Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices such as smartphones and wearable devices face high energy consumption, leading to reduced endurance time without compromising performance, as existing solutions often require power-saving modes that affect user experience.
Innovation Solution
A motor module integrated into the device generates electrical energy during motion, providing a motion charging function by using a coil and magnetic object within a housing, allowing the device to charge its power supply without increasing space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the device uses power-saving modes to extend endurance time, then the duration of action is improved, but the performance and user experience deteriorate
Solution Approach 1:
The patent combines the motor function and power generation function into a single motor module. The motor module can operate in two states: motor state where the coil drives the magnetic object to move, and power generation state where the magnetic object moves to generate charging current. This merging allows the device to extend endurance time without entering power-saving modes, maintaining full performance and user experience.
Solution Approach 2:
The motor module enables the device to generate its own charging current through the movement of the magnetic object within the coil. This self-service mechanism allows the device to recharge itself during operation, extending endurance time without external power sources or performance degradation.
2Duration of action of moving object
If a separate power generation module is added to extend endurance, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the power generation function into the existing motor module structure. The motor module includes a housing, a coil surrounding the housing, and a magnetic object disposed in the housing. The same components used for motor function (coil, magnetic object, housing) are utilized for power generation, eliminating the need for separate power generation modules and reducing device complexity.
Solution Approach 2:
The motor module is designed to perform multiple functions: it can operate as a motor to drive the magnetic object, and it can operate as a generator when the magnetic object moves within the coil. This multi-functionality allows a single module to extend endurance time without increasing device complexity through additional components.
