Remote Cable Unlocking Mechanism for Vehicle Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for locking and unlocking openings in vehicles or trailers require manual movement to multiple control means, which is inconvenient and inefficient, especially when security measures involve multiple locking systems.
Innovation Solution
A device with a prestressed locking mechanism, a control means with a housing and cable, and a guide means allowing the control to be operated remotely along a predefined trajectory, enabling the locking means to be unlocked from a variety of positions, including a steering wheel design for ergonomic operation and adaptable to user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate control means are used for security, then security is improved, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines multiple separate control means into a single integrated control handle that can simultaneously operate multiple locking mechanisms. The control handle is designed with multiple actuating elements that can engage different locks in sequence or simultaneously, allowing the user to unlock multiple security systems with one unified action rather than moving between separate controls.
Solution Approach 2:
The single control handle is designed to perform multiple functions by incorporating different actuating mechanisms that can engage various locking systems. This universal control device can handle different types of locks (latches, hooks, bolts) through a unified interface, making the control system adaptable to multiple security requirements while maintaining ease of operation.
2Reliability
If control means are located in immediate vicinity of closure device, then control reliability is improved, but operational efficiency deteriorates due to repeated movement
Solution Approach 1:
The patent merges multiple control functions into a single control handle that remains stationary or is positioned optimally for user access. Instead of requiring the user to move between multiple control points located near different closure devices, the unified control handle consolidates all control functions in one location, improving operational efficiency while maintaining control reliability through proper mechanical linkage to all locking mechanisms.
3Ease of operation
If a single control means operates multiple locks simultaneously, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control handle is segmented into multiple independent actuating elements or sections, each responsible for engaging a specific locking mechanism. This segmentation allows the complex function of operating multiple locks to be broken down into simpler, modular components within the single control device, making the internal mechanism more manageable and easier to maintain while preserving ease of operation.
Solution Approach 2:
The control handle incorporates dynamic elements such as spring-loaded actuators, cam mechanisms, or linkage systems that automatically sequence the engagement of multiple locks. These dynamic components simplify the control architecture by using mechanical intelligence to manage the complexity of coordinating multiple locking mechanisms, reducing the need for complex electronic control systems while maintaining ease of operation.

AI summary
This opening release device comprises: a locking means (110), a cable (120), a control means (130), and a guide means. The cable is fixed at two points, and at least one of these points is fixed to the locking means. The control means is slidably mounted on the guide means along a first path between point A and point B. The control means has a housing through which the cable passes, said housing being slidably mounted along a second path between a rest position and an actuated position, said rest position keeping the cable substantially under tension, and said actuated position being capable of exerting a pull on the cable causing the locking means to move from the closed position to the open position, independently of the location of said control means between A and B.
