Extendable Guidance Device for Disc-Shaped Can Lids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guidance devices for disc-shaped can lids face challenges in changing their full length without compromising strength, as interference between guidance members can lead to reduced structural integrity.
Innovation Solution
The guidance device incorporates an extendable part with overlapping upstream and downstream guidance members, allowing for adjustment of the full length by moving these members along the conveyance direction, maintaining strength through solid construction and fixation with annular and flange-shaped members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If guidance members are arranged in line and moved to adjust the full length of the guidance device, then the adaptability of the device is improved, but the strength of the device is reduced due to hollow construction requirements
Solution Approach 1:
The patent applies nesting by allowing one guidance member to be inserted into another guidance member when adjusting the full length of the device. This nested configuration enables compact storage and flexible length adjustment without requiring hollow construction of the entire guidance device, thereby maintaining strength while achieving adaptability.
Solution Approach 2:
The guidance device incorporates movable guidance members that can be dynamically adjusted along the conveyance direction. This dynamic design allows the full length of the device to be changed according to different production requirements, improving adaptability while the members maintain solid construction to preserve strength.
2Ease of operation
If guidance members are moved along the conveyance direction to change device length, then the ease of operation is improved, but interference between guidance members occurs
Solution Approach 1:
The patent resolves interference issues by utilizing the radial dimension - guidance members are arranged radially around the conveyance path rather than linearly. This dimensional change allows members to move independently along the conveyance direction without interfering with each other, facilitating easy operation while preventing harmful interference.
Solution Approach 2:
The guidance device is segmented into multiple independent guidance members that can move separately. This segmentation allows each member to be adjusted independently along the conveyance direction, improving ease of operation while preventing interference between members through their distributed radial arrangement.
