Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the muffler is supported asymmetrically on the engine or engine frame through the intake part and exhaust part, then the exhaust gas can be discharged effectively, but the vibration generated in the engine is asymmetrically transferred to the muffler, causing damage or breakage
Solution Approach 1:
The patent applies asymmetry principle by intentionally introducing a symmetric support structure to counteract the existing asymmetric vibration problem. The symmetric support structure includes symmetrically arranged support rods and support plates that provide balanced support to the muffler, thereby reducing asymmetric vibration transfer from the engine while maintaining effective exhaust gas discharge.
Solution Approach 2:
The patent employs beforehand cushioning by incorporating vibration isolation measures in advance through the symmetric support structure. The support rods and support plates are designed to provide cushioning effects before vibration damage can occur, protecting the muffler and connected parts from asymmetric vibration-induced damage during operation.
2Stability of the object's composition
If the intake part and exhaust part are coupled to the engine or engine frame to support the muffler, then the exhaust apparatus is stable, but asymmetric vibration is transmitted causing damage to the muffler, intake part, and exhaust part
Solution Approach 1:
The patent uses asymmetry principle by implementing a symmetric support structure to balance the asymmetric forces acting on the exhaust apparatus. The symmetric arrangement of support rods and support plates creates a balanced support system that reduces asymmetric vibration transmission while maintaining overall structural stability.
Solution Approach 2:
The symmetric support structure acts as an intermediary between the engine and the muffler. The support rods and support plates serve as intermediate elements that decouple the direct asymmetric connection, providing a buffer that reduces vibration transmission while maintaining structural stability.
3Productivity
If the muffler is supported on the engine or engine frame through asymmetric support structures, then the exhaust gas flow is maintained, but the asymmetric vibration causes damage or breakage at vulnerable coupling points
Solution Approach 1:
The patent applies asymmetry principle by introducing a symmetric support structure to counterbalance the asymmetric vibration problem. The symmetric arrangement of support rods and support plates provides balanced support that maintains exhaust gas flow while reducing asymmetric vibration transmission to vulnerable coupling points.
Solution Approach 2:
The symmetric support structure provides beforehand cushioning by preemptively reducing vibration stresses at coupling points before damage can occur. The support rods and support plates are designed to distribute and dampen vibrations, protecting vulnerable areas from fatigue and failure during normal operation.
