Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the casing and sensor are integrated with each other, then the mechanical strength is improved, but the number of components to be replaced and the cost are increased
Solution Approach 1:
The casing is divided into multiple separate components: a front member, a back member, and a side member. These members are connected through joining portions that allow them to be separable. This segmentation enables the casing to be disassembled and reassembled, allowing replacement of individual components without replacing the entire integrated structure, thus resolving the contradiction between mechanical strength and ease of repair.
2Weight of moving object
If the radiation imaging apparatus is made thin and lightweight for portability, then the portability is improved, but the mechanical strength to protect internal components is reduced
Solution Approach 1:
The casing members are formed using composite materials, specifically carbon fiber reinforced plastic (CFRP). This material provides high strength-to-weight ratio, enabling the casing to be both lightweight for portability and mechanically strong enough to protect internal components from impact and deformation, thus resolving the contradiction between weight and strength.
Solution Approach 2:
The casing members, particularly the back member, incorporate curved or arc-shaped structures (such as arc-shaped reinforcing members). These curved geometries provide structural reinforcement and impact resistance while maintaining a thin profile, enabling the casing to be both thin/lightweight and mechanically strong.
3Strength
If the thickness is increased at the thread fastening portion to increase rigidity, then the rigidity is improved, but the formability of the component is degraded
Solution Approach 1:
The back member incorporates an arc-shaped reinforcing member with a curved geometry that provides structural rigidity at the fastening portion. The curved shape naturally distributes stress and provides reinforcement without requiring significant increases in thickness, thereby maintaining good formability while achieving the required rigidity.
Solution Approach 2:
The use of carbon fiber reinforced plastic allows the component to achieve high rigidity with thinner sections compared to conventional materials. The composite material's inherent strength enables the fastening portion to maintain rigidity without increasing thickness, preserving formability.
