One-Time Programming Undo for Storage Configuration Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of computing device manufacturing is increased by the need to stock and manage different storage devices with various personality configurations, which can lead to issues such as storage devices being locked into specific configurations and unable to be reused if orders are cancelled.
Innovation Solution
A system that includes a one-time programming subsystem to configure components with specific personality configurations and a one-time programming undo subsystem to authenticate and execute instructions that allow modification of these configurations, thereby enabling the reversal of one-time programming operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage devices are programmed with one-time programming to lock into specific personality configurations, then compliance with jurisdictional requirements is ensured, but the storage devices become unusable for other configurations if orders are cancelled
Solution Approach 1:
The patent introduces a dynamic unlock mechanism that transitions the storage device from a locked state (ensuring compliance) to an unlocked state (enabling flexibility). The one-time programming operation sets an initial locked state, but the undo operation can dynamically change this state, allowing the same device to serve different jurisdictions and configurations.
Solution Approach 2:
The patent changes the state parameter of the storage device from locked to unlocked by introducing an undo operation. This parameter change allows the storage device to transition between different operational states, enabling it to be used in different jurisdictions and configurations without physical replacement.
2Productivity
If multiple types of storage devices with different personality configurations are stocked to meet various jurisdictional requirements, then customer order fulfillment is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent makes a single storage device type universal by enabling it to perform multiple functions through configuration changes. Instead of maintaining separate inventories for different jurisdictions, the same storage device can be programmed with different personality configurations and unlocked for use in different regions, eliminating the need for multiple device types.
Solution Approach 2:
The patent uses parameter changes to transform a single storage device into a multi-functional component. By changing the personality configuration parameter through programming operations, the same physical device can satisfy different jurisdictional requirements, reducing inventory diversity and manufacturing complexity.
3Reliability
If storage devices are locked into specific configurations to prevent unauthorized modifications, then security is improved, but the ability to restock and reconfigure cancelled orders is lost
Solution Approach 1:
The patent introduces a dynamic state change mechanism that allows the storage device to transition from a secure locked state to an unlocked restocking state. The one-time programming operation provides initial security, while the undo operation enables controlled unlocking for restocking, balancing security with manufacturing flexibility.
Solution Approach 2:
The patent introduces an intermediary undo operation that mediates between the locked state (providing security) and the unlocked state (enabling restocking). This intermediary mechanism allows authorized transitions between states without compromising either security or restocking capability, acting as a bridge between the two opposing requirements.

AI summary
A secure one-time programming undo system includes a component and a component configuration system. A one-time programming subsystem in the component configuration system provides the component with personality configuration information that configures the component to perform component operations, and performs a one-time programming operation that configures a component engine in the component to deny modification requests to modify the personality configuration information. A one-time programming undo subsystem in the component configuration system performs a one-time programming undo authentication operation, and transmits a one-time programming undo instruction that is associated with the one-time programming undo authentication operation to the component, with the one-time programming undo authentication operation configured to authenticate the one-time programming undo instruction to the component such that the component executes the one-time programming undo instruction that reconfigures the component engine in the component to allow modification requests to modify the personality configuration information.
