Truck Cap Door Latch Control for Handle-Free Remote 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 locking/latching structures.
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 manual operation in case of electronic failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mechanical actuation is used to open the truck bed cover door, then the door can be opened with simple mechanical structures, but the operation convenience is poor and design possibilities are limited
Solution Approach 1:
The patent replaces the manual mechanical actuation system with an automated motor-driven latch release assembly. The motor actuator automatically moves the latch arm to release the latch bar, eliminating the need for manual handle operation and mechanical key systems, thereby improving ease of operation while managing complexity through electronic control
Solution Approach 2:
The latch release assembly is designed to automatically release the door latch through motor actuation triggered by electronic signals from keypads, phone apps, or wireless devices. The system serves itself by automatically performing the latching and unlatching functions without requiring manual intervention, enhancing operational convenience
2Extent of automation
If motor actuated latch release assembly is used, then automatic door operation is achieved, but the device complexity increases
Solution Approach 1:
The controller is designed to accept multiple types of input signals from different sources including keypads, phone apps, and wireless devices. This multi-functional capability allows a single control system to handle various authentication methods and trigger the motor actuator, achieving high automation while managing complexity through a unified control architecture
Solution Approach 2:
The patent introduces a controller as an intermediary between the input devices (keypads, phone apps, wireless devices) and the motor actuator. This intermediary component coordinates the automated door release process by receiving electronic signals and activating the motor, thereby achieving automatic operation while organizing system complexity through a centralized control mechanism
3Reliability
If mechanical override assembly is included for manual operation, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent incorporates a mechanical override assembly as a backup system that can manually release the latch bar in case of electronic system failure. This beforehand cushioning approach ensures that the door can still be opened even when the automated motor actuated system is non-functional, thereby improving reliability while adding a controlled level of mechanical complexity
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
Provides convenient automatic door operation without the need for manual handles or latching structures, enhancing user experience and design flexibility while maintaining a hardware-free appearance.
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.
