Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic transportation systems face challenges in efficiently installing and extending induction power cables due to their heavy and cumbersome nature, which complicates installation and increases the risk of overheating and fires, especially when high-frequency currents are involved.
Innovation Solution
The introduction of a terminal block with an integrated overheating detection unit allows for efficient connection and extension of induction power cables, preventing overheating and fires by automatically detecting and blocking overheated states. Additionally, the terminal block is designed with multiple fixing holes to accommodate pre-cut and lug-treated cables, simplifying installation and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the induction power cable is divided into several strands and connected through a terminal block, then the installation work becomes easy and extension becomes convenient, but overheating may occur due to poor connection of the terminal block when high-frequency current flows
Solution Approach 1:
The terminal block incorporates an overheat detection unit that continuously monitors the temperature of connection parts. When overheating is detected, the system provides feedback to stop power supply, preventing fire accidents. This feedback mechanism resolves the contradiction by enabling easy installation through terminal blocks while eliminating the overheating risk through active monitoring and automatic shutdown.
2Device complexity
If a normal terminal block with one hole is used for fixing cable lug, then the structure is simple, but cable length errors make connection difficult when pre-cut and lug-treated cables are installed
Solution Approach 1:
The terminal block is designed with multiple fixing holes arranged at different positions instead of a single hole. This segmentation allows the cable lug to be connected to any suitable hole, accommodating cable length variations without requiring precise cutting. The structure remains relatively simple while providing multiple connection options that tolerate manufacturing errors.
Solution Approach 2:
The terminal block provides multiple fixing positions (holes) at different locations, changing the spatial parameter of connection points. This allows adaptation to different cable lengths and installation positions, making the connection process easier despite cable length errors while maintaining structural simplicity.
3Stability of the object's composition
If the induction power cable is installed as a long continuous cable, then the induction power track can be formed as a closed loop, but the installation work becomes very difficult and dangerous due to the heavy cable
Solution Approach 1:
The induction power cable is divided into multiple shorter segments that can be individually handled and installed. These segments are then connected through terminal blocks to form a complete closed-loop induction power track. This segmentation makes installation safer and easier by eliminating the need to handle long, heavy continuous cables, while still achieving the required track continuity through proper connection of segments.
