Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage transformer line routing systems face mechanical strength limitations due to increasing voltage demands, as traditional screw connections reach their load capacity, necessitating a more robust and cost-effective solution for securing the cable routing.
Innovation Solution
A support structure with a wedge-shaped clamping mechanism and compensating elements, replacing traditional screw connections, provides enhanced mechanical strength and secure holding of the cable routing by adjusting the clamping force through a movable clamping wedge and securing plate, ensuring the cable routing is firmly attached to the support frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional screw connections are used to secure the cable routing, then the device structure is simple and easy to manufacture, but the mechanical strength reaches a load capacity limit and cannot meet increasing voltage requirements
Solution Approach 1:
The clamping wedge is designed to be movable rather than fixed, allowing it to be positioned and secured at different locations along the support frame. This dynamic element enables adjustable clamping force distribution, providing enhanced mechanical strength while maintaining a relatively simple structure that can be manufactured cost-effectively.
Solution Approach 2:
The clamping force parameter can be varied by changing the position of the clamping wedge along the support frame. This allows the mechanical strength to be optimized for different voltage requirements and cable routing configurations without changing the basic structure, thus maintaining ease of manufacture while achieving the required strength.
2Reliability
If the cable routing is designed to be more spacious to meet increasing voltage requirements, then the electrical insulation is improved, but the device size and structural complexity increase
Solution Approach 1:
The support frame is divided into multiple support stands that can be independently positioned, allowing the cable routing space to be segmented and optimized for electrical insulation requirements. Each support stand can be adjusted to create appropriate spacing and insulation distances without requiring a complete redesign of the entire structure, thus limiting the increase in overall device complexity.
3Strength
If the clamping wedge is made movable to enable adjustment of clamping force, then the holding force is optimized, but the device complexity increases due to additional components
Solution Approach 1:
The securing plate acts as an intermediary element between the clamping wedge and the support frame. It provides a simple interface for securing the movable clamping wedge at different positions without requiring complex locking mechanisms or additional components, thus enabling optimized holding force while minimizing the increase in device complexity.
