Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing log splitters face issues with constant lubrication needs for guides due to friction, leading to wear and accumulation of dirt, especially in moist environments, and existing solutions do not effectively address this problem for vertical splitters.
Innovation Solution
The use of sliding plates made from a combination of base materials with 0.5 to 80% graphite or graphene, which improves sliding characteristics and eliminates the need for lubrication, by incorporating graphite or graphene into the plates during manufacture or as inserts or thin layers, or adding it to the base plate or guide surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sliding plates are used without special materials, then the structure is simple and manufacturing is easy, but the sliding plates experience increased wear due to friction and require constant lubrication
Solution Approach 1:
The sliding plates are made from a composite material consisting of base material (such as brass or plastic) combined with 0.5 to 80% graphite or graphene. This composite structure provides self-lubricating properties that reduce friction and wear during sliding operations, eliminating the need for constant lubrication while maintaining structural integrity and reducing device complexity
2Reliability
If constant lubrication is applied to the guides, then wear of sliding plates is reduced, but dirt accumulates on the guide and lubrication system becomes contaminated
Solution Approach 1:
The sliding plates incorporate self-lubricating graphite or graphene materials directly into their structure (0.5 to 80% by weight). This self-service mechanism provides continuous lubrication during sliding operations without requiring external lubrication systems, thereby preventing dirt accumulation on guides and eliminating contamination issues associated with conventional lubrication
3Ease of operation
If graphite or graphene is added to base material during manufacture, then sliding characteristics are improved and lubrication is eliminated, but manufacturing process becomes more complex
Solution Approach 1:
The invention specifies a quantitative range for graphite or graphene content (0.5 to 80% by weight) that can be added to the base material during manufacturing. This parameter change approach allows manufacturers to optimize the balance between sliding characteristics and manufacturing complexity by selecting appropriate concentrations within the specified range, with thinner layers (0.5-10%) requiring less complex processing while still providing effective self-lubrication

AI summary
The present invention belongs to the field of forestry and wood processing, more precisely to the field of devices for splitting logs having special sliding plates for guides, along which the base plate of the axe slides. The present invention relates to improved sliding plates for a log splitter and a log splitter with said sliding plates. The essence of the invention is in that the sliding plates are made of a combination of base material and from 0.5 to 80 % (w/w) of graphite or graphene, which improves the sliding characteristics of the plates. The base material may be brass, different plastic materials or any other suitable material. Sliding plates may be produced by adding graphite to the base material during manufacturing of the plates or graphite is included in the form of graphite inserts or layers to the already made plates. Alternatively, the graphite may be added to the base plate of the axe or the guides of the log splitter. Thus, the invention eliminates the need for lubrication of guides in a log splitter.
