Cutting Work Machine Guard Member Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting work machines struggle to trim branches near structures due to the limitations imposed by guard members, which restrict the cutting area and require manual trimming, complicating the process of hedge and plant maintenance.
Innovation Solution
A cutting work machine design featuring a cutter unit with upper and lower blades that reciprocate in opposite directions, equipped with a guard member that includes a guard plate and a fixed blade projecting in different directions, allowing for protection of the blade edges and enabling cutting of branches between the fixed blade and the cutting edges, thereby expanding the cuttable area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a guard member is provided at the front end portion of the cutter support to prevent the blade from hitting a structure, then the blade is protected from damage, but the cutting area is narrowed and branches near structures cannot be trimmed
Solution Approach 1:
The guard member is divided into a guard plate and a fixed blade, where the guard plate protects the blade from hitting structures while the fixed blade extends in the opposite direction to enable cutting of branches near structures. This segmentation allows the guard member to perform both protection and cutting functions simultaneously.
Solution Approach 2:
The guard member is designed to serve multiple functions: the guard plate protects the blade from damage when approaching structures, while the fixed blade enables the cutting of branches near structures. This multi-functionality resolves the contradiction between protection and cutting capability.
2Reliability
If a saw is placed between the guard member and the foremost cutter edge of the blade to protect the blade, then the blade is protected from hitting structures, but the area that can be cut by the blade is narrowed
Solution Approach 1:
The protective element is segmented into a guard plate and a fixed blade, where the guard plate provides protection and the fixed blade maintains cutting capability. This segmentation eliminates the need for a separate saw and preserves the blade's cutting area.
Solution Approach 2:
The guard member is designed to perform both protection and cutting functions through its dual components, eliminating the need for additional cutting elements like saws and maintaining full cutting efficiency while protecting the blade.
3Ease of operation
If the guard member is positioned to protect the blade, then manual trimming of branches near structures is avoided, but the configuration becomes more complex
Solution Approach 1:
The guard plate and fixed blade are merged into a single guard member assembly that is fixed to the cutter support. This merging integrates protection and cutting functions into one component, simplifying the overall configuration while enabling easy operation of branches near structures.

AI summary
The present invention provides a cutting work machine, wherein a cutter unit includes upper and lower blades, which are connected to an upper cutter support, and a guard member that is provided on the upper cutter support. Both blades reciprocate in opposite front-back directions. The guard member includes a guard plate that projects to the right from the upper cutter support and a fixed blade that projects to the left from the upper cutter support. Front edge portions of the guard plate and the fixed blade are positioned forward of foremost cutting edges of both blades. The fixed blade faces forward against the foremost cutting edge of the upper blade.
