Chain Conveyor Bracket Reduces Sidebar Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paddle attachment brackets for chain conveyors cause stress and potential breakage of sidebars due to vertical welding, and suppliers do not warrant chains for such modifications, leading to structural integrity issues and inconsistency problems.
Innovation Solution
A chain conveyor paddle attachment bracket featuring a bent sheet of metal with perpendicular portions, including notches for welding to the sidebar and an opening for fastening paddles, which reduces stress on the sidebar and allows for articulation without obstruction, thereby enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If vertical welding is used to attach paddle brackets to chain sidebars, then the bracket can be securely attached, but the sidebar structural integrity is compromised and breakage risk increases
Solution Approach 1:
The bracket is divided into multiple segments (first portion with notches for welding, second portion perpendicular for paddle attachment) that distribute the attachment function across different locations, reducing concentrated stress on any single sidebar region while maintaining secure attachment
Solution Approach 2:
The bent sheet metal bracket acts as an intermediary element between the paddle and the chain sidebar, providing a distributed welding interface through notches that reduces stress concentration compared to direct attachment methods
2Ease of manufacture
If flat bracket material is used with vertical welding, then attachment is achieved, but inconsistency in material properties and structural integrity arises
Solution Approach 1:
The bracket transitions from a flat two-dimensional shape to a three-dimensional bent structure with perpendicular portions, creating multiple welding notches that provide more consistent and reliable attachment points while distributing structural load more evenly
3Strength
If vertical welds are applied to attach brackets, then attachment is achieved, but supplier warranty coverage is lost
Solution Approach 1:
The bracket design segments the attachment function into multiple notches distributed along the first portion, providing sufficient attachment strength through distributed welding points rather than relying on single-point vertical welds that void warranties
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 reduces the risk of sidebar breakage and maintains structural integrity by providing a secure welding interface and easy paddle attachment, ensuring consistent operation and compliance with supplier warranties.
Implementation Method 1
the two notches are configured to form a welding interface between the first portion of the bent sheet of metal and a sidebar of the chain link

AI summary
A chain conveyor paddle attachment bracket for coupling a paddle to a chain link is disclosed. In embodiments, the chain conveyor paddle attachment bracket includes a bent sheet of metal that forms a first portion and a second portion substantially perpendicular to one another. The first portion of the bent sheet of metal includes two notches on opposite sides of the first portion, wherein the two notches are configured to form a welding interface between the first portion of the bent sheet of metal and a sidebar of the chain link. The second portion of the bent sheet of metal includes an opening configured to receive a fastener for connecting the paddle to the second portion of the bent sheet of metal.
