Feeder Cover Blocking Portion Prevents Rattling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing surface mount placement system feeders are prone to rattling during the manufacturing process due to insufficient pressure application when the rear cover is mistakenly pressed down before the front cover, resulting from the rear cover's free end being narrower than the distance between the front cover's sidewalls.
Innovation Solution
Incorporating a blocking portion on the rear cover that is wider than the distance between the front cover's sidewalls, ensuring the rear cover can firmly press the front cover and the strip, preventing rattling by ensuring correct operational sequence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the rear cover's free end is made narrower to fit within the front cover's sidewalls, then the assembly fits together, but the rear cover cannot effectively press down on the front cover when mistakenly pressed first, causing rattling
Solution Approach 1:
The blocking portion is designed to prevent the harmful action (pressing the rear cover first) before it can occur. When the rear cover is attempted to be pressed down first, the blocking portion protruding from the rear cover body interferes with the front cover's free end, physically preventing the incorrect pressing sequence and ensuring the front cover must be pressed first.
Solution Approach 2:
The blocking portion acts as an intermediary element between the rear cover and front cover. It mediates the interaction by providing a mechanical interference feature that ensures proper pressing sequence. The blocking portion transfers the pressing force correctly and prevents incorrect operation without requiring complex control systems.
2Force
If the blocking portion is made wider than the distance between sidewalls, then proper pressure is ensured, but the structure becomes more complex
Solution Approach 1:
The rear cover is segmented into distinct functional portions: the rear cover body and the blocking portion. This segmentation allows the blocking portion to be optimized for its specific function (providing mechanical interference and pressing force) without complicating the overall rear cover structure. The blocking portion is a simple protruding feature rather than a complex assembly.
Solution Approach 2:
The blocking portion is designed with local quality - it is wider than the distance between the front cover's sidewalls only at the critical interference region. This localized dimensional feature provides the necessary pressing force and mechanical interference without requiring the entire rear cover to be oversized or complex. The blocking portion's dimensions are specifically tailored to its function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents rattling and ensures proper pressure application during the manufacturing process by ensuring the rear cover's blocking portion interferes with the front cover, maintaining stability and accuracy.
Implementation Method 1
The rear cover pivotally installed on the feeder body comprises a blocking portion that interferes with the free end of the front cover. The blocking portion is wider than the distance between the sidewalls of the front cover.
Implementation Method 2
When the strip is fed, the front cover is placed upon the feeder body, pressing down on the rear cover, and as a result, the free end of the rear cover presses down on the second end of the front cover. As such, the rear cover has enough force to firmly press the front cover and the strip during the manufacturing process.

AI summary
A feeder for a surface mount placement system includes a feeder body comprising a shaft, a front cover, and a rear cover. The front cover has one end pivotally installed on the feeder body via the shaft, a free end, and a pair of sidewalls respectively extending from two sides of the free end towards the feeder body. The rear cover pivotally installed on the feeder body, including a blocking portion, and the free end of the front cover overlap. The blocking portion is wider than the distance between the sidewalls of the front cover.
