Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing horizontal sectioning machines face safety hazards due to fixed obstacles like goniometric squares and pushers, and they lack flexibility and precision in making angled cuts, failing to meet current safety regulations and increasing mechanical complexity and costs.
Innovation Solution
A sectioning machine with an angular cutting group featuring a hinged guiding rod adjustable via a trapezoidal screw and optical detector for precise panel positioning, eliminating fixed obstacles and enhancing safety and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed goniometric squares are used for angled cuts, then cutting precision is improved, but operator safety deteriorates due to obstacles in the cutting area
Solution Approach 1:
The patent removes the fixed goniometric square from the cutting area and extracts only the essential function of angle definition. The angle is now defined by the relationship between the movable cart and the worktable, eliminating the physical obstacle while preserving the precision function through the guiding rod and clamp mechanism.
Solution Approach 2:
The patent introduces a guiding rod as an intermediary element that transfers the angle definition function from the removed fixed square to the movable cart system. The guiding rod works with the clamp to define the cutting angle without creating safety hazards in the cutting path.
2Ease of operation
If traditional pushers are used for panel positioning, then panel movement is facilitated, but operator safety deteriorates due to injury risks
Solution Approach 1:
The patent removes the traditional pusher from the cutting area, extracting only the essential function of panel advancement. This function is now performed by the movable cart with clamps that grip and advance the panel from a safe position, eliminating the safety hazard while maintaining operational ease.
3Adaptability or versatility
If retractable carts with aligners are used for panel positioning, then positioning flexibility is improved, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent makes the movable cart universal by giving it multiple functions: it positions the panel, defines the cutting angle through the guiding rod, and provides clamping. This consolidation of functions into a single device reduces overall system complexity while maintaining positioning flexibility and adaptability.
