Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manually-operating grinding machines or automatic grinding machines with fixed jigs are used, then ice blade shaping can be accomplished, but precision and consistency are poor

Engineering Contradiction:
Improveice blade shaping precisionVSAvoidgrinding system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical fixed jigs and templates with a computer vision system using cameras and image processing algorithms. The system captures images of the ice blade, processes them to determine the blade shape, and compares it against desired shape parameters. This substitution of mechanical measurement systems with optical and computational systems enables precise, customizable shaping without the limitations of fixed physical guides.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If fixed jigs and templates are used for sharpening, then a standard shape can be applied, but user customization is limited

Engineering Contradiction:
Improveice blade shape customizationVSAvoidsharpening system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic system where the desired ice blade shape is not fixed but can be customized by users through input parameters. The system allows users to specify various shape characteristics and adjusts the grinding process accordingly. This dynamic adaptability is achieved through software control that processes user inputs and generates appropriate grinding paths, enabling versatile customization without requiring multiple physical templates.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables customization by allowing users to modify various parameters that define the ice blade shape. These parameters can include curvature, edge angles, and other geometric properties. The computer vision system and control software process these parameter changes and translate them into specific grinding operations, providing flexible adaptation to different user preferences and performance requirements.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If trial and error methods are used for ice blade shaping, then some customization is possible, but time consumption and inconsistency increase

Engineering Contradiction:
Improvesharpening efficiencyVSAvoidshape consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements a feedback mechanism where the camera system continuously monitors the ice blade shape during the sharpening process. The captured images are processed to determine the current blade geometry, which is then compared against the desired shape parameters. This feedback loop allows the system to make real-time adjustments to the grinding process, ensuring that the final product matches the specified requirements consistently, eliminating the trial-and-error approach.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of the ice blade's current shape using image processing before the actual sharpening begins. This preliminary action includes capturing images, processing them to determine existing geometry, and comparing it with the desired shape. By preparing this information in advance, the system can plan the grinding operations more efficiently and achieve consistent results without repeated adjustments.

Inventive Principle:
Principle #10Preliminary action
