Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional materials and structures are used in mobile communication devices, then manufacturing is easier and cost is lower, but the device lacks durability and rigidity
Solution Approach 1:
The patent applies composite materials by combining magnesium alloy with plastic components to create a chassis that achieves both durability and ease of manufacture. The magnesium alloy provides strength and rigidity while the plastic components allow for cost-effective manufacturing and assembly.
Solution Approach 2:
The chassis is segmented into multiple components including magnesium alloy plates, plastic housings, and internal support structures. This segmentation allows each component to be optimized for its specific function while simplifying manufacturing and assembly processes.
2Length of moving object
If device thickness is reduced for portability, then ease of carrying improves, but structural strength and protection decrease
Solution Approach 1:
The patent applies local quality by strategically placing magnesium alloy plates and internal support structures in specific areas of the device where strength is most needed, such as around the display and keypad areas. This allows the device to maintain thin overall dimensions while providing localized structural reinforcement.
Solution Approach 2:
The combination of magnesium alloy and plastic materials enables the creation of a thin yet strong structure. The magnesium alloy provides high strength-to-weight ratio allowing thin design, while the plastic components provide additional protection and cushioning.
3Volume of moving object
If device size is reduced for portability, then ease of carrying improves, but functionality and battery capacity are limited
Solution Approach 1:
The patent employs parameter changes by utilizing advanced magnesium alloy materials with superior strength-to-weight ratios, allowing reduction of device volume while maintaining structural integrity. The optimized material properties enable thinner walls and more compact internal arrangements, preserving functionality in a smaller form factor.
4Reliability
If conventional antenna design is used, then manufacturing is simpler, but the antenna is prone to bending and breaking
Solution Approach 1:
The antenna structure utilizes composite materials combining rigid support elements with flexible connecting portions. This composite construction provides both durability against bending and breaking while maintaining a relatively simple overall antenna design that integrates well with the device housing.
