Working Machine Adjusting Member for Posture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines face difficulties in adjusting the attaching posture of the working member due to processing challenges on the output shaft and experience fastener loosening when load is applied, particularly in swinging applications.
Innovation Solution
A working machine configuration that includes a prime mover, an output shaft, a first adjusting member detachably attached to the output shaft, and a working member with an attaching part on the output shaft and an adjusting part on the working member, allowing for easy adjustment of the attaching posture and preventing fastener loosening by interposing the working member between the fastener and the output shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjusting part is disposed on the output shaft, then the attaching posture can be adjusted, but processing of the adjusting part on the output shaft becomes difficult
Solution Approach 1:
The adjusting mechanism is divided into two separate components: an adjusting part attached to the output shaft and an adjusting member attached to the working member. This segmentation allows each part to be processed and manufactured independently, simplifying the processing difficulty while maintaining the posture adjustment functionality.
Solution Approach 2:
The adjusting member acts as an intermediary component between the output shaft and the working member. It transmits the adjustment function from the adjusting part on the output shaft to the working member, enabling posture adjustment without requiring complex processing on the output shaft itself.
2Productivity
If the working member is pressed against the ground while swinging, then the working member can perform its function, but load causes the working member to swing relative to the swing member, loosening the fastener
Solution Approach 1:
The adjusting member serves as an intermediary between the fastener and the working member. It absorbs and distributes the load generated when the working member contacts the ground, preventing direct transmission of swing-induced forces to the fastener and thereby preventing fastener loosening.
Solution Approach 2:
The adjusting member is designed to provide cushioning or compliance in advance against the loads that occur during ground contact. This pre-planned compliance mechanism prevents the working member from swinging relative to the swing member under load, thereby maintaining fastener tightness.

AI summary
A working machine may include: a prime mover; an output shaft configured to move by movement of the prime mover; a first adjusting member detachably attached to the output shaft; and a working member detachably attached to the first adjusting member. The first adjusting member may include: an attaching part attached to the output shaft; and an adjusting part attached to the working member and configured to adjust an attaching posture of the working member relative to the first adjusting member.
