Solution Overview
Problem
Conventional mold rotators are either expensive and complex with hydraulic or motorized systems, or simple and lacking a stabilizing system, leading to unsafe and hazardous inadvertent rotation when trying to disassemble or remove molds in a rotated position.
Innovation Solution
A simple and inexpensive L-shaped mold rotator with a stabilizing system that automatically rotates 90° and stabilizes in either position using a curved base and L-shaped legs, with a fluid transfer system to redistribute weight and prevent inadvertent rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple mold rotator without complicated systems is used, then cost and complexity are reduced, but the mold rotator cannot be stabilized in a rotated position leading to unsafe self-rotation
Solution Approach 1:
The patent applies the counterweight principle by using a stabilizing weight that can be positioned to counterbalance the mold's weight. When the mold rotator is rotated to a desired position, the stabilizing weight is moved to create a counterbalancing moment that prevents self-rotation back to the original position, thus providing stability without requiring complex hydraulic or motorized systems
Solution Approach 2:
The patent uses a stabilizing mechanism as an intermediary between the mold and the rotator base. This stabilizing mechanism includes components that engage with the rotator base to lock or hold the rotated position, acting as a mediator that transfers and maintains the positional state without requiring continuous power or complex control systems
2Ease of operation
If hydraulic or motorized systems are used to rotate the mold, then the mold can be rotated and positioned, but the system becomes expensive and complicated
Solution Approach 1:
The patent applies the self-service principle by designing a mold rotator that uses the mold's own weight to drive the rotation process. The mold is lowered onto the rotator, and its weight automatically causes the rotator to rotate to a stable position without requiring external motors or hydraulic systems. The system essentially uses itself (the mold's weight) to perform the work of rotation
Solution Approach 2:
The patent uses the equipotentiality principle by designing the rotator with a curved base that creates multiple stable equilibrium positions. The mold rotator system naturally seeks these equipotential positions where the center of gravity is at its lowest point, allowing the mold to be easily rotated and held at various positions without requiring continuous energy input or complex positioning mechanisms
3Ease of manufacture
If the mold rotator lacks a stabilizing system, then it is simpler and cheaper, but the mold cannot be safely disassembled or removed due to inadvertent rotation
Solution Approach 1:
The stabilizing weight positioned to counterbalance the mold prevents harmful self-rotation during disassembly and removal operations, eliminating the safety hazard while keeping the overall system simple and cost-effective
Solution Approach 2:
The stabilizing mechanism provides prior cushioning by being pre-positioned to prevent inadvertent rotation before it can cause harm. The stabilizer is ready in advance to counteract any forces that might cause self-rotation, ensuring safety throughout the mold disassembly and removal process

AI summary
A mold rotator with a first section and a second section that are engaged approximately perpendicularly to each other to produce a base and an L-shaped platform for receiving the article. The base of the article rotator may have a curved section at the intersection of the first section and the second section and the article rotator may rotate on its curved section between a first position wherein the article rotator is supported on its first section and a second position wherein the article rotator is supported on its second section. Further, the article rotator allows an article to be safely rotated simply by lowering the article onto the article rotator so that the article rotator automatically rotates approximately 90° from a first position and a second, rotated position. The article rotator may include a stabilizing system.
