Solution Overview

Problem

Developers face challenges in accessing the developer mode on third-party devices, as these devices often lack a developer switch, making them unusable for diagnostic purposes such as during the RMA process.

Innovation Solution

A developer switch is installed on all compatible devices, including third-party devices, and can be secured within or behind a Kensington security slot to prevent accidental activation, ensuring only authorized users can access the developer mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a developer switch is installed on all devices including third-party devices, then developers can access developer mode on any compatible device, but the device may be accessed by unauthorized users who can activate the switch to switch the OS to developer mode

Engineering Contradiction:
Improveaccess to developer modeVSAvoidsecurity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The developer switch is nested within the security slot mechanism, where the switch is positioned behind or within the slot that accepts a security lock. This allows the switch to be accessible only when the security slot is unlocked, providing both developer mode access and security control in a integrated structure

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The security slot acts as an intermediary mechanism between the unauthorized user and the developer switch. By requiring a security lock to be removed or deactivated before the switch can be accessed, the security slot mediates access control while preserving the switch's functionality for authorized users

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the developer switch is placed in a secure location within the device, then unauthorized users cannot access the switch, but the switch becomes difficult to access even for authorized users

Engineering Contradiction:
ImprovesecurityVSAvoidaccess to switch
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The developer switch is nested within the security slot mechanism, where the switch is positioned behind or within the slot that accepts a security lock. This allows the switch to be accessible only when the security slot is unlocked, providing both developer mode access and security control in a integrated structure

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The security lock mechanism is extracted as a separate removable component from the device body. By making the lock removable and independent, authorized users can easily remove it to access the developer switch, while the lock remains in place to prevent unauthorized access. This separates the security function from the switch access function

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A computing device comprising a security slot integral with an external surface of the computing device, wherein the security slot is configured to receive and mechanically cooperate with a blocking mechanism. In certain aspects, the computing device further comprises a switch mounted behind the security slot and integral to the computing device and configured to permit access to a developer mode when the switch is in a first position and to restrict access to the developer mode when the switch is in a second position.
