Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cowl crossbar is mounted in the vehicle body length direction to maximize internal space, then the internal space is increased, but the connectivity in the vehicle body width direction deteriorates
Solution Approach 1:
The patent introduces a cowl crossbar mounting structure that acts as an intermediary component between the cowl crossbar and the vehicle body. This mounting structure provides connection portions that extend in the vehicle body width direction, enabling connectivity without requiring the cowl crossbar itself to extend in that direction. The mounting structure mediates the connection while maintaining the simplified longitudinal configuration.
Solution Approach 2:
The patent resolves the connectivity issue by transitioning from a longitudinal connection approach to a transverse connection approach. The mounting structure includes connection portions that extend in the vehicle body width direction (transverse dimension), allowing the cowl crossbar to maintain its longitudinal orientation while achieving width-direction connectivity through the mounting structure's transverse elements.
2Volume of moving object
If the cowl crossbar is mounted in the vehicle body length direction, then space for electronic equipment can be secured, but Ride and Handling performance deteriorates due to lack of connectivity
Solution Approach 1:
The mounting structure serves as an intermediary that decouples the cowl crossbar's longitudinal configuration from the connectivity requirements. The connection portions extending in the width direction provide the necessary structural connectivity for Ride and Handling performance while allowing the cowl crossbar to maintain its space-efficient longitudinal arrangement.
Solution Approach 2:
The patent divides the mounting function into separate components: the cowl crossbar itself (providing space) and the mounting structure with connection portions (providing connectivity). This segmentation allows each component to optimize its function independently - the cowl crossbar maximizes space while the mounting structure ensures structural connectivity for Ride and Handling.
3Volume of moving object
If the cowl crossbar is mounted in the vehicle body length direction, then internal space is maximized, but watertight performance deteriorates due to complicated sealer line
Solution Approach 1:
The mounting structure acts as an intermediary sealing element between the cowl crossbar and the vehicle body. By providing a standardized mounting interface with connection portions, it simplifies the sealing path compared to direct longitudinal mounting, reducing sealer line complexity while maintaining the space-maximizing longitudinal configuration.
4Length of moving object
If the cowl crossbar is mounted in the T direction (vehicle body length direction), then the opening flange can be positioned forward, but the space behind the mounting part is wasted
Solution Approach 1:
The patent utilizes the vehicle body width direction (transverse dimension) through the mounting structure's connection portions to achieve connectivity, which allows the longitudinal space behind the mounting part to be effectively utilized. This dimensional transition enables better space utilization compared to traditional longitudinal mounting approaches.
