Innovation Solution

A modular device with a variable configuration, including a machine base, storage module, processing unit, and workpiece receiving device, allowing the storage module to pivot relative to the machine base or be fixed, and the workpiece receiving device to pivot relative to the storage module, enabling flexible attachment and processing of saw blades of varying sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple machine concepts and parts are used for different saw blade diameters, then the device can handle various workpiece sizes, but the production becomes complex and expensive

Engineering Contradiction:
Improveability to process different saw blade diametersVSAvoidnumber of machine concepts and parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal machine base that can accommodate different saw blade diameters through a standardized mounting interface. The machine base includes a universal chuck mechanism that can be adjusted to hold various workpiece sizes, eliminating the need for multiple specialized machine concepts. This multi-functional design allows a single machine structure to perform sharpening operations on different saw blade diameters, directly reducing production complexity while maintaining versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device is divided into modular components including a universal machine base, interchangeable mounting adapters, and adjustable sharpening mechanisms. Each module can be independently configured for different workpiece sizes, allowing the system to handle various saw blade diameters without requiring complete machine redesign. This segmentation enables flexible reconfiguration while maintaining a core standardized platform

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If specialized machine structures are designed for specific applications, then the sharpening precision is optimized, but the production cost increases

Engineering Contradiction:
Improvesharpening precisionVSAvoidproduction complexity and cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent employs adjustable parameters within the universal machine structure, including variable chuck jaw positions, adjustable sharpening wheel distances, and configurable feed rates. These parameters can be modified to optimize sharpening precision for different saw blade diameters and types without requiring specialized machine structures. The standardized platform maintains precision through parameter adjustment rather than structural specialization, reducing manufacturing complexity and cost
