Shelf Support Stop Member for Higher Load and Adjustability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf supports often impair access to spaces above and below the shelf, have limited adjustability, and insufficient load capacity due to bending and disengagement from apertured wall members.
Innovation Solution
The introduction of a stop member within the shelf support design that limits deflection, preventing premature release from the wall member and enhancing load transfer, thereby increasing the load capacity and adjustability of shelving assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shelf supports are made adjustable for use at multiple heights, then adaptability is improved, but device complexity increases due to the need for engagement mechanisms with apertured wall members
Solution Approach 1:
The shelf support employs a resilient body that can dynamically deflect and bend to engage with apertures at different heights. The resilient nature allows the support to adapt to various positions while maintaining structural integrity, providing adjustability without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The shelf support changes its physical state by deflecting and bending to different degrees depending on the required height adjustment. By varying the deflection parameter, the same support structure can engage with apertures at multiple heights, achieving adaptability through parameter variation rather than multiple fixed configurations.
2Ease of operation
If shelf supports are designed to be readily adjustable, then ease of operation is improved, but reliability deteriorates due to premature release from wall members
Solution Approach 1:
The stop member is positioned beforehand to prevent excessive deflection of the resilient body. By limiting the maximum deflection distance, the stop member ensures that the shelf support maintains sufficient engagement force with the wall member, preventing premature release while still allowing easy adjustment within safe limits.
Solution Approach 2:
The stop member provides a preliminary counteracting force against the deflection of the resilient body. This preliminary anti-action prevents the deflection from exceeding the threshold that would cause disengagement, thereby maintaining reliability while preserving ease of operation for normal adjustments.
3Ease of operation
If shelf supports allow greater deflection for adjustment, then ease of operation is improved, but load capacity deteriorates due to bending and disengagement
Solution Approach 1:
The stop member performs a preliminary action by limiting deflection before excessive bending can occur. This preliminary constraint ensures that the resilient body remains within its elastic range, maintaining its load-bearing capability while still allowing sufficient deflection for easy adjustment operations.
Solution Approach 2:
The stop member establishes an optimal parameter range for deflection that balances ease of operation with load capacity. By constraining the deflection parameter within specific limits, the system achieves adjustable operation while maintaining the structural integrity and load-bearing strength of the shelf support.
4Strength
If shelf supports are made more robust to increase load capacity, then strength is improved, but access to spaces above and below shelf deteriorates due to obstruction
Solution Approach 1:
The shelf support utilizes a thin, resilient body that provides sufficient strength through elastic deformation rather than through bulky rigid structures. This flexible design maintains load capacity while occupying minimal space, thereby preserving access to the areas above and below the shelf without obstruction from robust structural elements.
Solution Approach 2:
The resilient body changes its physical parameters by deflecting under load rather than requiring increased structural mass. This parameter-based strength mechanism allows the support to maintain high load capacity with a compact profile, ensuring that access to spaces above and below the shelf remains unobstructed.
