Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a rubber main brush with direct fixed connection is used, then the structure is simple, but the structure is unstable and has poor vibration damping effect
Solution Approach 1:
The main brush is divided into three separate components: a mounting shaft, an elastic supporting member, and a tubular member. These segmented parts are connected through adhesive layers, allowing each component to perform its specific function while contributing to overall structural stability and vibration damping.
Solution Approach 2:
The invention uses composite material construction with the elastic supporting member made of elastic material and the tubular member made of rubber material. The combination of different materials with complementary properties (elasticity and rubber characteristics) creates a structure that is both stable and effective at damping vibrations.
2Ease of manufacture
If a rubber main brush with direct fixed connection is used, then the manufacturing process is simple, but the brush is easily damaged during use
Solution Approach 1:
The elastic supporting member is positioned between the mounting shaft and the tubular member to provide beforehand cushioning. This elastic component absorbs shocks and stresses before they can propagate through the entire brush structure, preventing damage during use while maintaining manufacturing simplicity through the layered assembly process.
3Device complexity
If a rubber main brush with direct fixed connection is used, then the structure is simple, but the vibration damping effect is poor
Solution Approach 1:
The invention changes the physical parameters of the brush structure by introducing an elastic supporting member with specific elastic properties and a tubular member with rubber material characteristics. These parameter changes (material elasticity, structural compliance) enable effective vibration damping while maintaining relative structural simplicity through the modular design.
