Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging stations with cable holding devices are complex and costly due to the large number of components required to hold two charging cables effectively, leading to increased operational complexity and potential for cable damage or contamination.
Innovation Solution
A simplified cable holding device using a single cable with a weight element, guided over a first and second deflection device, which maintains a distance between the charging cables and the floor surface, eliminating the need for multiple ropes, suspensions, and partition walls, while allowing for easy cable management and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple ropes, suspensions, and partition walls are used to hold two charging cables, then the cables are kept elevated and protected from ground contact, but the device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple separate cable holding systems into a single integrated cable holding device. Instead of using separate ropes, suspensions, and partition walls for each charging cable, the invention uses one unified mechanism with a single rope and weight element that can hold both charging cables simultaneously, reducing component count while maintaining cable elevation and protection
Solution Approach 2:
The cable holding device is designed to perform multiple functions with a single mechanism. The single rope and weight element system serves to hold both charging cables, maintain their elevation above ground, and provide protection from damage and contamination, replacing what would traditionally require multiple specialized components
2Device complexity
If a single weight element and fewer components are used to hold two charging cables, then the device complexity and cost are reduced, but the ability to maintain cable elevation and prevent ground contact may be compromised
Solution Approach 1:
The patent combines multiple separate cable holding systems into a single integrated cable holding device. Instead of using separate ropes, suspensions, and partition walls for each charging cable, the invention uses one unified mechanism with a single rope and weight element that can hold both charging cables simultaneously, reducing component count while maintaining cable elevation and protection
Solution Approach 2:
The cable holding device uses a weight element that automatically maintains cable elevation through gravity. The system is self-regulating, where the weight element naturally keeps the cables at the required height above ground without requiring additional active control mechanisms or complex adjustment systems
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 reduces complexity and cost by using a single weight element and fewer components, ensuring the charging cables remain elevated and preventing ground contact, thus avoiding damage and contamination, while enabling efficient cable handling and user-friendly insertion of charging plugs.
Implementation Method 1
at least one weight element (124, 126) operatively connected to the rope such that, in an unused state, the charging cables (134, 138) are held in such a way that a gap exists between the ground surface (128) and each part of the charging cables (134, 138)
