Solution Overview
Problem
Existing floor grinding pads exhibit uneven wear and inconsistent performance due to rigid designs that fail to maintain even contact with uneven floors, leading to prolonged grinding times and suboptimal results.
Innovation Solution
A flexible grinding pad apparatus featuring a spring steel reinforcement ring with diamond-based abrasive disks or dots, allowing for radial stiffness and torsional flexibility, ensuring all disks maintain contact with the floor even on uneven surfaces, and mechanical fasteners for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid grinding pad design is used, then structural stability is improved, but contact uniformity with uneven floors deteriorates
Solution Approach 1:
The grinding pad incorporates a flexible reinforcement layer that allows dynamic adaptation to floor irregularities. This layer can flex and deform to maintain contact between the abrasive disks and uneven floor surfaces, resolving the contradiction between structural stability and contact uniformity by introducing controlled flexibility rather than complete rigidity.
Solution Approach 2:
The patent uses a flexible reinforcement layer as a thin film structure that provides minimal structural support while allowing the abrasive disks to conform to uneven floor surfaces. This flexible film approach maintains enough stability for structural integrity while enabling the necessary deformation for uniform contact across irregular surfaces.
2Manufacturing precision
If a flexible grinding pad design is used, then contact uniformity with uneven floors is improved, but structural stability deteriorates
Solution Approach 1:
The grinding pad uses a composite structure combining a flexible base pad material with a reinforcement layer. This composite design provides the flexibility needed for uniform contact on uneven surfaces while the reinforcement layer contributes structural stability, preventing the pad from becoming too compliant and losing its load-bearing capability.
3Productivity
If multiple abrasive disks are used on a rigid pad, then grinding efficiency is improved, but wear uniformity deteriorates
Solution Approach 1:
The flexible reinforcement layer allows each abrasive disk to independently adapt to floor irregularities, ensuring that all disks maintain consistent contact pressure with the floor. This dynamic adjustment prevents uneven wear patterns that would occur with a rigid pad where some disks might be elevated or have reduced contact.
4Ease of manufacture
If a rigid pad structure is used, then ease of manufacture is improved, but adaptability to uneven floors deteriorates
Solution Approach 1:
The reinforcement layer is constructed as a flexible thin film that can be relatively easily manufactured and attached to the base pad. This flexible film structure provides adaptability to uneven floor surfaces without requiring complex manufacturing processes, maintaining ease of manufacture while significantly improving adaptability compared to fully rigid designs.
