Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass tube forming devices in forming machines for medical containers face issues with external oil and air tubes obstructing visibility, requiring precise pressure control, and are not compact or efficient in operation.
Innovation Solution
The forming device integrates lubrication and cooling channels and ducts within the support arms, allowing deforming discs to hang downwards, utilizing gravity for lubrication and cooling, eliminating external tubes and enhancing visibility and reducing pressure requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external tubes for oil and air are provided to lubricate and cool the deforming disc, then the deforming disc can be properly lubricated and cooled, but the tubes obstruct the vision of the working area and create construction difficulties
Solution Approach 1:
The patent integrates the lubrication and cooling channels directly into the support arm structure itself, merging the function of separate external tubes with the structural component. The support arm contains internal passages that deliver oil and air directly to the deforming disc, eliminating the need for external tubing while maintaining all necessary lubrication and cooling functions.
Solution Approach 2:
The lubrication and cooling channels are nested within the support arm structure. The internal passages are embedded in the arm's body, with outlets positioned near the deforming disc. This nesting approach allows the delivery system to be contained within the existing structural component, removing external tubes and improving visibility of the working area.
2Reliability
If pressurized tubes are used to feed oil and air onto the deforming discs, then adequate lubrication and cooling can be achieved, but precise pressure control is required and the system becomes more complex
Solution Approach 1:
The support arm structure itself serves as the delivery system for lubrication and cooling. By integrating the channels directly into the arm, the system eliminates the need for complex external pressure control mechanisms. The gravity-assisted oil delivery and simplified air cooling reduce the need for precise pressurization, making the system easier to operate and maintain.
3Strength
If deforming discs are mounted on arms with external tubes, then the structure can support the discs, but the overall device size increases and compactness is reduced
Solution Approach 1:
The support arm and the lubrication/cooling delivery system are merged into a single integrated component. The arm structure contains internal channels that eliminate the need for separate external tubes, reducing the overall device volume while maintaining full structural support capability for the deforming discs.
Solution Approach 2:
The delivery channels are nested within the support arm structure, allowing the functional elements to be contained within the existing structural volume. This nesting approach maintains structural integrity while eliminating external components that would increase device size, achieving a more compact overall configuration.
