Work Machine Pole Guide Groove Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in connecting the first and second partial poles of work machines due to the need to align and engage positioning members and rotation shafts, which can be challenging with heavy objects and requires repeated adjustments.
Innovation Solution
Incorporating a guide groove with an escapable section in the joint member to facilitate the alignment of rotation shafts and allow the positioning member to escape, enabling easy insertion and connection of the first partial pole without removing it from the joint member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning member and positioning hole are provided to connect the first and second partial poles, then the connection position and direction are accurately determined, but the user faces difficulties in engaging the positioning member with the positioning hole due to the heavy weight of the tool unit and power unit
Solution Approach 1:
A guide groove is introduced as an intermediary element between the positioning member and positioning hole. The guide groove extends from the through hole toward one side and guides the positioning member to the positioning hole, making the engagement process easier while maintaining accurate positioning. The guide groove acts as a mediator that facilitates the connection without compromising the precision provided by the positioning member and hole.
2Power
If the first partial pole is made heavy with the tool unit to provide sufficient cutting power, then the cutting performance is improved, but the operation of sliding or rotating the first partial pole relative to the joint member becomes difficult
Solution Approach 1:
The guide groove serves as a mediator that reduces the operational difficulty caused by the heavy weight of the tool unit. By providing a guided path for the positioning member, the guide groove eliminates the need for difficult sliding or rotating operations, allowing the heavy first partial pole to be easily connected to the joint member while maintaining full cutting power.
3Adaptability or versatility
If the main pole is divided into multiple partial poles for easy storage and transport, then the portability is improved, but the connection process becomes complex requiring precise alignment of positioning members
Solution Approach 1:
The guide groove acts as an intermediary that simplifies the connection process of the divided main pole. By guiding the positioning member to the positioning hole, the guide groove eliminates the complexity of precise alignment that would otherwise be required when connecting multiple partial poles. This maintains the portability benefit while reducing assembly complexity.

AI summary
A work machine includes a main pole internally including a rotation shaft, a tool unit located at one end of the main pole, and a power unit located at another end of the main pole. The main pole includes a first partial pole, a second partial pole and a joint member that joints them to each other. The first partial pole includes a positioning member. The joint member includes a positioning hole configured to engage with the positioning member and a guide groove extending from the positioning hole. The guide groove is configured to guide the positioning member to the positioning hole and to allow the positioning member to escape in at least a section thereof.
