Suspended Wheel Support for Accurate Marking on Uneven Floors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marking robots face difficulties in maintaining accurate direction and location on uneven or foreign matter-covered floor surfaces due to wheels lifting off, which prevents desired movement and marking work.
Innovation Solution
Incorporating a suspension mechanism in the wheel support parts of the marking robot, specifically with an energizing member and damper, to ensure all wheels remain grounded, allowing for precise movement and accurate marking even on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the marking robot uses mecanum wheels for multi-directional movement, then the robot can move in any direction, but the robot cannot maintain all wheels grounded on uneven floor surfaces, causing loss of control and positioning accuracy
Solution Approach 1:
The wheel support parts are designed to be movable relative to the main body, allowing the support structure to dynamically adjust its position and orientation in response to floor surface variations. This dynamic adaptation ensures that all mecanum wheels remain grounded while maintaining the robot's multi-directional movement capability.
Solution Approach 2:
The robot's support structure is divided into multiple independent wheel support parts, each capable of independent movement and adjustment. This segmentation allows each wheel to independently adapt to local floor conditions while maintaining overall system stability and control.
2Manufacturing precision
If the robot body is kept rigid for stable marking, then marking precision is maintained on flat surfaces, but wheel lift-off occurs on uneven surfaces with foreign matter, preventing desired movement
Solution Approach 1:
The support parts are designed with movable joints and suspension mechanisms that allow them to dynamically adjust to uneven surfaces and foreign matter. This dynamic adaptation prevents wheel lift-off while maintaining the rigidity of the main body and marking unit, ensuring both movement capability and marking precision on challenging surfaces.
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 suspension mechanism ensures all wheels maintain contact with the floor, enabling the marking robot to move accurately in desired directions and perform high-precision marking work on surfaces with foreign matter or irregularities.
Implementation Method 1
the suspension mechanism has first and second bracket members that are pivotally connected to each other via a shock-absorbing member, and have a spring member that elastically connects between the first and second bracket members
