Compound Container with Expandable Hand Support and Side Stands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drywall compound containers lack ergonomic design and stability, making them difficult to hold and use, especially when combined with a taping knife, and they are not stackable for efficient storage.
Innovation Solution
A hand-held compound container with an adjustable expandable hand support member and side stands for enhanced grip and stability, along with a tool holder for securing a taping knife, and a design that allows for stacking without compromising usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional compound container without hand support is used, then the container structure is simple, but the user's hand cannot be securely held and the container is difficult to control
Solution Approach 1:
The hand support member is designed as an expandable dynamic structure that transitions from a compressed state during transport to an expanded state during use. This dynamic transformation allows the container to adapt between two functional requirements: portability and ergonomic handling comfort.
Solution Approach 2:
The hand support member is nested within the container body when not in use, occupying minimal space. When deployed, it extends outward to provide the necessary hand support surface, effectively nesting a functional component within the container's existing structure.
2Stability of the object's composition
If the container has a flat bottom for stability, then the container is stable on surfaces, but the container cannot be stacked efficiently for storage
Solution Approach 1:
The support function is segmented between two distinct elements: the flat bottom provides stability when the container is in use, while separate side stands provide support when stacked. This segmentation allows each element to optimize for its specific function without compromising the other.
Solution Approach 2:
The side stands extend vertically from the container sides, utilizing the vertical dimension to provide support points that enable stacking. This dimensional addition allows the container to achieve both stability on flat surfaces and stackability without modifying the flat bottom design.
3Ease of operation
If the container has a rounded bottom for easy gripping, then the user's hand can be easily gripped, but the container cannot stand stably on flat surfaces
Solution Approach 1:
The support and gripping functions are divided between different geometric features: rounded corners on the bottom provide ergonomic gripping, while the flat bottom surface and side stands provide stability. This functional segmentation resolves the contradiction between ease of gripping and stability.
4Ease of operation
If the container includes integrated tool holder, then tool storage is convenient, but the container structure becomes more complex
Solution Approach 1:
The tool holder is merged with the side stand structure, combining two functions (tool storage and structural support) into a single integrated element. This merging reduces overall complexity compared to adding a separate tool holder component while maintaining both functionalities.
Solution Approach 2:
The side stand serves multiple functions: providing structural support for stacking, enabling the container to stand upright, and serving as an integrated tool holder. This multi-functionality reduces the need for additional components while enhancing operational convenience.
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 container provides improved user comfort and stability during use, secure storage for tools, and efficient stacking, enhancing usability and storage efficiency in drywall construction.
Implementation Method 1
the hand support member can be stretched to an expanded configuration, applying an elastic force on the user's hand and thereby enhancing a holding of the compound container by the user's hand
Implementation Method 2
a tool holder including a friction holding tab for holding a taping knife

AI summary
A compound container includes a container body having a side wall and a bottom wall; an interior space defined by the side wall and the end wall; an opening defined by an upper edge of the side wall; and an elongated hand support member having a first attachment section and a second attachment section for attaching the hand support member to a bottom surface of the bottom wall. The hand support member is positioned generally parallel to the opening defined by the upper edge of the side wall.
