Sliding Cutting Machine Motor Layout for Clear Cut-Line Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding cutting machines often obstruct the user's visibility of the cutting location due to the placement of structural elements, requiring users to lower their head to confirm the cutting position.
Innovation Solution
The sliding cutting machine design positions the electric motor between the cutting tool and the slide bars, with the motor shaft parallel or tilted by 10° or less relative to the cutting tool, and the motor housing disposed on one side of the cutting tool, allowing no structural elements to protrude on the opposite side, enhancing visibility and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor housing is disposed protruding leftward (opposite side of slide bars), then the electric motor can be positioned away from the slide bars, but the motor housing obstructs visibility of the cutting location
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the motor housing on the same side as the slide bars rather than opposite them. This reversal eliminates the visibility obstruction problem while maintaining functional separation between components through careful spatial arrangement within the cutting-machine main body.
Solution Approach 2:
The patent resolves the visibility issue by utilizing the vertical dimension and internal spatial arrangement. The motor housing is positioned within the cutting-machine main body structure, using upward and lateral positioning rather than protruding forward, thereby eliminating obstruction in the user's line of sight while maintaining component functionality.
2Ease of operation
If the motor housing is disposed tilted upward (extending rightward away from cutting tool), then the electric motor can be positioned away from the cutting tool, but the slide bars obstruct visibility of the cutting location
Solution Approach 1:
The patent inverts the conventional tilted arrangement by positioning the motor housing to extend in a direction that does not create visibility obstructions. Instead of tilting upward away from the cutting tool, the motor housing is arranged to extend laterally or vertically within the main body, eliminating the visibility problem while maintaining motor positioning.
Solution Approach 2:
The patent employs asymmetric arrangement of the motor housing relative to the cutting tool and slide bars. By positioning the motor housing asymmetrically within the main body structure rather than using symmetric protrusions, the design achieves both visibility and functional requirements through optimized spatial configuration.
3Ease of operation
If structural elements protrude on one side of the cutting tool, then the electric motor can be positioned away from the slide bars, but users must lower their head to confirm cutting position
Solution Approach 1:
The patent extracts the motor housing from the protruding position and integrates it within the cutting-machine main body structure. This extraction eliminates the visibility obstruction and ergonomic issue while maintaining the motor's functional positioning through internal mounting arrangements.
Solution Approach 2:
The patent merges the motor housing with the cutting-machine main body structure, creating an integrated assembly where the motor housing does not protrude independently. This merging eliminates visibility obstructions and improves ergonomics while maintaining all functional requirements through unified structural design.
