Universal POS Housing with Interchangeable Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing POS systems require multiple specific housings for different peripheral devices, leading to high production costs and significant effort when changing devices, as each housing must be replaced along with the peripheral device.
Innovation Solution
A device with an adapter and interchangeable covers allows for easy attachment of various peripheral devices to a cash register screen using a single housing type, reducing manufacturing costs and enabling operators to swap devices without requiring service personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a peripheral-specific housing is used for each peripheral device, then the peripheral device can be securely attached to the screen, but the production volume of housings is small leading to high manufacturing costs
Solution Approach 1:
The patent implements a universal housing design that can accommodate multiple different peripheral devices through interchangeable adapters. Each adapter is specifically designed for a particular peripheral device type, while the housing itself remains standardized. This allows the same housing to securely attach various peripherals (barcode scanners, cash drawers, receipt printers, etc.) without requiring multiple housing types, thereby increasing production volume and reducing manufacturing costs while maintaining secure attachment for each device type.
Solution Approach 2:
The attachment system is segmented into three distinct components: the universal housing, the peripheral-specific adapter, and the mounting mechanism. This segmentation allows the housing to be produced in large quantities as a standardized component, while adapters can be produced in smaller volumes for specific device types. The modular structure enables the housing to maintain secure attachment capabilities for different peripherals without requiring custom housing designs for each device.
2Reliability
If a peripheral-specific housing is used for each peripheral device, then the device can be properly enclosed and protected, but the housing must be replaced when the peripheral device is changed, creating significant additional work
Solution Approach 1:
The universal housing serves multiple functions: it provides protection and enclosure for different peripheral devices, serves as a standardized mounting interface, and accommodates various adapters. When a peripheral device needs to be changed, only the adapter and peripheral device are replaced while the housing remains in place, significantly reducing the time and effort required for device changes compared to replacing the entire housing assembly.
Solution Approach 2:
The system is designed to be dynamically adaptable through the interchangeable adapter mechanism. The adapter can be quickly detached and replaced to accommodate different peripheral devices, while the housing provides stable, permanent mounting. This dynamic adaptation capability allows operators to change peripheral devices without the time-consuming process of replacing the entire housing structure.
3Adaptability or versatility
If multiple housing types are produced for different peripheral devices, then each device can be optimally designed, but the variety of housing types increases production complexity
Solution Approach 1:
The universal housing design provides a standardized platform that can accommodate multiple peripheral device types through interchangeable adapters. This single housing design replaces the need for multiple specialized housing types, reducing production complexity while maintaining compatibility with various peripheral devices. The housing includes standardized mounting interfaces and attachment mechanisms that work with different adapters.
Solution Approach 2:
The adapter serves as an intermediary component between the universal housing and the peripheral device. Each adapter is specifically designed to interface with a particular peripheral device type while connecting to the standardized housing mounting interface. This intermediary approach allows the housing to maintain a simple, standardized design while still providing optimal attachment and compatibility for diverse peripheral devices through the adapter layer.

AI summary
The device (10) has a housing part (14) comprising two recesses (22, 24) and a fastening element for securing peripheral device-specific covers for partial and/or complete closing of one of the recesses via a releasable and restorable connection. A peripheral device is fastened on the cover. The housing part is designed such that all peripheral specific covers for partial and/or the complete closing of the recess are fixable. The cover is fed into the housing part via the other recess of the housing part. An independent claim is also included for a point of sale system.
