Shelf Support Repair Rail for Straightening Deformed Uprights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for repairing deformed supports or struts in shelves are costly and time-consuming, often requiring the removal of existing base plates and complete replacement of support frames, especially when minor damage occurs.
Innovation Solution
A method involving a repair and reinforcement set comprising a rail, counter-plates, and screws that can be attached to the support or strut without needing separate straightening, allowing for on-site assembly and adjustment to eliminate deformation, with washers and nuts providing additional stability and collision protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete replacement of the support frame is performed, then the structural integrity is restored, but the cost and time consumption increase significantly
Solution Approach 1:
The repair solution segments the support frame into deformable sections and rigid reinforcement sections. The reinforcement set (rails, counter-plates, screws) acts as a separate segment that can be attached only to the deformed area, avoiding complete replacement while restoring structural integrity.
Solution Approach 2:
The invention extracts only the necessary reinforcement components (rail, counter-plate, screws) from a complete support frame replacement solution. This allows repairing only the deformed section rather than the entire structure, reducing time and resource consumption.
2Reliability
If a complete replacement of the support frame is performed, then the structural integrity is restored, but the cost increases significantly
Solution Approach 1:
The reinforcement set uses relatively simple, easily replaceable components (standard rails, counter-plates, screws) that are cheaper than a complete support frame. These components can be manufactured at lower cost and provide sufficient reinforcement for the deformed area.
Solution Approach 2:
The reinforcement is applied locally only where deformation occurs, rather than reinforcing the entire support frame. The rail and counter-plate are positioned to provide targeted support at the deformed section, reducing material consumption and cost.
3Ease of repair
If existing base plates are removed for repair, then the repair can be performed, but the complexity and time of the repair process increase
Solution Approach 1:
The reinforcement set is designed to be pre-assembled or pre-positioned on the deformed section before final attachment. The rail can be positioned around the support and the counter-plate aligned with existing holes, allowing repair without removing base plates and reducing process complexity.
Solution Approach 2:
The reinforcement set components are designed with universal features (standard hole patterns, adaptable rail sections) that can be attached to various support frame configurations without requiring removal of existing base plates or custom fabrication.
4Manufacturing precision
If alignment aids are used for precise positioning, then the repair precision is improved, but the device complexity and processing effort increase
Solution Approach 1:
The reinforcement set components (rail, counter-plate) are designed with self-aligning features such as predetermined hole patterns that match standard support frame configurations. The components guide their own positioning through these pre-established alignment features, eliminating the need for separate alignment aids.
Solution Approach 2:
The alignment function is merged into the reinforcement components themselves through integrated hole patterns and geometric features. The rail and counter-plate include built-in alignment features that combine positioning and reinforcement functions, eliminating separate alignment aids.

AI summary
The invention relates to a method for repairing a deformed, especially vertical, support (1), or a horizontal or inclined brace (2, 3) of a shelf. There is at least one rail (5) surrounding the support (1) or the brace (2, 3) in the region of the deformation, and on the opposite side, at least one counter-plate (6) or washer to be screwed to the support (1) or the brace (2, 3) and the rail (5), or another rail (5) to be screwed to the first rail (5). The screwing process enables the support (1) or the brace (2, 3) to be straightened.
