Floor Grinding Disk Fastening for Secure Diamond Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor grinding devices face safety risks due to the detachment of diamond disks at high speeds, especially when attached using adhesive methods like glue or sticker tape, which can lead to accidents and damage.
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 using adhesive methods like glue or sticker tape, then the attachment process is simple, but the diamond disks may detach at high speeds causing safety risks
Solution Approach 1:
The patent replaces adhesive attachment methods with a mechanical fastening system consisting of a fastening frame and auxiliary frame that clamp the diamond disk against the tool instrument. This mechanical system provides reliable retention at high rotation speeds while maintaining ease of attachment and removal through the designed fastening mechanism.
Solution Approach 2:
The fastening system is divided into separate components: a fastening frame with retaining means, an auxiliary frame, and anchoring means. This segmentation allows for easy assembly and disassembly of the diamond disk while ensuring secure attachment during operation, resolving the contradiction between simple attachment and reliable retention.
2Reliability
If diamond disks are securely fastened to prevent detachment, then work safety is improved, but the device structure becomes more complex
Solution Approach 1:
The fastening frame and auxiliary frame are designed to work together as an integrated system that clamps the diamond disk from both sides. This merging of components creates a robust safety mechanism without requiring excessive individual parts, achieving high reliability while controlling structural complexity.
Solution Approach 2:
The fastening system incorporates elastic/flexible material that can deform to accommodate the diamond disk and tool instrument surfaces, then maintains constant retaining pressure. This flexibility simplifies the overall structure compared to rigid mechanical fasteners while ensuring secure attachment and improved work safety.
3Adaptability or versatility
If diamond disks are removably coupled to washing disks, then the washing disk can be reused, but the coupling method must ensure secure attachment during high-speed rotation
Solution Approach 1:
The diamond disk is designed as a separate, removable component that can be easily detached from the washing disk using the fastening system. This extraction approach allows the washing disk to be reused for multiple purposes while the diamond disk can be replaced when worn, maintaining both adaptability and attachment security through the mechanical fastening design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances work safety and efficiency by allowing secure, easy attachment and detachment of diamond disks, preventing accidents and maintaining the functionality of the washing disk, thereby improving floor grinding processes.
Implementation Method 1
The fastening means according to the invention may advantageously be implemented e.g. as a compound structure entirety made of a elastic/flexible material reaching to the opposite sides of the tool instrument
