Removable Inner Door Panel for Soft Serve Machine Pump Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soft serve machines require frequent cleaning and sanitizing, which involves opening the cabinet door for extended periods, necessitating the relocation of the product mix to maintain temperature, making the process time-consuming and labor-intensive.
Innovation Solution
A soft serve machine design featuring a removable inner door panel that can be deployed to maintain a seal within the refrigerator cabinet, allowing access to product pumps while keeping the cold air inside, thus enabling cleaning without relocating the product mix.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cabinet door is opened for cleaning operations, then access to product pumps is enabled, but cold air is lost and product temperature cannot be maintained
Solution Approach 1:
The door system is segmented into an outer door and a removable inner door panel. The inner door panel can be detached and stored on the cabinet exterior, allowing the outer door to remain closed while still providing access to the product pumps through the openable inner panel section.
Solution Approach 2:
The removable inner door panel acts as an intermediary element between the closed cabinet door and the cleaning access requirement. It can be temporarily removed and stored on the cabinet exterior, serving as a mediator that allows door opening for cleaning while maintaining the overall sealed structure.
2Temperature
If the cabinet door remains closed during cleaning, then cold air is maintained, but access to product pumps for cleaning is blocked
Solution Approach 1:
The door assembly is divided into separable components - the inner door panel that provides cleaning access and the outer door that maintains thermal sealing. This segmentation allows the access function and sealing function to be independently optimized and operated.
Solution Approach 2:
The door system transitions from a static closed state to a dynamic configuration where the inner panel can be removed and stored on the cabinet exterior. This dynamic reconfiguration allows the system to adapt between maintaining seal integrity and providing cleaning access as needed.
3Ease of operation
If the inner door panel is removed for cleaning access, then product pump accessibility is improved, but cabinet sealing is compromised
Solution Approach 1:
The attachment structures are pre-positioned on the cabinet exterior before cleaning operations begin. The inner door panel can be directly attached to these pre-positioned structures, ensuring proper sealing alignment is achieved without requiring complex adjustment procedures during the cleaning process.
Solution Approach 2:
The attachment structures serve as intermediary elements that facilitate the transition of the inner door panel from the closed position to the stored position on the cabinet exterior. These structures ensure the panel maintains proper alignment and sealing contact throughout the movement and attachment process.
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
Enables efficient cleaning and sanitizing of soft serve machines while maintaining the product mix at a specified temperature, reducing the need for relocating the mix and minimizing labor and time required for the cleaning cycle.
Implementation Method 1
The inner door panel defines a seal relative to the refrigerator cabinet and cold air within the freezer compartment is maintained in the freezer compartment

AI summary
A soft serve dispensing machine includes a refrigerator cabinet. A door is hinged to the refrigerator cabinet. A freezer compartment is defined in the refrigerator cabinet and receives a soft serve product mix. Product pumps are linked with the soft serve product mix for moving the product to a dispensing portion of the soft serve dispensing machine. The product pumps are positioned proximate the front portion of the refrigerator cabinet and above the freezer compartment. A removable inner door panel is moveable between stored and deployed positions. In the deployed position, the door is in an open position and the inner door panel is attached to the refrigerator cabinet and defines a seal relative to the refrigerator cabinet and cold air within the freezer compartment is maintained in the freezer compartment while the product pumps are accessed.
