Caster Wheel Foreign Substance Removal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional casters are inconvenient to assemble and inefficient in removing foreign substances from their wheels, as the roll brush requires manual fixing and rotation, and may not effectively collect substances attached to the outer surface, leading to indoor contamination when used outdoors.
Innovation Solution
A caster design featuring a foreign substance removal device fixed to a rotating shaft, with a brush and accommodation box that automatically collects and discharges foreign substances, using a rotating mechanism and support plate to prevent falling debris and guide substances into the collection area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a roll brush is rotatably installed to pivot arms for removing foreign substances, then foreign substances can be removed from the wheel surface, but the device becomes inconvenient to assemble because both ends of the shaft need to be fastened using nuts
Solution Approach 1:
The caster is divided into modular components: a removable foreign substance removal device that can be detached from the main body, and a separate shaft assembly. This segmentation allows the removal device to be easily attached and detached without complex fastening operations, resolving the assembly convenience issue while maintaining the foreign substance removal function.
Solution Approach 2:
The foreign substance removal device is extracted as a separate, removable module from the caster body. It can be detached when not needed and easily reattached, eliminating the need for permanent fastening with nuts and bolts. This extraction principle maintains the removal function while significantly improving assembly convenience.
2Use of energy by moving object
If the roll brush is rotated via the rotation of the wheel, then the brush can be driven without additional power source, but the foreign substances cannot be easily removed and collected from the wheel surface
Solution Approach 1:
The brush configuration is made dynamic rather than static. The brush members are arranged to rotate with the wheel, creating a dynamic cleaning action that effectively removes foreign substances. This dynamic configuration, combined with the angled arrangement of brushes, ensures both energy efficiency and effective foreign substance removal and collection.
Solution Approach 2:
The brush members are arranged at specific angles relative to the wheel surface, adding a dimensional component to the cleaning action. This angular arrangement ensures that the rotating brushes can effectively engage with and remove foreign substances from the wheel surface, improving collection efficiency while maintaining passive rotation.
3Adaptability or versatility
If the caster is used outdoors, then it can perform its transportation function, but a large amount of foreign substances becomes attached to the wheel and may be introduced indoors causing contamination
Solution Approach 1:
The foreign substance removal device performs preliminary cleaning action on the wheel surface before the caster enters indoor environments. By proactively removing foreign substances accumulated during outdoor use, the device prevents contamination of indoor spaces, allowing the caster to maintain both outdoor versatility and indoor cleanliness.
Solution Approach 2:
The foreign substances that accumulate on the wheel during outdoor use are converted from a harmful contaminant into a manageable condition. The removal device captures and collects these substances, transforming the potential indoor contamination problem into a controlled collection process that protects indoor environments while maintaining outdoor operational capability.
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 caster automatically removes and collects foreign substances from its wheel surface, preventing indoor contamination by using a rotating mechanism and support plate to efficiently guide and collect debris, enhancing usability and cleanliness.
Implementation Method 1
a return spring (74), which serves to rotate the accommodation box (72) back and remain at an initial position thereof using a restoring force generated by elastic force
Implementation Method 2
a brush (73), which serves to remove the foreign substance attached to the wheel (50)
