POS Cradle with Interchangeable Frames for Mobile Device Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compatibility of point of sale (POS) terminal devices with mobile computing devices of varying sizes and form factors is limited due to changes in device thickness, size, ports, and port locations, leading to compatibility issues between different models.
Innovation Solution
A POS terminal device with a cradle that uses interchangeable frames and a connector to securely hold and interface with mobile computing devices, reducing the need for additional connectors and enhancing compatibility across different models by providing power and data transfer while incorporating tamper detection circuitry for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed POS terminal device is used, then payment processing capability is maintained, but compatibility with various mobile computing devices of different sizes and form factors is limited
Solution Approach 1:
The POS terminal device is divided into a fixed housing and a removable cradle assembly. The cradle can be detached and replaced to accommodate different mobile computing device form factors, while the main housing containing payment processing components remains stationary. This segmentation allows compatibility with various devices without redesigning the entire system.
Solution Approach 2:
The cradle is designed with interchangeable frames that can accommodate different sizes and form factors of mobile computing devices. A single cradle mechanism can hold smartphones, tablets, or other mobile devices by swapping the appropriate frame, making the POS terminal universal across multiple device types while maintaining a fixed structure.
2Adaptability or versatility
If multiple connectors are used to interface with mobile computing devices, then compatibility is improved, but device complexity and interface requirements increase
Solution Approach 1:
Multiple connector functions are merged into a single integrated connector assembly within the cradle. This connector provides both data transfer and power delivery capabilities while maintaining a unified interface that works with different mobile computing devices. The consolidation reduces the number of separate connectors needed while preserving full functionality.
Solution Approach 2:
The integrated connector is designed to perform multiple functions simultaneously - data communication, power delivery, and device identification - through a single connection point. This universal connector works across different device types without requiring multiple specialized connections, simplifying the interface while maintaining compatibility.
3Reliability
If a fixed POS terminal is used, then transaction processing is reliable, but adaptability to different mobile computing device form factors is limited
Solution Approach 1:
The system is segmented into a reliable fixed housing that contains the payment processing logic and communication interfaces, and a flexible removable cradle that adapts to different device form factors. This separation ensures that transaction processing reliability is maintained in the fixed portion while form factor adaptability is achieved through the interchangeable cradle components.
Solution Approach 2:
The cradle incorporates adjustable and interchangeable components that can be dynamically configured to match different mobile computing device dimensions and connection requirements. The ability to swap frames and adjust positioning maintains reliable contact and connection while adapting to various device sizes and orientations.

AI summary
Point of sale (POS) systems and methods are described. A POS device includes a housing with a payment instrument reader. The payment instrument reader reads payment instrument information from a payment instrument in response to receipt of the payment instrument at a read area of the housing. The POS device includes a first fastening mechanism that secures the housing to a mount that is coupled to a surface of the environment. The POS device includes a cradle of the housing that receives a mobile computing device. The POS device includes a second fastening mechanism that secures the mobile computing device within the cradle. The POS device includes a connector coupled to the payment instrument reader and extending into the cradle. The connector is configured to couple to the mobile computing device in the cradle, to convey the payment instrument information from the payment instrument reader to the mobile computing device.
