Vehicle Accessory Mounting Control for Reliable Dismounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted accessory systems require inconvenient and time-consuming dismounting processes that rely on in-cabin controllers, which can malfunction or become disconnected, preventing dismounting when needed.
Innovation Solution
A system with a first controller independent of the in-cabin controller powers actuators to mount or dismount accessories, allowing dismounting without input from the second in-cabin controller, using a toggle switch and independent power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the in-cabin controller is used to control dismounting of the accessory, then centralized control and monitoring are improved, but the reliability of dismounting operation deteriorates when the controller fails or becomes disconnected
Solution Approach 1:
The control system is segmented into two independent parts: a primary in-cabin controller for normal operation and a secondary independent controller mounted on the accessory itself for backup operation. This segmentation ensures that failure of one controller does not prevent dismounting operations.
Solution Approach 2:
The system changes the operational state by switching between controller modes. The independent controller on the accessory can be activated when the in-cabin controller is unavailable, changing the control parameter from centralized to decentralized operation.
2Measurement precision
If the in-cabin controller must be accessed for dismounting, then control precision is improved, but the time required for dismounting operation increases
Solution Approach 1:
The independent controller is pre-mounted on the accessory itself, eliminating the need to return to the in-cabin controller during dismounting. This preliminary positioning of the control interface directly on the accessory saves time by allowing immediate local control.
3Ease of operation
If electrical connection is maintained between the in-cabin controller and accessory during dismounting, then control functionality is improved, but the risk of controller disruption or malfunction affecting dismounting increases
Solution Approach 1:
The control functionality is extracted from the in-cabin controller and placed directly on the accessory through an independent controller. This extraction creates operational independence, allowing the accessory to be controlled and dismounted even when disconnected from the vehicle's electrical system.

AI summary
A system is for mounting or dismounting an accessory, such as a snow plow, from a vehicle. The system includes a hydraulic unit having multiple actuators, a motor for driving the hydraulic unit, a first controller for controlling a first subset of the actuators of the hydraulic unit during mounting or dismounting of the accessory and a second controller for controlling a second subset of the actuators of the hydraulic unit during use of the accessory. The first controller is powered independently of the second controller and is operable to power the motor and control actuators from the first subset to mount or dismount the accessory from the vehicle without input from the second controller.
