Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible screen is folded into a totally folded state, then the device becomes more compact and portable, but the flexible screen becomes vulnerable to damage
Solution Approach 1:
The bellows structure is designed with a receiving space that can be filled with buffer material (such as foam or air) to cushion and protect the flexible screen during folding. The micropore structure on the bellows surface allows air to enter and fill the receiving space, creating a protective cushion before the screen is subjected to folding stress.
Solution Approach 2:
The bellows structure acts as a flexible protective shell that encloses the flexible screen during folding. The bellows can expand and contract while maintaining protection, and its flexible nature allows it to accommodate the screen's movement without rigid constraints that could cause damage.
2Stability of the object's composition
If the flexible screen is folded at specific angles, then the device can maintain stable structural support, but the folding mechanism becomes more complex
Solution Approach 1:
The magnetic strip units are arranged on the bellows structure and screen terminal portions to automatically attract and hold the folded device at specific angles. The magnetic attraction provides self-stabilizing support without requiring external actuators or complex locking mechanisms, allowing the device to maintain stable folded states through inherent magnetic forces.
3Object-affected harmful factors
If the bellows structure is sealed to protect internal components, then environmental protection is improved, but air ventilation is restricted
Solution Approach 1:
The bellows structure incorporates a micropore structure on its surface that allows selective permeability. The micropores are small enough to block liquid and dust particles while large enough to allow air molecules to pass through. This enables the bellows to maintain environmental protection against liquids and contaminants while providing necessary air ventilation for internal components.
