Washer Packaging with Retainer Beads for Column Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for washers does not allow for the simultaneous withdrawal of all washers in a single stacked column configuration, lacking features to retain washers in a column and within the packaging.
Innovation Solution
A semi-closed box washer carrier with retainer beads on the lateral walls and partial end walls, allowing a rod to be inserted to withdraw a column of washers by flexing the lateral walls apart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional packaging with lids or closures is used to retain washers, then the washers can be retained within the packaging, but the washers cannot be withdrawn in a single stacked column configuration
Solution Approach 1:
The packaging structure is segmented into a tray with multiple recessed spaces, each capable of holding a column of washers. The tray is divided into compartments that organize washers in vertical columns, allowing systematic withdrawal while maintaining structural integrity.
Solution Approach 2:
A rod is introduced as an intermediary tool to interact with the retainer bead and lateral walls. The rod applies force to flex the lateral walls apart, enabling the withdrawal mechanism without requiring direct manipulation of the packaging structure itself.
2Device complexity
If washers are allowed to move freely within the container, then the packaging is simple, but the washers cannot be organized in a stacked column configuration
Solution Approach 1:
The tray provides different local qualities within its structure: recessed spaces for holding washers, retainer beads for securing columns, and lateral walls for containment. Each region has a specific function that contributes to the overall stability of the washer arrangement.
Solution Approach 2:
The packaging structure is pre-configured with recessed spaces and retainer beads positioned to automatically organize washers into vertical columns as they are placed in the tray, eliminating the need for manual arrangement.
3Productivity
If retainer beads and lateral walls are added to retain washers in columns, then washers can be withdrawn in a single operation, but the packaging structure becomes more complex
Solution Approach 1:
The lateral walls are designed to be flexible rather than rigid, allowing them to bend outward when force is applied by the rod. This dynamic behavior enables the withdrawal mechanism to function with a simple rod insertion without requiring complex locking or release mechanisms.
Solution Approach 2:
The retainer bead and flexible lateral walls work together in a self-contained mechanism where the rod's insertion automatically triggers the wall flexing and washer release without requiring additional components or complex actuation systems.
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
Enables the efficient withdrawal of a column of washers in a single operation, improving packaging functionality and user convenience.
Implementation Method 1
the applied force is sufficient to flex a first lateral wall and a second lateral wall apart allowing the column of washers to pass therebetween

AI summary
Packaging for washer hardware products is provided along with a method of use. The packaging includes a semi-closed box having a pair of lateral walls with retainer beads near their upper ends. The packaging also includes a pair of end walls, one of which includes an opening for accessing the central hole of a column of washers contained therein. The column can be removed by inserting a rod through the central holes of the washers and lifting the rod upward while holding the packaging down, thereby forcing the washers between the retainer beads and through the open top of the box.
