Two-Sided Floor Grinding Disk Mounting Against Diamond Disk Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor conditioning devices face safety risks and damage due to the unreliable attachment of diamond disks, which can detach during high-speed operation, especially when using adhesive methods like glue or sticker tape, compromising both safety and functionality.
Innovation Solution
A two-sided fastening system using a fastening frame on the front and an auxiliary frame on the back of the tool instrument, with anchoring and retaining means, ensures secure and reliable attachment of diamond disks without risking detachment during grinding, utilizing elastic/flexible materials and quick-release mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If diamond disks are attached to the washing disk using adhesive methods like glue or sticker tape, then the attachment process is simple, but the diamond disks may detach during high-speed operation, creating safety risks
Solution Approach 1:
The attachment system is divided into multiple independent components: a fastening frame with fastening elements, an auxiliary frame with retaining elements, and the diamond disk itself. This segmentation allows each component to perform its specific function - the fastening frame provides initial attachment, the auxiliary frame provides retention, and together they create a reliable multi-stage securing system that prevents detachment during high-speed operation while maintaining ease of assembly and removal
Solution Approach 2:
The auxiliary frame is positioned to surround and nest within the fastening frame, creating a nested structure where the auxiliary frame's retaining elements work in conjunction with the fastening frame's fastening elements. This nested arrangement provides layered protection and multiple retention points, significantly enhancing attachment reliability while allowing the entire assembly to be easily installed and removed as a unit
2Reliability
If the diamond disk is securely attached to prevent detachment, then work safety is improved, but the attachment structure becomes more complex
Solution Approach 1:
The attachment system is divided into modular components - a fastening frame with fastening elements and an auxiliary frame with retaining elements - that can be manufactured using standard fabrication processes. This segmentation allows each component to be simple in itself while collectively providing robust safety, and enables easy assembly and maintenance without requiring complex integrated structures
Solution Approach 2:
The fastening frame and auxiliary frame act as intermediary structures between the washing disk and the diamond disk. These intermediaries provide the secure mechanical connection needed for safety while keeping the actual attachment mechanism relatively simple - using standard fastening and retaining elements rather than complex integrated systems, thus balancing safety requirements with structural simplicity

AI summary
An arrangement for floor grinding with a floor conditioning device. A tool instrument is used in the floor conditioning device by rotating the floor conditioning device. The instrument is an essentially porous washing, polishing, waxing disk for carrying out basic functions of the floor conditioning device. A grinding instrument is removably coupled in connection with the tool instrument. A fastener couples the grinding instrument with the tool instrument by a fastening frame supported on a front surface of the tool instrument and by an auxiliary frame supported on a back surface of the tool instrument.
