Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of full screen displays in mobile phones reduces the internal space available for functional modules, making it challenging to accommodate them effectively.
Innovation Solution
A functional assembly that includes a motor-driven shaft system with a linking mechanism, allowing the functional module to rotate along a first axis while keeping the motor's second axis away from the device's frame, thereby reducing the device's thickness and enabling multiple functional modes without increasing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a full screen display is used, then the display area is improved, but the internal space for functional modules is reduced
Solution Approach 1:
The patent positions the motor's rotation axis away from the device frame, utilizing the third dimension (depth/thickness direction) to resolve the spatial conflict. By orienting the motor axis parallel to but separated from the frame, the functional module can rotate to access different functional positions without increasing the device's overall thickness, thus maintaining full-screen display area while providing adequate internal space for functional modules.
2Power
If the motor size is increased, then the driving capability is improved, but the device thickness is increased
Solution Approach 1:
The patent resolves the thickness conflict by reorienting the motor's rotation axis to be parallel to the device frame rather than perpendicular. This dimensional reconfiguration allows the motor to be positioned away from the frame, utilizing the lateral space instead of the thickness direction. The functional module rotates along this reconfigured axis, enabling sufficient driving capability for multiple functional positions without increasing device thickness.
3Volume of stationary object
If the functional module is positioned closer to the frame, then the space utilization is improved, but the motor positioning becomes constrained
Solution Approach 1:
The patent simplifies motor positioning by establishing the rotation axis parallel to the device frame rather than perpendicular. This reconfiguration creates independent spatial zones: the functional module can be positioned close to the frame for optimal space utilization, while the motor is positioned away from the frame along the same axis. The linking mechanism connects these separated components, reducing positioning constraints and simplifying the overall structural arrangement.

AI summary
A functional assembly and an electronic device including the functional assembly are provided. The functional assembly includes a functional module, a motor, and a linking mechanism. The functional module has a first shaft. The motor has a second shaft and is configured to drive the second shaft to rotate. The linking mechanism is connected with the first shaft and the second shaft such that the first shaft and the second shaft are linking-up with each other. As a result, the thickness of the electronic device near the frame is not limited by the size of the motor, which further reduces the thickness of the electronic device.
