Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If coolers are mounted rigidly on the support bracket, then mounting strength is improved, but replacement difficulty increases
Solution Approach 1:
The patent applies the dynamics principle by using elastic mounting members instead of rigid fixed connections. The elastic members allow the cooler to be mounted securely with sufficient holding strength while enabling easy removal and replacement by simply detaching the mounting members, transforming a permanently fixed structure into a dynamically adjustable one.
Solution Approach 2:
The mounting system is segmented into separate components: the support bracket, the elastic mounting members, and the cooler. This segmentation allows the cooler to be independently removed from the support bracket by detaching the mounting members, facilitating easy replacement while maintaining secure mounting during operation.
2Device complexity
If hydraulic pipes are arranged without sealing structures, then device complexity is reduced, but sealing performance deteriorates
Solution Approach 1:
The patent introduces sealing members as intermediary elements between the hydraulic pipes and the support structures. These sealing members act as mediators that prevent direct contact between the pipes and structural components, ensuring sealing performance while maintaining relative structural simplicity.
Solution Approach 2:
The patent employs flexible sealing members (such as grommets or rubber seals) to seal the hydraulic pipes where they pass through the support bracket or partition structures. These flexible thin film elements conform to the pipe surfaces and provide effective sealing without adding complex rigid sealing mechanisms.
3Device complexity
If the prime mover room is not partitioned from the cooler area, then device complexity is reduced, but cooling performance deteriorates
Solution Approach 1:
The patent segments the machine interior into distinct zones: the prime mover room and the cooler area. A partition structure physically divides these spaces, preventing hot exhaust gases from the prime mover from directly contacting the coolers, thereby maintaining optimal cooling performance through spatial separation.
Solution Approach 2:
The partition structure serves as an intermediary barrier between the hot prime mover environment and the cool cooler area. It blocks thermal transfer and directs cooling airflow appropriately, ensuring that the coolers receive sufficient cool air without direct exposure to prime mover heat.
4Ease of operation
If coolers are cleaned by tilting the frame member, then cleaning access is improved, but foreign matter accumulation increases
Solution Approach 1:
The patent extracts the cooler from its fixed mounted position by providing detachable mounting members. This allows the cooler to be completely removed from the support bracket for cleaning, eliminating the problem of foreign matter accumulation that occurs when coolers are tilted in place, while still providing easy access for maintenance.
