Assortment Box with Angled Walls and Hook Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assortment boxes are not flexible enough for easy attachment and secure storage in transport and storage units, often occupying valuable space on workbenches and trolleys, and lack features for improved accessibility and legibility of contents.
Innovation Solution
The assortment box features a hook-shaped holding device for tool-free attachment to a retaining strip, an angled side wall design for improved accessibility and label legibility, and protrusions on the bottom for secure locking in transport units, along with a divider plate system and a simple lid attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the assortment box is placed on a workbench for storage, then it is easily accessible, but it occupies valuable workbench space needed for workpieces
Solution Approach 1:
The assortment box is equipped with a hook-shaped holding device that enables vertical suspension from retaining strips attached to walls or vertical surfaces. This transitions the storage dimension from horizontal (workbench surface) to vertical (wall-mounted suspension), making the workbench surface available for workpieces while keeping the assortment box easily accessible within arm's reach.
2Area of stationary object
If the assortment box is attached to a retaining strip, then workbench space is freed, but attachment requires additional components and complexity
Solution Approach 1:
The hook-shaped holding device is integrally formed as part of the assortment box structure during injection molding. This self-contained design eliminates the need for separate attachment components, reducing overall system complexity while enabling secure attachment to retaining strips. The holding device serves itself by providing both the attachment function and structural support.
3Ease of manufacture
If the side wall is vertical for simple manufacturing, then production is easier, but label legibility and accessibility are reduced
Solution Approach 1:
The side wall features a localized chamfered section with a specific angle (greater than 90° and less than 110°) that creates an inclined surface. This local geometric modification optimizes label legibility by angling the label surface toward the viewer while maintaining vertical side walls for the majority of the structure, thus preserving manufacturing simplicity while improving information visibility.
4Ease of operation
If the assortment box has a smooth bottom for easy part removal, then parts are easily accessed, but secure locking in transport units is compromised
Solution Approach 1:
The bottom surface is segmented into two distinct zones: a large smooth central area that facilitates easy part removal and access, and localized protrusions at specific positions that engage with corresponding recesses in transport units for secure locking. This segmentation allows both functions to coexist without compromise.
