Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large grounding segment is used, then the grounding connection is stable, but the excavation area increases and environmental protection is compromised
Solution Approach 1:
The grounding segment is divided into multiple smaller segment single bodies that can be connected together. Each segment single body has a size suitable for minimal excavation, while multiple segments can be assembled to achieve the required grounding connection stability. The locking apparatus connects these segments to form a complete grounding segment with adequate mechanical strength and electrical continuity.
2Device complexity
If a fixed-size grounding segment is used, then the structure is simple, but it cannot adapt to grounding conductors of different sizes, reducing universality
Solution Approach 1:
The curved fixing member is designed as a movable component that can adjust its position and shape along the chute. When the locking apparatus is tightened, the curved fixing member deforms and moves to adapt to different conductor diameters. This dynamic adjustment mechanism allows the grounding segment to universally fit various conductor sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The curved fixing member changes its geometric parameters (position, deformation degree) in response to different conductor sizes. The elastic member provides the necessary force for this parameter change, allowing the fixing member to conform to conductors with different diameters. This parameter adaptation enables universality without significantly complicating the structure.
3Adaptability or versatility
If a segmented grounding device with adjustment mechanism is used, then universality improves, but the device complexity increases
Solution Approach 1:
The slider is nested within the chute, and the curved fixing member is nested within the segment single body structure. This nested arrangement allows the adjustment mechanism to be compact and integrated into the overall structure rather than adding external complexity. The components fit within each other, maintaining a relatively simple device configuration while achieving universality.
4Reliability
If a large grounding segment is transported and installed, then the grounding connection is reliable, but the transportation and mounting workload increases
Solution Approach 1:
The grounding segment is segmented into multiple smaller segment single bodies that are easier to transport and handle individually. The locking apparatus enables quick assembly of these segments into a complete grounding segment with reliable connection. This segmentation reduces transportation and mounting workload while maintaining grounding connection reliability through the locking mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for convenient transportation and mounting, reduces excavation workload, and enhances the grounding segment's ability to fit different conductor sizes, improving both environmental impact and reliability.
Implementation Method 1
The interior of the chute is in sliding connection with an elastic member; two ends of the elastic member are respectively connected to sliders; the sliders are in sliding connection with the interior of the chute
Implementation Method 2
as the locking apparatus is tightened, the curved fixing member and the grounding conductor mutually squeeze each other, thereby causing the curved fixing member to deform gradually
