Chainsaw Case Segmentation for Oil Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chainsaws release lubricating oil during storage and transport, leading to environmental pollution and fouling, and existing cases do not effectively collect or dispose of this oil, nor ensure stable and safe application during these processes.
Innovation Solution
A case with a housing volume for the blade and a separate collection volume for oil, designed to facilitate oil collection and disposal, featuring a liquid conveyor system and locking mechanisms for secure attachment to the blade, allowing for easy oil transfer and containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chainsaw is stored in a vertical orientation with the blade at the bottom, then the blade is easily accessible and can be engaged to a support hook, but the lubricating oil released by the blade accumulates inside the case causing fouling and pollution
Solution Approach 1:
The case is divided into two separate chambers: a housing volume for containing the blade and a collection volume for collecting lubricating oil. This segmentation allows the oil to be directed away from the blade housing and collected in a dedicated area, preventing fouling while maintaining easy storage orientation.
Solution Approach 2:
A liquid conveyor system acts as an intermediary between the housing volume and collection volume, directing the lubricating oil from the blade area to the collection area. This intermediary mechanism ensures oil is channeled away from the blade housing, preventing pollution while maintaining the convenient vertical storage orientation.
2Device complexity
If a traditional case is used without a collection volume, then the case structure is simple, but the lubricating oil released by the blade causes fouling of the inside of the case and environmental pollution
Solution Approach 1:
The case is segmented into a housing volume for the blade and a collection volume for oil, with the collection volume being a distinct separated space. This segmentation adds minimal structural complexity while effectively preventing oil fouling by directing oil to a dedicated collection area rather than allowing it to spread throughout the entire case.
Solution Approach 2:
A liquid conveyor serves as an intermediary component that bridges the housing volume and collection volume, efficiently directing oil with minimal additional structure. This intermediary mechanism prevents fouling while maintaining relatively simple case construction.
3Ease of operation
If the case is designed without secure locking means, then the case is easy to apply and remove, but the case can be incorrectly applied and separate from the blade during vertical storage
Solution Approach 1:
The locking means are designed to automatically engage when the case is correctly positioned on the blade, providing self-securing functionality. This self-service mechanism ensures reliable attachment during vertical storage without requiring complex manual locking operations, maintaining ease of application while ensuring stability.

AI summary
The invention relates to a case (9) configured to be applied, for the purposes of containment and/or protection, to a blade (8) of a chainsaw (7). The case (9) delimits a housing volume (28) of the blade (8) therein, the housing volume (28) extending along a longitudinal axis (V) coinciding with the main extension direction of the blade (8) when the blade (8) is arranged in the housing volume (28). According to the invention, the case (9) further delimits a collection volume (29) of lubricating and/or protective oil therein, possibly released by the blade (8) during a storage or transport step of the chainsaw (7), the collection volume (29) being in communication with the housing volume (28). The invention further relates to a method for the disposal of lubricating and/or protective oil, possibly released by a blade (8) of a chainsaw (7) during a storage or transport step of the chainsaw (7).
