Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices with rotationally driven working tools face significant challenges in efficiently and quickly replacing multiple working tools, as current designs require complex disassembly and specialized tools, leading to increased maintenance time and wear on components.
Innovation Solution
The implementation of a clamping system with form-fitting receiving pockets and clamping elements that allow for easy tool exchange by releasing clamping means and lifting one clamping element from another, eliminating the need for specialized tools and reducing wear on working tools by eliminating the need for bores and threads, while ensuring secure attachment during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If working tools are secured with screws and nuts to the drive shaft, then the attachment is secure during operation, but the tool replacement process becomes complex and time-consuming
Solution Approach 1:
The clamping element is divided into two parts: a first clamping element that forms part of the receiving pocket and a second clamping element that can be moved relative to the first. This segmentation allows the tool to be quickly released by moving only the second clamping element, while the first clamping element remains fixed to maintain structural integrity during operation.
Solution Approach 2:
The second clamping element is designed to be movable relative to the first clamping element, transforming the static fastening system into a dynamic one. This allows the tool to transition between a securely clamped state during operation and a quickly releasable state during replacement, resolving the contradiction between secure attachment and easy replacement.
2Reliability
If specialized tools are used to secure working tools, then the attachment is reliable, but the replacement process requires special tools and increases complexity
Solution Approach 1:
The clamping system is designed to be self-servicing, allowing operators to replace tools using only the built-in clamping mechanism without requiring external specialized tools. The second clamping element can be manually moved to release the tool, making the system easy to operate and maintain while ensuring reliable attachment during normal operation.
3Strength
If working tools have bores and threads for secure mounting, then the attachment is strong, but the production costs increase and wear on components increases
Solution Approach 1:
The clamping element, particularly the second clamping element, is designed as a simpler, more economical component that can be easily replaced or adjusted. This eliminates the need for complex bores and threads in the working tools themselves, reducing manufacturing costs and material usage while maintaining sufficient mounting strength through the clamping mechanism.
4Area of stationary object
If multiple working tools are attached to the rotary table, then the cleaning coverage is improved, but the time required to replace multiple tools increases significantly
Solution Approach 1:
Each working tool is equipped with its own independent clamping system consisting of first and second clamping elements. This segmentation allows individual tools to be replaced independently and quickly without affecting other tools, enabling operators to replace multiple tools efficiently across the entire rotary table while maintaining comprehensive cleaning coverage.
