Suspended Rechargeable Power Tool With Dock Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial tools used in automobiles and aeronautics, such as screwdrivers, are hindered by the weight and rigidity of suspension cables and electrical cables, which reduce flexibility and increase costs, while existing solutions either fail to provide adequate weight compensation or communication with controllers.
Innovation Solution
A portable tool system with a motor-driven mechanism and inductive or contact-based energy transmission link that charges the tool when it is on a support, allowing for weight reduction and easy handling, while maintaining communication with a controller for operation and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suspension cable and electrical cable are used to power and suspend the tool, then the tool can be suspended at height and powered during operation, but the flexibility of the system is reduced and handling is hampered
Solution Approach 1:
The invention extracts the electrical cable from the suspension system by using a purely mechanical suspension cable that only supports the tool weight. The electrical connection is established separately through a connection element on the support, eliminating the need for a combined cable and restoring system flexibility and ease of handling.
2Device complexity
If an electrical cable is used to suspend the tool, then the tool can be suspended without a separate cable, but the cable section becomes substantial and rigid making the tool difficult to handle
Solution Approach 1:
The invention segments the suspension and electrical connection functions into separate components: a thin mechanical suspension cable for weight support and a separate connection element for electrical power. This segmentation allows the suspension cable to remain flexible and maneuverable while still providing electrical connection capability.
3Device complexity
If a substantial electrical cable is used for suspension, then the tool can be suspended, but the cable becomes very costly
Solution Approach 1:
The invention divides the system into a simple mechanical suspension cable and a separate electrical connection element. This segmentation allows each component to be optimized independently, using a thin, inexpensive cable for suspension and a dedicated connection element for power, thereby reducing overall system cost.
4Ease of operation
If the tool is suspended at height with a weight-compensating device, then the operator's movements are not hampered, but the tool requires a substantial cable system that reduces flexibility
Solution Approach 1:
The invention extracts the electrical connection function from the suspension cable system. A simple mechanical cable provides weight compensation and freedom of movement, while a separate connection element on the support provides electrical power without adding cable complexity or reducing flexibility.
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 system effectively lightens the tool for easier handling and reduces costs by eliminating the need for metal contacts and electromagnetic disturbances, while ensuring reliable energy transfer and operation control.
Implementation Method 1
a winding apparatus of said line exerting a vertical tension to the tool so as to lighten a weight of the tool
Implementation Method 2

AI summary
An industrial device including a portable tool and a support for this tool. The tool is provided with a motor driving a mechanism in rotation, an electrical energy store to power the tool during operation and a controller to control the motor. The support includes a line, one extremity of which is affixed to the tool, a receiving element defining a location for the grasping of the tool and a winding apparatus of said line exerting a vertical tension to the tool so as to lighten its weight when it is no longer at its grasping location. The industrial device further includes a transmission of an electrical energy to charge the energy store when the tool is positioned in the receiving element. The tool is light weight tool while at the same time highly maneuverable in charging supercapacitors or a battery only when the tool is on the support.
