Solution Overview
Problem
The process of incorporating joint material into floor joints is complex and cost-intensive, requiring separate tools and manual labor, especially for single-disc floor grinding machines used for parquet and wooden floors.
Innovation Solution
A plate device for grinding machines, featuring a disk-shaped support plate with sheet metal strip-shaped wing elements that rotate to create a spatula movement and force component, allowing for automatic and cost-effective incorporation of joint material into the floor joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate hand trowel is used for grouting, then the jointing material can be applied to floor joints, but the process becomes time-consuming and requires additional tools
Solution Approach 1:
The patent combines the grinding function and grouting function into a single device. The grinding machine is equipped with a grinding disc that can be replaced by a grouting disc, and a housing that can accommodate both grinding and grouting operations. This merging eliminates the need for separate hand trowels and reduces the number of tools required.
Solution Approach 2:
The grinding machine is designed with multi-functionality to perform both grinding and grouting operations. The device includes a universal housing that can accommodate different disc types (grinding discs and grouting discs) and a drive mechanism that can power both functions, making the machine versatile for different floor treatment tasks.
2Productivity
If manual grouting with a hand trowel is used, then jointing material can be incorporated into floor joints, but the process is time-consuming
Solution Approach 1:
The grouting disc is designed to automatically incorporate jointing material into floor joints through its rotation. The disc has a specific structure with channels and edges that enable it to self-feed and self-applied jointing material without requiring manual intervention from the operator, significantly increasing grouting speed.
Solution Approach 2:
The patent replaces the manual mechanical action of a hand trowel with an automated rotating grouting disc driven by the machine's motor. This substitution of manual operation with automated mechanical rotation dramatically reduces the time required for grouting while maintaining effective jointing material application.
3Extent of automation
If a grouting disc device is added to the grinding machine, then automatic grouting is enabled, but the device complexity increases
Solution Approach 1:
The grouting function is implemented as a separate, modular grouting disc that can be independently attached to and removed from the grinding machine. This segmentation allows the grouting component to be added without fundamentally redesigning the entire machine, reducing the increase in overall device complexity while still enabling automatic grouting.
Solution Approach 2:
The grouting disc is designed as a dynamic component that rotates with the grinding disc, utilizing the existing drive mechanism's rotation to perform grouting operations. This dynamic integration allows automatic grouting to be achieved without adding complex control systems, as the grouting action naturally follows the rotation cycle of the existing motor.

AI summary
The present invention relates to a disc device (5) for a grinding machine (1), in particular for a single-disc floor grinding machine, for incorporating a jointing material into parquet floors, wooden floors or the like, with a disc-shaped carrier plate (6) which has a pivot axis (7) and a floor-facing surface (10); and several sheet-strip-shaped wing elements (16), each of which has a fastening section (17) for attaching the several wing elements (16) to the floor-facing surface (10) of the carrier plate (6) and each has a spatula edge (20) which, during operation, rests at least partially on the floor to be processed;wherein the multiple wing elements (16) are arranged circumferentially around the axis of rotation (7) of the carrier plate (6) to form an internal jointing material area (23) such that the respective spatula edges (20) of the multiple wing elements (16), when the carrier plate (6) rotates during operation, exert a spatula movement to work the jointing material located within the jointing material area (23) into the floor to be treated and a force component on the jointing material located within the jointing material area (23) such that the spatula edges (20) of the multiple wing elements (16) convey the jointing material against the centrifugal force towards the inside of the carrier plate (6) to enclose the jointing material within the jointing material area (23). The present invention further relates to a grinding machine (1) with such a disc device (5).
