Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a support crosspiece is designed with high rigidity to reduce vibrations and noise in internal combustion engine vehicles, then vibration damping performance is improved, but the weight and complexity of the component increases
Solution Approach 1:
The support crosspiece is divided into a modular structure consisting of a base crosspiece and an optional stiffening structure that can be separately installed. This segmentation allows the vehicle manufacturer to choose the appropriate configuration based on the specific vehicle model's vibration requirements, without unnecessarily increasing weight on all vehicles.
Solution Approach 2:
The support crosspiece design allows for dynamic configuration where the stiffening structure can be selectively added or removed based on the vehicle type. Electric vehicle models use the lighter base configuration, while internal combustion engine models use the enhanced stiffened configuration, optimizing weight for each application.
2Object-affected harmful factors
If the support crosspiece is designed with model-specific modifications to optimize performance for different vehicle types, then vibration control is improved, but the manufacturing cost and complexity increases
Solution Approach 1:
The base support crosspiece is designed as a universal component that can be used across all vehicle models. The optional stiffening structure serves multiple functions by being adaptable to different vehicle types, allowing the same basic component design to serve both electric and internal combustion engine vehicles with minimal modification.
Solution Approach 2:
The patent establishes a preliminary base crosspiece design that is optimized for electric vehicles, and provides a standardized stiffening structure that can be pre-fabricated and optionally added for internal combustion engine models. This preliminary action reduces manufacturing complexity by establishing a common platform before model-specific adaptations are needed.
3Strength
If a stiffer support crosspiece structure is used to reduce dashboard vibrations, then structural rigidity is improved, but the adjustment range of the steering column is reduced
Solution Approach 1:
The stiffening structure is applied locally to specific portions of the support crosspiece where vibration control is most needed, rather than making the entire structure uniformly stiff. This localized approach maintains structural rigidity in critical areas while preserving flexibility and adjustment range in other areas where steering column movement is required.
