Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby cribs are difficult to assemble and disassemble efficiently, often requiring mechanical fasteners that can be lost or misplaced, and lack adjustable height settings and effective locking mechanisms for stability.
Innovation Solution
A baby crib design featuring side and end panels that can be assembled tool-free, with slidable connections and detachable support members allowing for adjustable height, and locking members with notches and protrusions for enhanced stability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical fasteners such as screws, nuts or bolts are used to secure components together, then the structural strength and stability of the crib is improved, but the ease of assembly and disassembly deteriorates due to the need for tools and the risk of losing small components
Solution Approach 1:
The patent replaces traditional mechanical fasteners (screws, nuts, bolts) with a cam-based locking mechanism. The cam lever provides mechanical advantage through its curved surface, allowing users to secure components with simple lever motion rather than threading fasteners. This substitution maintains structural strength while dramatically improving ease of assembly and disassembly.
Solution Approach 2:
The cam locking mechanism is designed to be self-retaining, where the cam's curved geometry automatically maintains the locked position without requiring additional fasteners or tools. The mechanism serves itself by using the cam's shape to provide both the locking action and the mechanical advantage needed to maintain security, eliminating the need for separate fastening components.
2Adaptability or versatility
If adjustable height settings are added to the crib, then the adaptability and versatility are improved, but the device complexity increases due to additional components and assembly steps
Solution Approach 1:
The patent implements adjustable height settings by making the support members dynamically repositionable along the side panels. The cam locking mechanism allows support members to be easily moved between different height positions and securely locked in place. This dynamic design provides adaptability without significantly increasing complexity, as the same locking mechanism used for assembly also enables height adjustment.
3Productivity
If tool-free assembly is implemented, then the ease of operation and productivity are improved, but the reliability and stability may deteriorate due to simpler connection mechanisms
Solution Approach 1:
The cam lever acts as an intermediary mechanism that translates simple user motion into a secure locked position. The cam's curved geometry provides mechanical advantage, allowing a small input force to generate a large locking force that ensures reliable component securing. This intermediary mechanism bridges the gap between simple tool-free operation and robust stable connection.
Solution Approach 2:
The cam locking mechanism is pre-configured with its curved geometry to automatically provide the necessary mechanical advantage and locking force. The design incorporates the stability-enhancing features into the basic locking action itself, so that the preliminary design work ensures reliability without requiring additional complex components or assembly steps during use.

AI summary
A baby crib includes a plurality of panels coupled together and having a pair of side panels and a pair of end panels. The side panels are oriented generally parallel relative to one another with each side panel having a top edge, a bottom edge, a first side edge and a second side edge. The pair of end panels include a first end panel slidably mounted to the side panels proximate the first side edges and a second end panel slidably mounted to the side panels proximate the second side edges. A plurality of support members are detachably coupled to the pair of side panels and are able to support a platform. Each support member is coupled to the side panels in one of a plurality of height positions. The plurality of support members are designed to support a mattress.
