Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple peripheral devices are turned on concurrently to connect to the information handling system, then the pairing process becomes more complex and collisions occur, but if a sequential pairing process is used, then the pairing time increases and productivity decreases

Engineering Contradiction:

Improvepairing success rateVSAvoidpairing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a gateway peripheral device as an intermediary that coordinates the pairing process between multiple peripheral devices and the information handling system. The gateway device receives pairing requests, manages the pairing sequence, and relays authentication information, thereby reducing collisions and simplifying the overall pairing complexity while maintaining high pairing success rates.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If alphanumeric codes are required for pairing authentication, then security is improved, but headless devices without input capabilities cannot be paired

Engineering Contradiction:

Improvepairing securityVSAvoiddevice compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a self-service pairing mechanism where the gateway peripheral device automatically generates and transmits authentication codes to both the information handling system and subordinate peripheral devices. This eliminates the need for manual alphanumeric code input on headless devices while maintaining security through automated cryptographic authentication.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The gateway device acts as a mediator that handles the authentication code generation and distribution. It receives the alphanumeric code from the information handling system and automatically forwards the appropriate authentication credentials to subordinate peripheral devices, enabling headless devices to pair securely without input capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If a gateway peripheral device coordinates the pairing of multiple devices, then pairing collisions are minimized, but the device complexity increases

Engineering Contradiction:

Solution Approach 1:

The gateway peripheral device leverages existing multi-functional capabilities already present in modern peripheral devices (such as Bluetooth Low Energy stack, cryptographic processing, and wireless communication) to perform coordination functions. This approach minimizes the need for additional specialized hardware or software, thereby reducing the actual complexity increase while maintaining high pairing efficiency.

Inventive Principle:

Solution Approach 1:

The system implements automated authentication where the gateway device and information handling system handle code generation and verification without requiring user interaction. The gateway device automatically inputs codes on behalf of headless peripheral devices, and the system performs cryptographic verification, maintaining security while eliminating manual input requirements for improved ease of operation.

AI summary

A peripheral device operatively couplable to an information handling system includes a microcontroller, a storage device, a wireless radio, and a power management unit (PMU) to provide power to the hardware microcontroller, storage device, and wireless radio. The hardware microcontroller executes computer-readable program code of a wireless pairing anti-collision module to determine that a group ID pairing beacon from one of a plurality of competing pairing peripheral devices is not being broadcasted. When no group ID pairing beacon is detected, the hardware microcontroller initiates a pairing process with the information handling system and generates a passcode list for pairing via a hash loop algorithm. The hardware microcontroller transmits to each competing pairing peripheral device an indication that the peripheral device is operating as a gateway peripheral device that controls the timing of the pairing of each of the plurality of competing pairing peripheral devices to the information handling system.
