Bed base with locking corner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bed bases, particularly those extending from the box spring unit to the floor, are cumbersome to assemble and disassemble due to the complex arrangement of end and side panels coupled with bolts, washers, and wing nuts, resulting in high material and labor costs.
Innovation Solution
A corner locking mechanism is introduced, comprising a first and second section with orthogonal walls that secure side and end panels without the need for tools, using a retaining pin to hold the panels in place, allowing for efficient assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional corner connections with top plate, bottom plate, bolt, washer and wing nut are used, then structural stability is improved, but assembly time and disassembly time increase
Solution Approach 1:
The patent combines multiple separate components (top plate, bottom plate, bolt, washer, wing nut) into a single integrated corner piece that performs all fastening functions. This corner piece includes a body portion that attaches to one panel and a locking portion that secures the adjacent panel, eliminating the need for multiple separate parts and reducing assembly complexity.
Solution Approach 2:
The corner connection is divided into distinct functional segments: a body portion for attaching to the first panel and a locking portion for securing the second panel. This segmentation allows each part to perform its specific function efficiently while maintaining overall structural stability.
2Stability of the object's composition
If traditional corner connections with multiple parts are used, then structural stability is improved, but material cost increases
Solution Approach 1:
The patent consolidates five separate components (top plate, bottom plate, bolt, washer, wing nut) into a single integrated corner piece. This reduction in part count directly decreases material cost while maintaining structural stability through the unified design that incorporates all necessary fastening functions within one component.
3Stability of the object's composition
If traditional corner connections with multiple parts are used, then structural stability is improved, but labor cost increases
Solution Approach 1:
By merging multiple components into a single corner piece, the patent reduces the number of assembly steps and eliminates the need for multiple fastening operations. This simplification directly reduces labor cost while maintaining structural stability through the integrated design.
Solution Approach 2:
The corner piece is designed to be self-aligning and self-securing, where the locking portion automatically engages with the adjacent panel when the body portion is attached to the first panel. This self-service mechanism eliminates the need for complex assembly procedures and reduces labor requirements.
4Loss of time
If corner locking mechanism with fewer parts is used, then assembly time is reduced, but structural stability may be compromised
Solution Approach 1:
The integrated corner piece combines multiple fastening functions into a single component, ensuring that all necessary structural connections are made simultaneously. The body portion provides attachment to the first panel while the locking portion secures the second panel, maintaining structural stability through this unified approach.
Solution Approach 2:
The corner piece incorporates a retaining pin that can be inserted at various positions along the locking portion, allowing for adjustable structural stability based on specific application requirements. This parameter change capability enables the same corner piece to adapt to different stability needs while maintaining quick assembly.

AI summary
A corner locking mechanism for a bed base that has corners formed by respective adjacent mating side panels and end panels is provided. The corner locking mechanism has a first section including a first top wall, a first outer wall orthogonal to the first top wall, and a first inner wall extending orthogonally from the first top wall. The corner locking mechanism also has a second section extending orthogonally from the first section, the second section including a second top wall, a second outer wall extending orthogonally from the second top wall, and a second inner wall spaced from the second outer wall and extending orthogonally from the second top wall. The first section is located over one of the side panel or the end panel at the corners.
