Solution Overview

Problem

Desktop and notebook computers face inefficiencies in heat dissipation, which affects their operation performance, and existing solutions do not effectively prevent movable parts from getting blocked or clamped, potentially causing damage or injury.

Innovation Solution

A computer host design incorporating a movable portion, an actuator module, a detection module, and a processing module that allows the movable portion to open or close to form airflow channels for improved heat dissipation, while detecting output variations to prevent blocking or clamping through reverse actuation signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the movable portion is opened to form an airflow channel, then the heat dissipation efficiency is improved, but the risk of blocking or clamping increases

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoidblocking or clamping risk

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The detection module continuously monitors the output value of the actuator module during movable portion operation. When a blockage or clamping is detected through output value changes, the system provides feedback to the processing module, which then sends a reverse actuation signal to the actuator module to reverse the movable portion's movement, preventing damage while maintaining heat dissipation functionality

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by detecting potential blockages or clamping conditions before they cause damage. The detection module identifies abnormal output values that indicate impending blockage, and the processing module sends reverse actuation signals to prevent the blockage or clamping from occurring in the first place

Inventive Principle:

Principle #9Preliminary anti-action

2Ease of operation

If the actuator module output value is increased to overcome blocking, then the movable portion can be opened, but the risk of clamping or damage increases

Engineering Contradiction:

Improvemovable portion operationVSAvoidclamping or damage risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The detection module monitors the actuator module's output value in real-time. When the output value changes indicate blocking or clamping, the system provides feedback to reverse the actuation, preventing further increase in output that could cause damage while maintaining operational capability

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system converts the harmful effect of blockage or clamping into a beneficial protective action. The detection module identifies the blockage condition, and instead of forcing higher output that could cause damage, the system reverses the actuation to safely resolve the blockage, turning a potentially harmful situation into a safe operational state

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A computer host with a housing includes a movable portion, an actuator module, a detection module and a process module. The movable portion constitutes a first portion of the housing. The actuator module actuates the movable portion to execute an operation. The detection module detects an output value of the actuator module, and outputs a detection signal when the output value is varied. The processing module sends a reverse actuation signal to the actuator module according to the detection signal so that the actuator module reversely actuates the movable portion.
