Repositionable Corner Handle Assembly for Industrial Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial machines lack a versatile and efficient handle system that allows for easy lifting and movement, with existing handles often being non-adjustable and not accommodating users of varying heights.
Innovation Solution
An industrial machine assembly featuring a handle with a grasping portion and flanges that can be releasably attached in two positions, allowing the flanges to straddle corners formed by the machine's side and upper walls, facilitating secure attachment and adjustable positioning for different user heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed handle position is used on industrial machines, then the structure is simple, but it does not accommodate users of varying heights
Solution Approach 1:
The handle attachment system transitions from a fixed position to a dynamic, adjustable configuration. The handle can be detached and reattached at different positions (first and second positions) on the machine frame, allowing users to adjust the handle height according to their needs. This dynamic adjustability resolves the contradiction by enabling position adaptation without requiring a completely complex system.
Solution Approach 2:
The handle attachment system is segmented into discrete attachment points on the machine frame and a detachable handle component. The frame includes multiple openings at different heights, and the handle can be selectively attached to different openings, creating modular adjustability. This segmentation allows for simplified adaptation compared to a fully continuous adjustment mechanism.
2Ease of operation
If handles are made detachable and adjustable, then user comfort is improved, but the attachment mechanism becomes more complex
Solution Approach 1:
The handle attachment mechanism enables easy detachment and reattachment of the handle at different positions. Users can simply remove the handle from one opening and attach it to another opening on the frame. This dynamic attachment system improves ease of operation while maintaining relatively simple mechanism complexity through straightforward mechanical interfaces.
Solution Approach 2:
The same handle component can be attached to multiple different openings on the frame, serving multiple positions and functions. The universal attachment design allows one handle to work with various attachment points, simplifying the overall system while providing operational flexibility for different user heights and preferences.
3Adaptability or versatility
If multiple handle positions are provided, then versatility for different users is achieved, but manufacturing complexity increases
Solution Approach 1:
The frame is designed with discrete, segmented openings at specific heights rather than a continuous adjustment mechanism. These openings are positioned at predetermined locations that accommodate different user heights. The segmented approach simplifies manufacturing compared to creating a fully continuous adjustment system, as the openings can be easily formed during frame fabrication.
Solution Approach 2:
The frame structure incorporates local openings at specific positions where handle attachment is needed, rather than modifying the entire frame structure. This local quality approach allows the majority of the frame to maintain its original simple structure, while only specific localized areas are modified to include attachment openings, minimizing manufacturing complexity.

AI summary
An industrial machine assembly includes an industrial machine and a handle. The industrial machine includes an upper wall and a side wall. The side wall and upper wall cooperate to define a corner. The handle includes a grasping portion, a first flange, and a second flange. The handle is configured for attachment to the industrial machine in one of a first position and a second position. When the handle is in the first position, the first and second flanges straddle the corner such that the first flange is adjacent to the upper wall and the second flange is adjacent to the side wall. When the handle is in the second position, the first and second flanges straddle the corner such that the first flange is adjacent to the side wall and the second flange is adjacent to the upper wall.
