Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual folding and unfolding is used, then the structure is simple, but the screen durability deteriorates and hinge looseness occurs
Solution Approach 1:
The system performs automatic folding and unfolding operations without requiring manual user intervention. The control module automatically triggers the drive assembly to execute folding/unfolding sequences based on predefined conditions, allowing the system to serve itself and eliminating repeated manual stress on the screen and hinge components
Solution Approach 2:
The patent replaces manual mechanical operation with an automated electromechanical system. The drive assembly, comprising a motor and transmission mechanism (gear and rack), substitutes human hand pressure with controlled mechanical actuation, reducing unpredictable manual forces that cause screen damage and hinge loosening
2Ease of operation
If manual folding and unfolding is used, then the device is easy to operate, but screen plane consistency deteriorates
Solution Approach 1:
The control module monitors the folding/unfolding process and adjusts the drive assembly operation to achieve precise screen alignment. By implementing control feedback, the system ensures that screens return to consistent planar positions after each folding cycle, eliminating the sagging and misalignment issues caused by manual operation
Solution Approach 2:
The automated drive assembly replaces manual leveling operations with precision mechanical actuation. The gear-rack transmission mechanism provides controlled, repeatable motion that ensures screens align properly without requiring user intervention for manual adjustment
3Reliability
If automatic folding and unfolding is implemented, then screen durability is improved, but device complexity increases
Solution Approach 1:
The automatic folding mechanism is divided into modular components: a drive assembly with motor, a transmission assembly with gear and rack, and a control module. This segmentation allows each component to perform a specific function independently, making the complex system more manageable and maintainable while achieving automated operation
Solution Approach 2:
The transmission assembly acts as an intermediary between the drive assembly and the screens. The gear-rack mechanism translates rotational motor motion into linear motion that drives the folding operation, providing a mechanical advantage that reduces the complexity of direct drive while protecting the screen from excessive forces
