Metalworking Carousel Rigidity via Dual Upright Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for working metallic bodies, such as aerosol cans, often lack sufficient rigidity and require expensive solutions to ensure correct relative motion between the supporting frame and the elongated element, complicating the fitting and increasing production costs.
Innovation Solution
The apparatus incorporates a supporting frame with two lateral uprights and angularly spaced guiding elements between the uprights and the longitudinal element, along with adjustment guides to facilitate smooth and rigid movement of the front table and carousel, allowing for reliable and cost-effective plastic deformation of metallic bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a footing that supports the elongated element in a cantilever arrangement is used, then the apparatus structure is simplified, but sufficient rigidity is not ensured
Solution Approach 1:
The supporting frame is divided into two separate lateral uprights instead of a single cantilever footing. Each upright independently supports one end of the elongated element, distributing the mechanical loads and preventing the rigidity issues associated with cantilever structures while maintaining structural simplicity.
Solution Approach 2:
The support structure transitions from a single-point cantilever support (one-dimensional simplification) to a distributed two-point support system (two-dimensional arrangement). This dimensional change provides bilateral support that eliminates the inherent rigidity problems of cantilever arrangements.
2Strength
If two lateral uprights are provided to support the elongated element, then rigidity is improved, but expensive bearings and complicated fitting are required
Solution Approach 1:
The elongated element itself serves as the guiding mechanism for the front table's movement. By providing guiding portions integrated into the elongated element, the system eliminates the need for separate expensive bearings and complex fitting arrangements, achieving self-guidance through the structural design.
Solution Approach 2:
The guiding function is merged into the elongated element structure itself rather than being a separate component. The guiding portions are integral to the elongated element, combining the support and guidance functions into a single structural element that reduces complexity and cost.
3Manufacturing precision
If expensive bearings are provided to ensure relative movement, then movement precision is improved, but production cost increases
Solution Approach 1:
The system uses self-guidance through integrated guiding portions on the elongated element rather than expensive external bearings. The structural design itself provides the precise movement guidance needed, eliminating costly bearing components while maintaining manufacturing precision.
Solution Approach 2:
The invention replaces expensive, complex bearing assemblies with simpler, more cost-effective guiding structures that achieve the same functional result. The guiding portions are straightforward mechanical features that are much cheaper to manufacture than precision bearings.
