Rotating Lockable Handle for Ergonomic Container Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers, particularly waste containers, are ergonomically challenging to handle due to their weight and height, making them difficult to move and store efficiently, especially when filled, and often require non-ergonomic working postures for users.
Innovation Solution
A container design featuring a movable and lockable holding device that can be adjusted to increase the lever length, allowing for easier handling and storage, with a mechanism that allows the handle to be moved from a first position to a second position, providing a longer lever arm for improved ergonomics and ease of use, while maintaining a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the handle area is fixed at a low height to enable space-saving storage under worktops, then the container can be stored compactly, but the handling becomes non-ergonomic and difficult for normal-sized persons
Solution Approach 1:
The holding device is designed to be movable between a retracted first position for compact storage and an extended second position for ergonomic handling. The device can be rotated about an axis of rotation and locked in the second position, transforming the handle height dynamically based on operational needs rather than being fixed at a low height.
2Ease of operation
If the container is designed with a long lever arm for easier handling, then the ergonomics improve, but the overall height and structure become more complex
Solution Approach 1:
The holding device utilizes a rotatable mechanism with connecting arms that can be locked in position. This dynamic structure allows the long lever arm to be deployed only when needed for handling, while remaining compact during storage, thus avoiding permanent structural complexity.
Solution Approach 2:
The holding device is divided into multiple segments including connecting arms, a holding element, and a locking mechanism. This segmentation allows each component to perform its specific function while contributing to the overall compactness when retracted and functionality when extended.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable handle device enhances the ergonomic handling of the container by allowing it to be gripped at an advantageous height, reducing the effort required to move it, and facilitates space-saving storage, improving user safety and convenience.
Implementation Method 1
the holding device has a handle area, which can be moved from a first position, in which the handle area is arranged between the lower level and the upper level, to a second position... so that a lever length determined by a distance between the lower level and the handle area is greater in the second position of the holding device than in the first position
