Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gate devices in self-service financial apparatuses are vulnerable to illegal opening due to gaps between the gate and base plate, allowing criminals to manipulate the locking mechanism, compromising security.
Innovation Solution
A novel gate device employing a screw rod and sleeve mechanism driven by a single power motor, with a rack and gear system that locks the gate in both open and closed states, preventing manipulation by rigid sheets and ensuring high security and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swingable blocking member with gap is used to lock the gate, then the gate can be opened and closed, but criminals can insert rigid sheets through the gap to pull the locking mechanism
Solution Approach 1:
The patent replaces the traditional swingable blocking member mechanism with a sliding gate mechanism driven by a motor. The gate moves horizontally along guides rather than swinging, eliminating the gap that allowed rigid sheets to be inserted. The locking is achieved through the gate's position rather than a separate blocking member, making the system both more secure and easier to automate.
Solution Approach 2:
The gate system is divided into distinct functional components: the sliding gate body, the motor-driven transmission mechanism, the screw rod for positioning, and the sleeve component for locking. This segmentation allows each component to perform its specific function efficiently, with the screw rod providing precise positioning and the sleeve providing secure locking without requiring gaps.
2Reliability
If a complex locking mechanism with multiple components is used to prevent illegal opening, then security is improved, but the device complexity and occupation space increase
Solution Approach 1:
The patent combines multiple functions into integrated components. The sliding gate itself serves as both the barrier and the locking element when positioned correctly. The screw rod and sleeve work together as a unified positioning and locking system, eliminating the need for separate blocking members and reducing overall structural complexity while maintaining high security.
Solution Approach 2:
The gate structure performs multiple functions: it acts as a physical barrier, a movable component for opening/closing, and a locked position indicator. The screw rod serves both to position the gate and to engage with the sleeve for locking. This multi-functionality reduces the number of separate components needed, simplifying the overall device while enhancing security.
3Ease of operation
If a bi-directional motor with gear system is used to drive the gate, then precise control and locking in both states are achieved, but the device complexity increases
Solution Approach 1:
The patent uses a motor-driven system with a gear reduction mechanism and screw rod to replace complex multi-component locking mechanisms. The bi-directional motor provides precise control for both opening and closing operations, while the gear system and screw rod convert rotational motion into precise linear positioning, achieving accurate control with a relatively simple integrated mechanism.
