Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional showcase roller shelves face challenges in productivity and assembly efficiency due to misalignment of roller units, which affects the smooth sliding of goods and requires frequent replacement of rollers.
Innovation Solution
The end cap for a showcase roller shelf features a design with protrusions of varying lengths across columns, ensuring that each roller unit has a unique rotation center position, allowing for increased contact area and efficient sliding of goods while using standardized rollers across columns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If roller units are arranged in alignment in a single column, then assembly is simplified, but contact area with goods is reduced and sliding efficiency decreases
Solution Approach 1:
The patent transitions from a single-column aligned arrangement to a multi-column misaligned arrangement, adding spatial dimensionality to the roller configuration. This dimensional change increases the contact area with goods while maintaining assembly simplicity through standardized end cap components.
Solution Approach 2:
The end cap employs asymmetric protrusion lengths on different sides to create misaligned roller positions across multiple columns. This asymmetric design enables varied roller center axis positions that increase contact area with goods, while the protrusions themselves remain symmetric in structure for ease of manufacturing.
2Productivity
If roller units are misaligned in multiple columns to increase contact area, then sliding efficiency improves, but assembly complexity increases
Solution Approach 1:
The end cap is designed as a universal component that simultaneously supports multiple rollers in misaligned columns. By integrating multiple protrusions of different lengths into a single end cap structure, the patent achieves complex misaligned positioning without requiring multiple different components, thus simplifying assembly while maintaining high sliding efficiency.
Solution Approach 2:
The patent varies the protrusion length parameter of the end cap to achieve different roller center axis positions across multiple columns. By changing only the protrusion length parameter while keeping the overall end cap structure standardized, the system achieves misaligned roller arrangements that improve sliding efficiency without significantly increasing assembly complexity.
3Ease of operation
If protrusions of varying lengths are used in end caps to create misalignment, then roller center axis positions are optimized for sliding, but end cap manufacturing complexity increases
Solution Approach 1:
The end cap employs local quality variation through protrusions of different lengths at specific positions, while the overall end cap structure and material remain standardized. This localized variation in protrusion length achieves the required misalignment for smooth sliding without requiring complex manufacturing processes for the entire end cap component.
Solution Approach 2:
The patent changes the protrusion length parameter at different locations on the end cap to create misaligned roller positions. By varying only this single geometric parameter while maintaining the same end cap base structure and material, the system achieves optimized sliding smoothness without significantly increasing manufacturing complexity.
