Solution Overview

Problem

Electronic devices face challenges in normal operation of moving housing components due to temperature changes and foreign substance introduction, which affect the mechanical structures and hinder the normal sliding of housings accommodating electronic components.

Innovation Solution

The electronic device employs a method involving a driving unit, sensors, and a processor to control the movement of a second housing within a first housing, adjusting driving frequencies based on temperature and position to minimize the impact of temperature changes and foreign substances, ensuring normal sliding functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a driving unit with driving motor is used to move the housing accommodating electronic components, then the housing can be moved between accommodated and protruded positions, but temperature changes and foreign substance introduction cause mechanical structure characteristics to change, preventing normal operation

Engineering Contradiction:
Improvehousing movement operationVSAvoidoperation reliability under temperature change
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by detecting the temperature of the driving motor before driving the housing, and in advance clearing any foreign substances from the sliding path. This preventive approach ensures the housing can move normally even when temperature changes or foreign substances are present, resolving the reliability issue without affecting the ease of operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms by using temperature sensors to monitor the driving motor temperature and position sensors to detect housing position. Based on this feedback, the control unit adjusts driving parameters or triggers clearing operations, ensuring reliable operation under varying temperature conditions while maintaining ease of use

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the driving unit drives the housing to protrude or accommodate, then the electronic component function can be executed or stopped, but foreign substances may be introduced to the mechanical structure, hindering normal sliding

Engineering Contradiction:
Improveelectronic component function adaptabilityVSAvoidforeign substance introduction
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the taking out principle by extracting the foreign substance clearing function as a separate preliminary operation before the main housing movement. The control unit detects foreign substances and triggers a clearing mechanism to remove them from the sliding path, preventing interference with housing movement while maintaining the adaptability of electronic component functions

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary clearing of foreign substances from the mechanical structure before driving the housing to move. This preventive action ensures that foreign substances do not interfere with the sliding operation, allowing the electronic component functions to be executed or stopped reliably without contamination issues

Inventive Principle:
Principle #10Preliminary action

3Temperature

If temperature changes occur in the electronic device, then the characteristics of mechanical structures including the driving unit change, but this prevents the housing from moving normally

Engineering Contradiction:
Improvetemperature variation toleranceVSAvoidhousing sliding functionality
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent applies preliminary action by detecting the temperature of the driving motor before initiating housing movement. Based on the detected temperature, the control unit adjusts driving parameters or performs preliminary clearing operations to compensate for temperature-induced characteristic changes in the mechanical structure, ensuring normal housing sliding functionality across different temperature conditions

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes driving parameters based on detected temperature conditions. The control unit adjusts motor driving current, speed, or torque parameters according to the temperature of the driving motor, compensating for temperature-induced changes in mechanical structure characteristics and maintaining ease of housing operation across varying temperatures

Inventive Principle:
Principle #35Parameter changes
