Coin Machine Protector with Articulated Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection systems for coin-operated machines are complex, costly, and difficult to manufacture and install, often requiring large spaces and not effectively addressing vulnerabilities in the front piece or printed screen, which are increasingly targeted by thieves.
Innovation Solution
A protection system comprising a metal frame with a polycarbonate panel, mounted directly on the machine's front piece, using articulated or pinned arms for secure attachment, allowing easy installation and access without removing the protection, reinforced with additional arms for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective cabinets with moving bodies and shutters are used, then protection effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The protective cabinet is divided into a fixed body and a movable body that can be independently positioned. The movable body includes a shutter that can be raised or lowered, allowing the protection system to be segmented into functional zones that can be activated or deactivated independently, simplifying the overall structure while maintaining effectiveness.
Solution Approach 2:
The protective cabinet incorporates a movable body with a shutter that can dynamically change position between raised (protective) and lowered (accessible) states. This dynamic element allows the system to adapt between protection and access modes without requiring complex locking mechanisms throughout the entire structure.
2Reliability
If protective cabinets with guide rails and folded doors are used, then protection effectiveness is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The protection system is segmented into a fixed cabinet body and a separate movable protective element. This segmentation allows each component to be manufactured independently using simpler processes, reducing overall manufacturing complexity and cost while maintaining the protective function.
Solution Approach 2:
The movable protective element is extracted as a separate component from the fixed cabinet body. This extraction allows the protective function to be achieved through a simpler, more cost-effective design that doesn't require the entire cabinet structure to be complex, focusing the complexity only where necessary for protection.
3Reliability
If traditional protective cabinets requiring full removal for access are used, then protection effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The access system is segmented into a main cabinet body and a removable drawer component. The drawer can be independently removed to access the coin box, allowing maintenance personnel to access internal components without removing the entire protective cabinet, thus maintaining protection effectiveness while improving operational convenience.
Solution Approach 2:
The drawer component is designed to be dynamically removable and reattachable, providing flexible access to the coin box and internal components. This dynamic access mechanism allows the system to transition between protected and accessible states selectively, improving ease of operation without compromising overall protection.

AI summary
Protection system for coin-operated machines which comprises a protector made of a combination of metal and polycarbonate, for arrangement directly on the panel of the machine, provided with upper arms fixed to the side of the machine, either in an articulated manner or by means of a pin, and provided with other lower arms fixed to the side of the machine, both upper and lower arms embracing and fixed to the sides of the machine, which may be additionally provided with an additional arm (8) for reinforced fastening, which may be articulated or unfolding. The described system achieves a protection system that easy to manufacture, easy to install, simple to handle and which offers good protection.
