Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of inhalers and electronic cigarettes, particularly cartomizers, there is a challenge in handling components automatically without damaging their external cylindrical surface and ensuring all components are oriented correctly for efficient processing in automated assembly or inspection lines, as they are often fed in randomly oriented states.
Innovation Solution
An apparatus and method that utilize optical sensors to detect the initial orientation of cartomizers, temporary support means with hinged support portions to reorient them, and handling means like vacuum grippers to transfer and align them correctly, ensuring all components are oriented in the same direction without damaging their external surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are fed in random orientation to automated processing lines, then feeding flexibility is improved, but processing reliability deteriorates due to incorrect orientation at work stations
Solution Approach 1:
The patent applies preliminary action by detecting the orientation of components before they reach the work station and pre-positioning them in the correct orientation during the transfer process. The sensor means detect orientation upstream, and the temporary support means with hinged support portions reorient components before final deposition, ensuring correct orientation is established in advance rather than correcting it at the work station.
2Extent of automation
If mechanical handling means are used to transfer components, then automation is improved, but risk of damaging the external cylindrical surface increases
Solution Approach 1:
The patent employs a vacuum field (a form of flexible energy field) instead of rigid mechanical contact for gripping and transferring components. The vacuum field gently holds the external cylindrical surface without mechanical pressure or friction that could cause scratches or damage, while still providing sufficient control for automated transfer and orientation.
Solution Approach 2:
The patent replaces traditional mechanical gripping systems with a vacuum field-based handling system. Instead of using mechanical fingers or clamps that physically contact and potentially damage the component surface, the vacuum field provides contactless holding and transfer, eliminating mechanical wear and surface damage risks while maintaining full automation.
3Manufacturing precision
If components are reoriented using complex mechanical mechanisms, then orientation precision is improved, but device complexity increases
Solution Approach 1:
The patent uses dynamic, movable support portions that can pivot between different angular positions rather than fixed mechanical orientation mechanisms. The hinged support portions can adaptively adjust to reorient components during transfer, providing precise orientation control through simple rotational movement rather than complex multi-axis mechanical systems.
