Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing portable ground connections in electrical installations require significant physical effort, pose a risk of injury due to the weight of cables and clamps, and can lead to accidents from uncontrolled falls or misplacement, especially at higher heights.
Innovation Solution
A ground connection device with a lightweight first pole and hoisting device that allows for safe and ergonomic installation by using a hook, pulley, and telescopic second pole to minimize physical effort and prevent accidents, featuring a system with a ground connection device, hoisting device, and hoisting rope or cable for secure and efficient grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional poles are used to lift and place ground connections, then the grounding process is quick and widely used, but the operator must support the substantial weight of the clamp and GRD braid, requiring practice and skill
Solution Approach 1:
A lightweight telescopic pole with pulley system serves as an intermediary tool. The pole itself weighs only 0.65 kg and includes a pulley mechanism that allows the ground connection to be hoisted using rope, eliminating the need for the operator to directly support the full weight of the clamp and braid while maintaining operational speed
2Ease of operation
If ropes are used to lift the heavy elements of the ground connection, then physical effort is reduced and safety is improved, but the installation and removal process becomes slower and more complex
Solution Approach 1:
The invention merges the advantages of both conventional poles and rope systems by integrating a pulley mechanism into a lightweight telescopic pole. This combination allows the ground connection to be hoisted using rope (reducing physical effort) while maintaining a simple, quick操作流程 similar to conventional pole methods
3Length of stationary object
If the height of the connection point is increased, then more coverage is achieved, but the demand and risk of the activity increases, and the operator may lose balance and fall
Solution Approach 1:
The lightweight pole design (0.65 kg) acts as a counterbalance that eliminates the weight instability problem. The pole is light enough that the operator can control it easily at heights up to 7 meters without losing balance, yet sufficiently rigid to perform the grounding operation effectively

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 system reduces muscular-skeletal risk for operators, prevents damage to switchgear, and minimizes the risk of accidents by ensuring controlled and secure fixing of grounding clamps, allowing for safe and efficient grounding at heights up to 7 meters without wear on hoisting ropes.
