Truck Cap Door Latch Control With Motorized Low-Voltage Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck bed covers require manual mechanical actuation to open, which can be inconvenient and limits design possibilities due to the need for latching and locking mechanisms.
Innovation Solution
A low voltage system controller with a motor actuated latch release assembly that allows the truck bed cap door to be automatically unlatched via electronic signals from devices like keypads, phone apps, or wireless devices, and includes a mechanical override for reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mechanical actuation is used to open the truck bed cap door, then the system structure is simple, but the ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical actuation with an automated motorized latch release system. A motor actuator automatically releases the latch bar from the latch arm, eliminating the need for manual manipulation of mechanical components. This substitution of manual mechanical operation with automated motorized operation directly improves ease of operation while accepting increased device complexity.
2Ease of operation
If motor actuated latch release assembly is used, then the ease of operation improves, but the device complexity worsens
Solution Approach 1:
The patent extracts the complex motorized latch release mechanism as a separate, self-contained assembly. The motor actuator, latch arm, and latch bar are integrated into a modular unit that can be independently controlled by the low voltage system controller. This extraction allows the complexity to be contained in a specific subsystem while maintaining overall system manageability and improving ease of operation through automated control.
3Extent of automation
If automatic door release system is implemented, then the extent of automation improves, but the device complexity worsens
Solution Approach 1:
The low voltage system controller serves multiple functions: it controls the motor actuated latch release assembly, monitors system status, and interfaces with various input devices (keypads, phone apps, wireless devices). By consolidating these control functions into a single multi-functional controller, the patent achieves high extent of automation while managing device complexity through functional integration rather than proliferation of separate components.
4Reliability
If mechanical override assembly is included, then the reliability improves, but the device complexity worsens
Solution Approach 1:
The patent incorporates a mechanical override assembly as a pre-prepared backup system. The override mechanism, including the rotating member and cable system, is installed in advance to provide a manual release capability if the motorized system fails. This beforehand preparation ensures reliability by having a fallback option ready, while the override mechanism is designed as a separate, simple mechanical system that adds minimal complexity to the overall automated system.
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
Enables convenient automatic opening of the truck bed cap door without the need for manual latching mechanisms, enhancing user experience and design flexibility while maintaining reliability through a low voltage electrical system.
Implementation Method 1
The latch release assembly includes a motor actuator... A signal from the controller activates the motor which moves the clip
Data Source
AI summary
A truck cap assembly that selectively covers a truck bed of a truck is provided. The truck cap assembly may include a cap that sets on opposing side walls of the truck; a cap door located on the cap; a latch bar located on the cap; a controller located on the cap door; and a latch release assembly which includes an actuator and a latch arm. The controller is in electrical communication with an actuator that is coupled to a latch arm. A signal from the controller activates the actuator to move the latch arm. The latch arm is releasable from the latch bar to release the cap door.
