Scraper Assembly With Spring-Loaded Pin For Blending Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scraper assemblies in commercial blending and cooking systems face issues such as contamination, reduced productivity due to food residue, complex designs that require special tools for maintenance, and inadequate contact between scraper heads and tub surfaces, leading to uneven scraping and sticking.
Innovation Solution
A scraper assembly design featuring a substantially rigid member, a pin with a tab, a scraper head with specific channels to accommodate the pin, and a coil spring held captive between the rigid member and the scraper head, allowing for secure attachment and easy removal, ensuring consistent contact with the tub surface and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional scraper assemblies are used, then scraping function is provided, but food residue accumulates in spaces requiring deconstruction for cleaning
Solution Approach 1:
The scraper assembly is divided into separable components including the scraper head, pin, and rigid member that can be easily detached from each other. This segmentation allows the scraper head to be removed for cleaning without deconstructing the entire assembly, eliminating food residue accumulation in hard-to-reach spaces while maintaining the scraping function.
2Reliability
If scraper assemblies are designed with secure attachment, then scraping effectiveness is improved, but removal and replacement becomes difficult
Solution Approach 1:
The attachment mechanism uses a dynamic design where the pin can be easily inserted and removed from the scraper head through aligned holes, and the rigid member can be detached from the pin. This dynamic configuration provides secure attachment during operation to ensure scraping effectiveness, while allowing quick removal and replacement of components for maintenance without requiring special tools.
3Manufacturing precision
If scraper heads are designed to maintain constant contact with tub surface, then scraping uniformity is improved, but complexity of attachment mechanism increases
Solution Approach 1:
The scraper head is designed with a predetermined curvature that matches the tub surface geometry, and the attachment mechanism pre-positions the scraper head to maintain optimal contact. This preliminary design ensures uniform scraping across the tub surface without requiring complex active adjustment mechanisms, achieving scraping precision through geometric design rather than complex control systems.

Function Achieved in This Case
The design enhances scraping efficiency, reduces contamination, and simplifies maintenance by maintaining consistent contact with the tub surface and allowing for easy replacement of components, thereby improving productivity and hygiene in blending systems.
Implementation Method 1
a coil spring, wherein the coil spring is disposed around the pin and is held captive between the substantially rigid member and the scraper head

AI summary
Certain embodiments of the present invention provide a scraper assembly. For example, in one embodiment, a scraper assembly comprises: a substantially rigid member; a pin with a first end and a second end, wherein a tab protrudes from a side of the first end and the second end is attached to the substantially rigid member; a scraper head with a hole therethrough that is large enough to receive the pin, wherein the scraper head has a first channel that runs the depth of the scraper head and is large enough to receive the tab, and wherein the scraper head has a second channel that does not run the depth of the scraper head and is large enough to receive the tab; and a coil spring, wherein the coil spring is disposed around the pin and is held captive between the substantially rigid member and the scraper head.
