Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single liquid crystal display is used, then the device structure is simple, but multiple users cannot view the display comfortably together due to limited viewing angles
Solution Approach 1:
The display system is segmented into two separate displays: a first display on the first body and a second display on the second body. This segmentation allows multiple users to view information from different angles simultaneously, as each display can be independently positioned and viewed, thereby resolving the viewing angle limitation of a single display.
Solution Approach 2:
The patent introduces a spatial dimension by positioning displays on different bodies that can rotate relative to each other. The second body can rotate about a first axis and the third body can rotate about a second axis, creating multiple viewing dimensions and angles, thus enabling comfortable viewing for multiple users simultaneously.
2Ease of operation
If dual displays are added to improve viewing angles, then multiple users can view information comfortably, but the device structure becomes more complex
Solution Approach 1:
The hinge modules serve multiple functions: they provide the rotating mechanism for adjusting display angles, act as structural connectors between bodies, and integrate the switch module for detecting rotation states. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving ease of operation.
Solution Approach 2:
The switch module acts as an intermediary between the hinge module's mechanical rotation and the electronic module activation. It detects the rotation state of the hinge module and translates it into electrical signals to activate appropriate electronic modules, simplifying the control mechanism while enabling convenient user interaction.
3Reliability
If electronic modules are activated based on hinge rotation state, then improper operation can be prevented, but the control mechanism becomes more complex
Solution Approach 1:
The system uses the hinge module's own rotation state to automatically trigger the activation of electronic modules. The switch module detects the physical rotation and autonomously activates the appropriate electronic module without requiring additional sensors or complex control circuits, thereby ensuring reliable operation while minimizing control mechanism complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables multiple users to view information comfortably without angle limitations, provides indication for proper operation, and prevents damage by activating appropriate electronic modules based on the display state, ensuring secure and convenient usage.
Implementation Method 1
The switch module includes a first electrode, a second electrode, a third electrode, and a fourth electrode. The first electrode and the second electrode are separated from each other and fixedly surround a pivot axis of a hinge structure. The third electrode is located on the pivot axis, the fourth electrode pivots about the pivot axis, and the first electrode and the second electrode are located on a pivoting path of the fourth electrode.
