Floor grinding machine, handle for floor grinding machine and method of setting a handle for a floor grinding machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor grinding machines lack ergonomics and are cumbersome for storage and transportation due to their large size, failing to accommodate users with varying body conditions and requiring an improved design for efficient handling and compactness.
Innovation Solution
The floor grinding machine features a pivotable handle with locking devices that allow for easy transition between working and transport positions, incorporating a guide member and pivot angle limiting device to enhance ergonomics and compactness, along with a handle design that includes cross and longitudinal members for improved user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the floor grinding machine is designed with a fixed handle frame, then the structural stability is improved, but the ergonomics for users with different body conditions deteriorates
Solution Approach 1:
The handle frame is made pivotable relative to the machine frame, allowing it to move between a first position during operation and a second position during transport. This dynamic configuration enables the machine to adapt to different user needs while maintaining structural stability when locked in position.
2Adaptability or versatility
If the handle frame is made pivotable to improve ergonomics, then the adaptability to different users is improved, but the device complexity increases
Solution Approach 1:
The pivotable handle frame with locking mechanism provides adaptability for different users while maintaining relatively simple construction. The guide member ensures controlled movement along a predetermined path, and the locking device secures the handle in desired positions without requiring complex control systems.
Solution Approach 2:
A guide member is introduced as an intermediary element between the handle frame and the machine frame. This guide member constrains the pivot movement to a predetermined path, simplifying the overall mechanism by providing inherent guidance rather than requiring complex positioning systems.
3Productivity
If the machine is designed for operation with extended handle, then the operational effectiveness is improved, but the compactness for storage and transport deteriorates
Solution Approach 1:
The handle frame can be pivoted to a second position during transport that reduces the overall footprint of the machine. This dynamic reconfiguration allows the machine to maintain an extended handle position for effective operation while achieving a compact form factor for storage and transport.
