Adjustable Handle Position Marking for Portable Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable working machines face difficulties in returning the handle to its original position and angle after changes during storage or transport.
Innovation Solution
A working machine with a handle that includes a fixing mechanism and markers to indicate position and angle, allowing for precise repositioning and angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle position is adjusted during storage or transport, then the handle can be repositioned for different operational needs, but the handle cannot be returned to the original position accurately
Solution Approach 1:
The patent applies preliminary action by providing reference marks on both the handle and the connecting portion before the handle is repositioned. These marks indicate the original position and angle, enabling the operator to return the handle to its initial state accurately after adjustment during storage or transport.
Solution Approach 2:
The patent uses visual markers (reference marks) on the handle and connecting portion to indicate position and angle. These marks provide visual feedback to the operator, enabling precise reproduction of the original handle configuration after repositioning.
2Stability of the object's composition
If the handle is fixed tightly to the connecting portion, then the handle position is stable during operation, but the handle cannot be adjusted or repositioned easily
Solution Approach 1:
The patent applies dynamics by designing the fixing mechanism to be adjustable rather than permanently fixed. The handle can be loosened for repositioning and tightened for stable operation, allowing the system to transition between adjustable and fixed states based on operational requirements.
Solution Approach 2:
The fixing mechanism serves multiple functions: it allows the handle to be adjusted during operation, enables repositioning during storage and transport, and provides stable fixation during use. The reference marks system simultaneously supports both adjustment and position reproduction functions.
