantage while maintaining structural simplicity.
