Nested Label Housing for Container Collar Shoulder Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for fixing identification labels on pots or containers create protrusions that hinder mechanized handling, particularly for cylindrical pots, due to shape discontinuities at the connection between the collar and the body, leading to handling issues with forks used in automated systems.
Innovation Solution
The design involves a slot or housing with a greater draft angle at the collar than the pot body, ensuring continuity of the shoulder shape and allowing for improved interlocking and stacking without modifying the pot's main dimensions, by adjusting the clearance angles of the collar and body to facilitate easier handling and identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a housing or casing is made on the container wall to fix the label, then the label fixation is improved, but a protrusion is created that hinders mechanized handling
Solution Approach 1:
The housing is nested within the collar structure, utilizing the collar's thickness and internal space to contain the label fixation mechanism. The housing is positioned such that its outer surface does not protrude beyond the collar's outer surface, allowing handling forks to engage with the collar without obstruction while maintaining secure label fixation within the nested housing structure.
2Reliability
If the housing height corresponds to the collar height, then the label fixation is secure, but shape discontinuities are created at the shoulder level
Solution Approach 1:
The housing is designed with localized dimensions that differ from the collar: its height is less than the collar height, and its width is less than the collar width. This local variation in dimensions allows the housing to be securely integrated into the collar structure for reliable label fixation while maintaining the overall continuity of the collar's outer surface and shoulder shape for mechanized handling.
3Reliability
If the housing width equals the distance between collar and pot body, then the label fixation is optimized, but handling forks cannot engage properly
Solution Approach 1:
The housing is nested within the collar's cross-sectional area, utilizing the space between the collar's inner and outer surfaces. The housing width is designed to be less than the collar width, allowing it to fit within the collar's lateral boundaries. This nesting arrangement optimizes label fixation within the available space while preserving the collar's full width for proper engagement by handling forks.
4Ease of operation
If a concavity is made in the collar to accommodate the housing, then the protrusion problem is reduced, but shape discontinuities remain at the shoulder
Solution Approach 1:
The concavity is designed as a localized feature within the collar structure, with specific dimensions that allow the housing to be accommodated without creating external protrusions. The concavity's depth and width are carefully controlled to maintain the collar's outer surface continuity at the shoulder level, ensuring that handling forks can engage with the collar without encountering shape discontinuities while still providing adequate space for secure label fixation.

AI summary
The device has a chromo case extending on width of a flange ring (6) of a pot (1). The ring has an external straight section greater than that of a pot body (7), where the junction between the body and ring is formed by an annular radial shoulder (8). A flexible flat portion of an object is engaged in a passage passing through the ring. The passage emerges, via a lower orifice (12), from a concavity (10) formed in the ring above the shoulder. The concavity has a base extending between the orifice and shoulder with respect to a main axis of the pot along a slope lower than that of the ring.
