Adjustable Handle Carriage for Manual Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manually operable working implements, such as brooms and shovels, often require users to bend, twist, or strain due to fixed handle positions, which can lead to inefficiency, discomfort, or injury, especially as they do not account for individual user height, strength, or agility.
Innovation Solution
A manually operable carriage with interchangeable attachments, featuring a frame with adjustable receivers and handles, allowing users to customize the angle and position of the handle to accommodate different body types and tasks, enabling efficient use of various working implements like plows, logging clamps, and other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed handle position is used in manually operable implements, then the structure is simple and easy to manufacture, but the user experiences physical strain and discomfort due to inability to adjust for different body types
Solution Approach 1:
The handle is made adjustable rather than fixed, allowing it to change position dynamically to suit different users. The receiver mechanism enables the handle angle and position to be modified while maintaining structural integrity, resolving the contradiction between ease of operation and structural simplicity.
Solution Approach 2:
The handle parameters (angle, position, height) are made changeable through the receiver mechanism. Users can adjust these parameters to match their body dimensions, improving ease of operation without requiring complete redesign of the basic structure.
2Adaptability or versatility
If a one-size-fits-all dimension is used for implements, then manufacturing is simplified, but the implement does not accommodate different user heights, weights, or strengths
Solution Approach 1:
The receiver mechanism serves multiple functions: it accommodates different handle positions, angles, and lengths while using a single standardized component. This universal mechanism allows one implement design to serve users of various body types without requiring multiple specialized versions.
Solution Approach 2:
The implement is divided into modular components (handle, receiver, working portion) that can be independently adjusted or replaced. The receiver acts as a standardized interface that segments the adjustment function from the rest of the structure, simplifying manufacturing while enabling adaptability.
3Ease of operation
If the handle requires adjustment for different users, then comfort and efficiency improve, but the device becomes more complex with additional adjustment mechanisms
Solution Approach 1:
The receiver mechanism is designed to be easily operated by the user without requiring tools or complex procedures. Users can independently adjust the handle to their preferred position, making the adjustment system simple enough to be self-servicing while still providing comfort benefits.
