Solution Overview
Problem
During the assembly of portable electronic devices, there is a risk of damage due to excessive electrical current passing through the power module when it is not the last component assembled, and hot swapping expansion devices often experience electrical conduction errors from misconnections, necessitating a solution to ensure the power source conduction path is complete only after structural connections are finished.
Innovation Solution
An electronic device with circuit protection and an assembling method that uses a control unit and circuit protection unit to manage the electrical connection between modules, where the assembling unit is the last component assembled, ensuring the power source is isolated until the assembly is complete, and a trigger signal is used to enable electrical connections only after the assembly is finalized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the power module is installed early in the assembly process, then the assembly can proceed efficiently, but excessive electrical current may pass through causing damage to electronic components
Solution Approach 1:
The patent applies preliminary action by installing the power module early in the assembly process but keeping it in a non-conducting state through a disconnected circuit path. The power module is physically positioned and connected to other components before final assembly, but electrical conduction is prevented until the assembling unit is fully installed, thus preparing the system in advance while maintaining safety.
Solution Approach 2:
The patent uses an intermediary mechanism (the circuit protection unit and control unit) that mediates between the power module and the rest of the electronic components. This intermediary controls the electrical connection state, allowing the power module to be present and connected structurally while blocking excessive current until the assembly is complete, thus resolving the contradiction between early installation and component protection.
2Ease of operation
If electrical connection terminals are connected during hot swapping expansion, then the device becomes functional, but misconnections may cause electrical conduction errors
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring the circuit protection unit to prevent incorrect electrical connections before they can cause damage. The control unit monitors the assembly state and actively blocks electrical conduction until proper structural connections are confirmed, thus counteracting potential misconnection errors before they affect device functionality.
Solution Approach 2:
The patent implements feedback through the control unit that continuously monitors whether the assembling unit is properly installed and structurally connected. Only when the feedback confirms correct structural assembly does the control unit enable electrical conduction, thus ensuring electrical connection accuracy while maintaining ease of operation through hot swapping capability.
3Ease of operation
If the power source conduction path is activated early, then the device can be tested and operated, but structural components may be damaged by excessive current
Solution Approach 1:
The circuit protection unit serves as an intermediary between the power source and structural components. It allows the power source to be activated for testing purposes while blocking harmful electrical current from reaching structural components that are not yet fully assembled, thus enabling device testability without causing electrical damage.
Solution Approach 2:
The patent applies local quality by creating different electrical states in different parts of the system. The circuit protection unit enables selective electrical conduction - allowing power to reach certain components for testing while blocking current to other structural components that are not yet ready, thus enabling localized testing without widespread electrical damage risk.
