Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chip discharging devices accumulate chips in corners, leading to increased cleaning time due to angular corners in the design of the enclosing member and gutter.
Innovation Solution
A chip discharging device with a chip shooter featuring a guide wall surface composed of vertical and inclined wall surfaces connected by flat or curved surfaces, preventing chip accumulation in corners and facilitating easy mounting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the enclosing member and gutter are formed with angular corners to simplify manufacturing, then manufacturing cost is reduced, but chips accumulate in the corners requiring more cleaning time
Solution Approach 1:
The patent applies curvature by forming the gutter with a U-shaped cross-section that has rounded corners instead of sharp angular corners. This curved geometry prevents chips from accumulating in corner areas, allowing chips to be efficiently conveyed without requiring additional cleaning time, thus resolving the contradiction between manufacturing simplicity and cleaning time requirement.
2Productivity
If the chip shooter is designed with asymmetric features to optimize chip flow in one direction, then chip discharge efficiency is improved, but the device cannot be mounted on both sides of the machine requiring separate designs
Solution Approach 1:
The patent employs asymmetric design in the chip shooter components, specifically making the left and right chip shooters mirror images of each other. This asymmetric yet symmetrical approach allows each chip shooter to be optimized for its specific mounting position while maintaining the capability to be installed on either side of the machine, thus achieving both chip discharge efficiency and mounting flexibility.
Solution Approach 2:
The patent achieves universality by designing the chip shooter as a standardized component that can be mounted on either the left or right side of the machine tool. The symmetric mirror-image design of left and right chip shooters allows a single design family to serve multiple mounting positions, eliminating the need for completely separate designs and reducing overall system complexity.
3Productivity
If separate chip shooter designs are created for left and right sides to optimize performance, then chip discharge performance is improved, but molding costs increase
Solution Approach 1:
The patent uses asymmetric mirror-image design where the left and right chip shooters are essentially the same component reflected across a vertical axis. This approach allows for optimized chip discharge performance on both sides while requiring only one unique mold design, significantly reducing molding costs compared to creating completely separate asymmetric designs for each side.

AI summary
A chip discharging device of a machine tool is equipped with a chip discharging member for discharging chips generated by machine processing to a workpiece to an outside of the machine tool, and a chip shooter for introducing the chips to the chip discharging member. The chip shooter connects an introducing opening for introducing the generated chips and a discharging opening for discharging the chips toward the chip discharging member by a guide wall surface. The guide wall surface includes a vertical wall surface and a plurality of inclined wall surfaces inclined with respect to the vertical wall surface. At least a boundary parts between the inclined wall surfaces and a boundary part between the inclined wall surface and the vertical wall surface are formed by a flat surface or a curved surface.
