Interface Adapter for CRUM Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machines designed to communicate with older customer replaceable unit monitors (CRUMs) having different interface formats require costly hardware replacements to accommodate newer, less expensive CRUM technology, which is not compatible with their mechanical, electrical, and data interface formats.
Innovation Solution
An adapter is installed in the machine to enable data communication between the machine and a CRUM with a different interface format, allowing for the use of newer CRUMs without replacing the machine's hardware by converting between the interface formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a machine is designed to communicate with older CRUMs having a specific interface format, then the machine can work with compatible modules, but it cannot communicate with newer CRUMs having different interface formats without costly hardware replacement
Solution Approach 1:
The patent introduces an adapter as an intermediary device that bridges the gap between the machine's original interface format and the newer CRUM's different interface format. The adapter converts signals and data between the two incompatible formats, enabling communication without requiring hardware replacement in the machine itself.
Solution Approach 2:
The solution segments the interface compatibility problem into separate components: the machine maintains its original interface, the adapter provides format conversion, and the newer CRUM uses its own interface format. This segmentation allows each component to remain optimized for its specific format while achieving overall compatibility.
2Reliability
If newer CRUM technology is incorporated into machines designed for older CRUMs, then CRUM capabilities are improved, but manufacturing cost and installation complexity increase due to hardware replacement requirements
Solution Approach 1:
The adapter serves as a mediator that allows newer CRUM technology to be introduced without modifying the machine's original hardware. The adapter handles the interface translation, enabling the machine to work with enhanced CRUM capabilities while avoiding costly hardware replacement and simplifying installation.
3Adaptability or versatility
If the machine hardware is replaced to accommodate newer CRUM interface formats, then compatibility is achieved, but the machine's life cycle is shortened and costs increase
Solution Approach 1:
The adapter acts as a bridge that enables the machine to continue operating with newer CRUMs without hardware replacement. This extends the machine's life cycle by allowing it to adapt to new technologies through the intermediary adapter rather than requiring its own hardware replacement.
Solution Approach 2:
The adapter provides universal interface compatibility, allowing the machine to work with both older and newer CRUM formats through a single adapter device. This multi-functionality eliminates the need for hardware replacement and extends the machine's operational life.

AI summary
An adapter suitable for installation in a machine in place of a customer replaceable unit monitor having a first interface format is described herein. Upon installation of the adapter in the machine, the adapter enables data communication between the machine and a customer replaceable unit monitor having a second interface format that is different than the first interface format. The first and second interface formats may include one or more of: configuration of an electrical interface of the customer replaceable unit monitor, configuration of a mechanical interface of the customer replaceable unit monitor, and configuration of data input to and output from the customer replaceable unit monitor. The adapter may be attached to a module before the module is installed in the machine to simplify installation of the adapter. The adapter may remain attached to the machine when the module is removed from the machine to allow the machine to communicate with other customer replaceable unit monitors having the second interface format. The second customer replaceable unit monitor may include a microprocessor and non-volatile memory disposed in a common package.
