Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching power supply solutions fail to meet power control and over-temperature protection requirements across various installation directions, particularly under natural heat dissipation conditions, as they are designed for fixed installations and cannot adapt to changing orientations.
Innovation Solution
A switching power supply system that includes a direction detection module to obtain installation direction information, a sampling module to monitor temperature, and a process module to perform preset operations based on this information, using a mapping relationship between installation directions and temperature threshold values to ensure effective over-temperature protection and power control in all installation directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If external forced cooling measures are used, then temperature control is improved, but system reliability and service life are reduced
Solution Approach 1:
The patent implements dynamic temperature threshold adjustment based on installation direction detection. The system uses a direction detection module to identify the installation orientation and dynamically selects appropriate temperature thresholds from a mapping relationship, enabling adaptive temperature management without forced cooling measures.
Solution Approach 2:
The system changes the temperature parameter dynamically according to installation direction. Different temperature thresholds are set for different installation directions (e.g., upward, downward, horizontal), allowing the power supply to operate safely under natural heat dissipation conditions specific to each orientation.
2Ease of manufacture
If fixed installation design is used, then manufacturing simplicity is improved, but adaptability to different installation directions is reduced
Solution Approach 1:
The patent makes the power supply universally applicable to all installation directions by incorporating a direction detection module that automatically identifies the installation orientation. The system can be installed in any direction (upward, downward, horizontal, etc.) and will automatically adjust its operation accordingly, eliminating the need for direction-specific design variants.
Solution Approach 2:
The system performs self-adjustment based on its own detected installation direction. The direction detection module automatically determines the installation orientation and triggers the appropriate temperature threshold configuration without requiring external intervention or manual setup, enabling the system to serve itself across different installation scenarios.
3Reliability
If natural heat dissipation is used, then system reliability is improved, but heat dissipation capability requirements are increased
Solution Approach 1:
The patent applies different temperature thresholds for different installation directions based on local heat dissipation characteristics. Each installation direction has its own optimized temperature threshold that reflects the specific heat dissipation capability in that orientation, allowing the system to operate at optimal temperatures under natural convection conditions.
4Measurement precision
If direction-specific designs are created, then over-temperature protection precision is improved, but device complexity is increased
Solution Approach 1:
The patent introduces a direction detection module as an intermediary that automatically identifies the installation orientation and triggers the appropriate temperature threshold configuration. This intermediary component simplifies the overall system by automatically handling the complexity of direction-specific parameters without requiring manual configuration or multiple dedicated designs for each direction.
