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
Engineering 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
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
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
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
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
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
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
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
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
