Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a protective shell with fixed supporting structure is used, then the structure is simple and easy to manufacture, but the supporting angle is limited and aesthetics are poor
Solution Approach 1:
The supporting plate is designed to rotate relative to the shell body around a vertical axis, transforming the fixed supporting structure into a dynamic one. This rotation mechanism enables the supporting plate to achieve 360° angle adjustment, allowing the holder to adapt to various supporting angles and scenarios while maintaining a relatively simple overall structure
Solution Approach 2:
The holder is divided into distinct functional modules: the shell body, the rotatable supporting plate, the supporting frame, and the angle limiter. This segmentation allows each component to perform its specific function independently while contributing to the overall versatility, particularly the supporting plate's rotation capability that enables multiple supporting angles
2Adaptability or versatility
If a simple protective shell structure is used, then it is easy to manufacture, but it has poor aesthetics and limited functionality
Solution Approach 1:
The holder integrates multiple functions into a single device: protection (shell body), angle adjustment (rotatable supporting plate), angle limitation (angle limiter mechanism), and aesthetic lighting (light emitting member). This multi-functionality allows the holder to adapt to various usage scenarios including different supporting angles and providing both protection and aesthetic value without requiring multiple separate components
3Adaptability or versatility
If the supporting plate can rotate 360°, then it adapts to more supporting angles, but it becomes difficult to maintain stable rotation angles
Solution Approach 1:
The angle limiter mechanism provides mechanical feedback to the supporting plate's rotation. As the supporting plate rotates, the angle limiter structure interacts with it to prevent rotation beyond predetermined angle ranges, giving the user tactile feedback and automatically maintaining stable rotation angles without requiring active control systems
Solution Approach 2:
The angle limiter acts as an intermediary mechanism between the user's rotation action and the supporting plate's final position. It mediates the rotation process by providing mechanical constraints that guide the supporting plate to stable angular positions while still allowing 360° rotation capability within safe ranges
4Illumination intensity
If a light emitting member is added to improve aesthetics, then the appearance is enhanced, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical switching mechanisms with a magnetic field-based Hall switch system. The Hall switch detects the position of a magnetic member on the supporting plate to control the light emitting member's on/off state, eliminating the need for mechanical switches or complex circuitry while maintaining aesthetic lighting functionality
Applied Scientific Principles

Function Achieved in This Case
The holder provides versatile angle support, improved aesthetics through lighting, and convenience with a battery compartment and stylus holder, enhancing user experience.
Implementation Method 1
the circuit board is provided with a Hall switch... When the supporting plate rotates, the magnetic member approaches or moves away from the Hall switch, so that the Hall switch is turned on or off

AI summary
A mobile terminal protective holder includes a shell body, a supporting plate, a supporting frame, an angle limiter, and a circuit board. Electronic products such as mobile terminals are arranged in an accommodating cavity of the shell body, and the supporting frame is rotatable with the supporting plate around an axis. A Hall switch and a light emitting member are provided on the circuit board. A magnetic member is provided on the supporting plate. When the supporting plate rotates, the magnetic member approaches or moves away from the Hall switch, thereby controlling the connection and disconnection of the Hall switch.
