Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closing machines with ejection devices experience increased wear and energy consumption due to sliding movements, leading to frequent replacements and complex lubrication challenges.
Innovation Solution
The closing machine employs a rotatable rolling body sliding element that moves in a rolling motion along the sliding profile, allowing free rotation around two axes, reducing wear and improving lubricity, with a bearing element and spring element for enhanced performance and simplified lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding element performs sliding movement along the sliding profile, then the ejection head can be moved along the sliding profile to hold and eject containers, but wear on the sliding profile and sliding element increases significantly
Solution Approach 1:
The sliding element is designed as a rotatable rolling element (sphere or ball) instead of a conventional sliding component. This spherical shape enables rolling motion along the sliding profile, transforming the friction mechanism from sliding friction to rolling friction, thereby dramatically reducing wear on both the sliding profile and the sliding element itself.
Solution Approach 2:
The sliding element is made rotatable around its support axis during operation. This dynamic rotation converts the static sliding contact into dynamic rolling contact, allowing the ejection head to move along the sliding profile while the rolling element continuously rotates, minimizing wear and extending component service life.
2Productivity
If sliding movement is used along the sliding profile, then the ejection device can function, but energy consumption increases due to friction
Solution Approach 1:
By employing a spherical rolling element instead of sliding contact, the invention converts high-friction sliding motion into low-friction rolling motion. This reduction in friction directly decreases the energy required to move the ejection head along the sliding profile, lowering overall energy consumption while improving operational smoothness.
3Object-generated harmful factors
If a lubricating film is used between the sliding element and sliding profile, then friction is reduced, but the lubrication system becomes complex and the film may break
Solution Approach 1:
The invention replaces the lubrication-dependent sliding friction system with a rolling friction system. By using the rotatable rolling element, the patent substitutes the need for complex lubrication films with a mechanical rolling mechanism that inherently generates less friction and does not require sophisticated lubrication infrastructure.
4Manufacturing precision
If sliding movement is used, then the ejection head can be positioned accurately, but vibrations increase due to wear and friction
Solution Approach 1:
The rotatable rolling element introduces dynamic motion that smooths the interaction between the ejection head and sliding profile. The continuous rotation absorbs shocks and reduces vibrations compared to rigid sliding contact, while the rolling mechanism maintains precise positioning capability through controlled movement along the profile.
