Cargo Vehicle Door Winch Closure Against Lock Tampering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles designed for transporting valuable objects face challenges in preventing unauthorized access due to the limited tamper resistance of their locking systems, which can be easily compromised by ill-intentioned individuals.
Innovation Solution
Incorporation of a winch system with a hook, cable, and motor inside the vehicle body, secured to the doors via attaching means, allowing remote control operation to keep the doors closed and prevent unauthorized access, even if the locking control means deteriorate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking means are used to secure doors, then door closure is achieved, but tamper resistance is limited
Solution Approach 1:
The patent applies the dynamics principle by replacing static locking means with a dynamic winch system that can actively adjust and maintain door closure force. The winch mechanism can dynamically respond to tampering attempts by maintaining continuous tension on the cable, making the door closure system adaptive rather than fixed, thereby improving resistance to tampering while ensuring reliable door closure.
Solution Approach 2:
The patent implements preliminary action by pre-tensioning the cable through the winch system before any tampering occurs. The winch is configured to maintain constant tension on the cable connected to the door, so that when tampering attempts are made, the door is already under secure tension from the pre-applied force, rather than relying solely on passive locking mechanisms that react only when engaged.
2Reliability
If locking means are used to secure doors, then access prohibition is achieved, but control means are vulnerable to tampering
Solution Approach 1:
The patent applies mechanics substitution by replacing the traditional mechanical locking control system with a winch-based mechanical advantage system. Instead of relying on vulnerable lock and key control means, the invention uses a cable-and-drum winch mechanism where the door is secured through cable tension rather than mechanical interlocking, thereby improving access control reliability while reducing vulnerability to conventional tampering methods.
Solution Approach 2:
The control system transitions from static locking control to dynamic winch control. The winch can be remotely operated to adjust cable tension and maintain door closure actively, providing a more reliable access control mechanism that is less susceptible to tampering compared to traditional locking controls.
3Object-affected harmful factors
If a winch system is added to improve security, then tamper resistance is enhanced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the winch system to serve multiple functions: it acts as both a door closing mechanism and a security anti-tampering device. The same winch assembly that closes the door also provides continuous tension to prevent tampering, eliminating the need for separate locking and security systems, thereby enhancing tamper resistance while minimizing the increase in overall system complexity.
Solution Approach 2:
The invention merges the door closing function and the security function into a single integrated winch system. The cable connected to the door serves dual purposes: it enables door closure and simultaneously provides tamper resistance through continuous tension, combining what would traditionally require separate systems into one unified mechanism.

AI summary
The vehicle for transporting objects includes a body which is intended to contain these objects, and the body comprises at least one opening and at least one door. Each door closes such an opening, and which, depending on the circumstances, prohibits or permits entry inside the body. The vehicle also includes a winch which is located inside the body and includes a hook, a cable having a free end that is provided with this hook, a drum for winding the cable, and a motor for driving this drum. The vehicle also includes a securing device for fixedly securing the winch to the body, at least one attaching device which the at least one door includes, while the hook of the winch engages directly or indirectly with the at least one attaching device, and remote controller for the motor of the winch.
