Cutting Tool Impact Protecting Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorized gardening devices, such as hedge trimmers, are prone to damage from impacts and are difficult to store stably due to their length, which can lead to instability and increased wear on electronic components.
Innovation Solution
A cutting tool design featuring a housing with a rigid impact protecting member, comprising a substantially straight and transverse rigid portion fixed via arms at an acute angle, providing protection from impacts and serving as a stable platform for vertical storage, thereby reducing wear and enhancing environmental resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid impact protecting member is added to the housing, then protection from impacts is improved, but device complexity increases
Solution Approach 1:
The impact protecting member is integrated within the housing structure, with arms extending from the housing to support the rigid portion. This nested configuration provides impact protection while utilizing the existing housing space, minimizing additional complexity.
Solution Approach 2:
The rigid portion of the impact protecting member serves dual functions: it acts as a shield to absorb and distribute impact forces away from the housing, and simultaneously provides a stable platform for vertical storage of the cutting tool. This multi-functionality reduces the need for separate components.
2Length of moving object
If the cutting tool is made longer to extend from the housing to the cutting element, then cutting reach is improved, but stability during storage deteriorates
Solution Approach 1:
The solution addresses the storage stability issue by introducing a transverse dimension through the rigid portion of the impact protecting member. This horizontal extension provides a broad base for vertical storage, stabilizing the long tool without requiring changes to the longitudinal extension necessary for cutting reach.
3Adaptability or versatility
If electronic components are added to the housing to improve functionality, then device capability is improved, but vulnerability to impact damage increases
Solution Approach 1:
The rigid impact protecting member acts as an intermediary barrier between external impact forces and the housing containing electronic components. It intercepts and dissipates impact energy through its arms and rigid portion, protecting the vulnerable electronics while allowing the housing to maintain its full electronic functionality.

AI summary
A cutting tool including a housing, the cutting tool having a longitudinal extension from the housing to a cutting element provided at the distal end of the cutting tool. The housing is provided with a rigid impact protecting member having at least a rigid portion, the rigid portion being transverse to the longitudinal extension of the cutting tool and provided at a distance from the housing such that the housing is protected from an impact.
