Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding machines are cumbersome to mount and dismount the water trough, leading to water spills and potential grindstone deterioration due to excessive soaking.
Innovation Solution
A grinding machine with a trough holder that can be easily lowered and raised using an intermeshing gear and toothed rack mechanism, allowing for simple mounting and dismounting, and adjustable height for different grindstone diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water trough is mounted by pushing it in position and lifting it up to hook on to a holder, then the trough can be secured to the grinding machine, but the mounting procedure becomes cumbersome and may result in water spill
Solution Approach 1:
The trough holder is made movable along a vertical guide slot, allowing it to be positioned at different heights. This dynamic positioning capability enables the holder to accommodate various grindstone diameters and simplifies the mounting process by allowing the trough to be easily lowered to a convenient mounting position and then raised to the operating position without manual lifting and hooking
Solution Approach 2:
A vertical guide slot is introduced as an intermediary structure between the housing and the trough holder. This guide slot provides a constrained path for the holder's movement, ensuring stable and secure vertical motion while preventing lateral displacement that could cause water spill during mounting operations
2Ease of operation
If the grindstone is left in contact with the liquid in the water trough at the end of the work day, then the trough remains in position, but excessive soaking of the grindstone and deterioration thereof occurs
Solution Approach 1:
The movable trough holder allows easy adjustment between mounted and dismounted positions. At the end of the work day, the holder can be lowered back to the mounting position, automatically separating the grindstone from the grinding liquid and preventing deterioration, while maintaining operational readiness for the next use
Solution Approach 2:
The system is designed to prevent the harmful effect of excessive soaking by providing a simple mechanism to separate the grindstone from the liquid. The preliminary action of lowering the holder prevents contact between the grindstone and grinding liquid, countering the potential deterioration before it can occur
3Device complexity
If the trough holder is fixed at a single height, then the structure is simple, but grindstones of different diameters cannot be properly wetted
Solution Approach 1:
The trough holder is designed with vertical movability along a guide slot, transforming it from a fixed structure to a dynamic one. This allows the holder to be positioned at different heights to accommodate grindstones of various diameters, ensuring proper wetting while maintaining a relatively simple overall structure through the use of a straightforward guide mechanism
Solution Approach 2:
The movable holder structure serves multiple functions: it provides stable mounting for the trough, enables adjustment for different grindstone sizes, and ensures proper positioning for effective wetting. This multi-functionality is achieved through the simple addition of vertical movement capability along the guide slot
