Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll-up strap systems in vehicles require complex and costly installations of electrical lines and electromechanical converters, increasing vehicle costs and safety concerns due to potential passenger operation of consoles.
Innovation Solution
A simplified, completely mechanical system using a central lever-operated central operating element with Bowden cables or rotary signal transmitters to control roll-up strap units, eliminating the need for wall or ceiling consoles and electromechanical converters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical lines and electromechanical converters are installed in the wall and ceiling to connect consoles to roll-up strap units, then the system can transmit control signals, but the installation becomes complex and costly
Solution Approach 1:
The patent replaces the electrical signal transmission system with a mechanical cable-driven system. Bowden cables connect the central operating element directly to the roll-up strap units, transmitting mechanical force instead of electrical signals. This eliminates the need for electromechanical converters and reduces installation complexity while maintaining reliable signal transmission through pure mechanical means.
Solution Approach 2:
The patent removes the electrical components (consoles, electric lines, electromechanical converters) from the system and extracts only the essential function of signal transmission. This is achieved by using mechanical cables that directly transmit the release signal from the central operating element to the roll-up strap units, simplifying the overall system architecture.
2Ease of operation
If multiple consoles are installed to simplify operation, then accessibility is improved, but the cost price and safety risks increase
Solution Approach 1:
The patent implements a single central operating element that controls all roll-up strap units in the vehicle. This universal control mechanism allows one operator to manage multiple straps simultaneously, eliminating the need for multiple separate consoles while reducing overall system complexity and cost.
Solution Approach 2:
The patent merges the control functions of multiple potential consoles into a single central operating element. This consolidation reduces the number of components, lowers installation costs, and minimizes safety risks associated with multiple access points that could be inadvertently operated by passengers.
3Ease of operation
If electromechanical converters are built into the central operating element and roll-up strap units, then electric signals can be converted to control movements, but the system becomes more complex and prone to malfunction
Solution Approach 1:
The patent eliminates electromechanical converters by replacing the electrical control system with a purely mechanical cable-driven system. The Bowden cables directly transmit mechanical force from the central operating element to the roll-up strap units, removing the need for any electromechanical conversion components and thereby reducing system complexity and potential failure points.

AI summary
There is disclosed a central mechanically operated and operating roll-up strap system comprising a central operating element and one or more roll-up strap units connected thereto. The system further comprises mechanical signal transmitters provided between the operating element and the roll-up strap units, the central operating element being provided with a locking mechanism and a lever connected to said unlocking mechanism and said signal transmitters, which lever supplies mechanical release signals to the roll-up strap units via the signal transmitters in one position, while said locking mechanism is arranged to maintain the release signals until locking signals are supplied to the roll-up strap units via the signal transmitters as a result of the locking mechanism being operated. The system is preferably integrated in the floor of a vehicle.
