Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display device is made ultrathin, then the device achieves a sleek and modern design, but the rigidity of the display device deteriorates
Solution Approach 1:
The support structure is divided into multiple recessed portions that extend from the front surface to the rear surface of the inner plate. These segmented recessed portions create multiple coupling areas between the inner plate and main frame, distributing structural support throughout the ultrathin design rather than relying on a single thick section.
Solution Approach 2:
The recessed portions extend in the thickness direction (from front to rear surface), utilizing the third dimension to create structural reinforcement without increasing the overall footprint or average thickness of the display device.
2Volume of moving object
If the display device is made ultrathin, then the device achieves a sleek and modern design, but the heat dissipation capability deteriorates
Solution Approach 1:
The heat dissipation function is segmented into multiple recessed portions distributed across the inner plate. Each recessed portion acts as an independent heat dissipation channel, allowing heat to escape through multiple pathways rather than relying on a single thick section.
Solution Approach 2:
Heat dissipation is achieved by utilizing the thickness direction through recessed portions that extend from front to rear surface. This creates thermal pathways in the third dimension without increasing the device's overall thickness.
3Strength
If complex coupling structures are used to secure rigidity, then the structural strength improves, but the manufacturing complexity and productivity deteriorate
Solution Approach 1:
Multiple functions are merged into the recessed portions: structural coupling between inner plate and main frame, heat dissipation pathways, and laser welding guidance. This consolidation reduces the number of separate components and assembly steps required.
Solution Approach 2:
The recessed portions serve multiple purposes simultaneously: they provide structural reinforcement for rigidity, create heat dissipation channels, and define welding areas for precise laser bonding. This multi-functionality simplifies the overall design and manufacturing process.
