Planar Drive Platform Coupling for Cable-Free Tool Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing planar drive devices require additional power sources for actuating work tools, which can be cumbersome and limit the freedom of tool positioning.
Innovation Solution
The planar drive device employs a drive member and transmission that move in a plane perpendicular to the X-Y plane, allowing the work tool to be actuated through relative movement of the platforms, eliminating the need for additional power supplies by utilizing existing drive energy, and enabling the work tool to be positioned freely in a 3D space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary power source connected via line to the work tool is used, then the work tool can be actuated, but the positioning freedom of the work tool is limited by the power supply line
Solution Approach 1:
The power supply function is extracted from the stationary infrastructure and integrated into the movable platform itself. The platform now carries its own power source and transmission components, eliminating the need for external power lines and enabling free positioning within the workspace.
Solution Approach 2:
The platform is designed to perform multiple functions: it serves as both the mechanical support structure and the power supply unit. By integrating the motor, power source, and transmission mechanisms directly onto the platform, the system achieves multi-functionality without requiring separate power supply infrastructure.
2Ease of operation
If a power store moved together with the working platform is used, then the work tool can be actuated without lines, but the working platform space is occupied by the power store
Solution Approach 1:
Instead of separating the power store as an independent component on the platform, the power source is merged with the drive mechanisms. The motor that drives the platform movement also serves to actuate the work tool through the transmission system, eliminating the need for dedicated power storage space on the platform.
Solution Approach 2:
The drive motor performs dual functions: propelling the platform across the workspace and actuating the work tool through the transmission system. This multi-functionality eliminates the need for separate power store components, preserving working platform space.
3Extent of automation
If additional power supply components are added to actuate the work tool, then the work tool can be actuated, but the device complexity increases
Solution Approach 1:
The drive motor and transmission system are merged into a single integrated mechanism on the platform. The same motor that moves the platform also actuates the work tool through the transmission, eliminating the need for separate power supply components and reducing overall system complexity.
Solution Approach 2:
The transmission system serves multiple purposes: it transmits power for platform movement and simultaneously actuates the work tool. This multi-functional design reduces the number of components needed while maintaining full automation capability.

AI summary
A planar drive device having a first platform and having a second platform, which platforms are movable in an X-Y plane on a work bench, wherein the first platform has a frame, a transmission and a working platform for the arrangement of a work tool, wherein the transmission permits an adjustment of the distance of the working platform with respect to the X-Y plane, wherein the second platform has a frame and a drive member which is coupled in terms of movement at least indirectly to the working platform such that the distance of the working platform from the X-Y plane is adjustable by changing a distance between the two platforms within the X-Y plane. The work tool can be transferred into at least two different working states by relative movement of the platforms in the X-Y plane.
