Pivoting Hold-Down Device for Cleaning Basket Item Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial dishwashing, light items such as plastic buckets or gastronorm containers often shift during cleaning due to water pressure, leading to inadequate cleaning and potential contamination, and traditional solutions like reducing water pressure or using weights are inefficient or impractical.
Innovation Solution
A cleaning basket system with a pivotally mounted hold-down device that acts on items from above to secure them within the basket, allowing for secure positioning without the need for external weights, which can be easily integrated into the basket system and adjusted for different items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If water pressure is reduced to prevent item displacement, then item stability is improved, but cleaning effectiveness deteriorates
Solution Approach 1:
A hold-down device is introduced as an intermediary mechanism between the items and the cleaning basket. This device applies localized downward force to counteract the upward water pressure on light items, allowing high water pressure to be maintained for effective cleaning while preventing item displacement through mechanical intervention.
Solution Approach 2:
The hold-down device functions as a counterweight mechanism, applying downward force to balance the upward force exerted by high-pressure water on lightweight items. This allows the system to maintain high cleaning pressure while preventing light items from being displaced during the cleaning process.
2Stability of the object's composition
If weights are used to prevent item displacement, then item stability is improved, but device complexity and operational burden increase
Solution Approach 1:
The hold-down device is merged with the cleaning basket structure, integrating the stabilization function directly into the basket. This eliminates the need for separate weights that would need to be manually handled, reducing operational complexity while maintaining item stability during cleaning.
Solution Approach 2:
The hold-down device is designed to automatically engage and disengage with the cleaning basket without requiring manual intervention. The device self-adjusts to maintain item stability during loading and cleaning operations, eliminating the need for operators to manually position or remove weights.
3Stability of the object's composition
If weights are used to secure items, then item stability is improved, but ease of operation deteriorates due to manual handling requirements
Solution Approach 1:
The hold-down device automatically engages with the cleaning basket and adjusts its position based on the items loaded. It self-activates during the loading process and self-disengages when the basket is removed from the cleaning chamber, eliminating all manual handling operations and significantly improving ease of use.
Solution Approach 2:
The hold-down device is designed with dynamic movement capabilities, allowing it to automatically adjust its position and engagement level based on the loading process and cleaning cycle. This dynamic behavior eliminates the need for static weights that require manual repositioning, greatly enhancing operational ease.
