Solution Overview

Problem

Existing transaction card reading systems with protective shutters are complex to manufacture, assemble, and prone to breakdowns, while also being bulky and expensive, due to the integration of numerous elements such as springs, sensors, and motors.

Innovation Solution

A transaction card reading system with a protective flap that uses an elastically deformable portion on a single-piece support element, allowing the flap to move between open and closed positions without external springs, and is formed from a metallic blade and plate, simplifying production and assembly, and incorporating lifting pads for standard card detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protective flap with external springs and mechanical return mechanisms is integrated into the card reader, then the insertion slot is protected from unauthorized access, but the device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveprotection of insertion slotVSAvoidcomplexity of protective flap mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the return spring mechanism from the protective flap assembly and relocates it to the card reader housing. This separation allows the protective flap to be a simple, springless component that pivots on a single axis, while the housing contains the return spring that automatically resets the flap to its closed position. This extraction resolves the contradiction by eliminating complex integrated mechanisms while maintaining protective functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The protective flap mechanism is segmented into distinct functional components: the protective flap itself (a simple pivoting barrier), the pivot axis (providing rotational movement), and the return spring (providing automatic resetting). This segmentation allows each component to be simple and independent, reducing overall device complexity while maintaining the reliability of the protective function.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple external components (springs, sensors, motors) are integrated into the protective flap mechanism, then the protective function is enhanced, but the ease of manufacture and assembly deteriorates

Engineering Contradiction:
Improveprotective functionVSAvoidease of assembly
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The return spring is extracted from the protective flap assembly and mounted in the housing, transforming a complex integrated mechanism into simple, separable components. This allows the protective flap to be manufactured and assembled independently as a simple pivoting element, while the spring mechanism is separately installed in the housing, significantly improving ease of manufacture and assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The protective flap mechanism is designed to be self-actuating through the return spring, which automatically resets the flap to its closed position without requiring external power sources, sensors, or motors. This self-service mechanism eliminates complex electronic and mechanical subsystems, improving both manufacturability and reliability while maintaining the protective function.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If automated sensors and motorized opening mechanisms are added to the protective flap, then the ease of operation is improved, but the device complexity and cost increase

Engineering Contradiction:
Improveautomatic opening of protective flapVSAvoidcomplexity of automated mechanisms
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The protective flap is designed to open automatically when a card is inserted, using the card itself as the actuating force. The card's insertion movement directly pivots the protective flap open, eliminating the need for sensors or motors. This self-service approach improves ease of operation while maintaining mechanical simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The protective flap is pre-positioned to be automatically displaced by card insertion, creating a preliminary action that opens the flap before the card needs to access the reader interior. This preliminary anti-action (pre-positioning the flap to be moved by card insertion) simplifies operation without requiring automated control systems.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

The invention relates to a payment card reading system comprising: a payment card reader (1) comprising a slot (11) for inserting a payment card; and a protective flap (2) that is movable between two positions: a closed position, in which the flap shuts said insertion slot, and an open position, in which the flap is disposed at least partially away from said insertion slot. The protective flap (2) comprises a shutting element (22) mounted securely on a one-piece support element (21), said shutting element (22) being shaped and dimensioned to shut said insertion slot (11) in said closed position, said one-piece support element (21) comprising at least one elastically deformable portion (211) so as to allow the passage from the closed position to the open position and vice versa.
