Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lighting unit is made with rigid materials to maintain structural stability, then strength and stability are improved, but the ability to adapt to geometric changes and deformations deteriorates
Solution Approach 1:
The lighting unit employs different materials with different deformation characteristics in different regions: the profile element uses a first material that deforms more easily, while the base part uses a second material that deforms less. This local differentiation allows the unit to adapt to geometric changes through the profile element while maintaining overall structural stability through the base part.
Solution Approach 2:
The lighting unit is constructed as a composite structure combining two different materials: a first material for the profile element that offers less resistance to deformation, and a second material for the base part that offers greater resistance to deformation. This composite approach enables the unit to simultaneously achieve adaptability and structural stability.
2Shape
If the lighting unit is designed with a U-shaped profile element for aesthetic appearance, then shape and aesthetics are improved, but resistance to deformation deteriorates
Solution Approach 1:
The U-shaped profile element is specifically designed with a first material that offers less resistance to deformation, allowing it to flex and adapt to geometric changes while maintaining its aesthetic U-shape. The base part uses a second material with greater deformation resistance to provide structural support.
Solution Approach 2:
The invention changes the material parameter (deformation resistance) of the profile element to be lower than that of the base part. This parameter differentiation allows the profile element to deform more easily, accommodating geometric changes while preserving the aesthetic U-shaped design.
3Adaptability or versatility
If the lighting unit is made more flexible to adapt to deformations, then adaptability is improved, but structural strength deteriorates
Solution Approach 1:
Different regions of the lighting unit have different material properties: the profile element uses a first material with lower deformation resistance for flexibility and adaptability, while the base part uses a second material with higher deformation resistance for structural strength.
Solution Approach 2:
The lighting unit combines two materials with complementary properties: a softer first material in the profile element for flexibility and a stronger second material in the base part for structural integrity. This composite construction resolves the contradiction between flexibility and strength.
