Solution Overview
Problem
Conventional mattress cleaning machines with cylindrical inner containers are ineffective in cleaning mattresses due to their structure, which fails to accommodate multiple mattresses efficiently and poses issues during loading and unloading.
Innovation Solution
A mattress cleaning machine with a cuboid inner container that allows multiple mattresses to be placed and features a positioning device for stable loading and unloading, equipped with telescopic cylinders and a brake device for controlled rotation, and photoelectric sensors for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cylindrical inner container is used, then the structure is simple, but it cannot effectively clean mattresses and cannot accommodate multiple mattresses
Solution Approach 1:
The inner container is divided into multiple cabins (first cabin, second cabin, third cabin, fourth cabin) arranged in a cuboid structure, allowing separate placement and cleaning of multiple mattresses simultaneously. Each cabin can independently accommodate a mattress, increasing productivity while maintaining manageable structural complexity through modular design
Solution Approach 2:
The inner container changes from a cylindrical shape to a cuboid shape with multiple levels and cabins arranged in vertical and horizontal dimensions. This dimensional reorganization allows efficient space utilization for multiple mattresses while enabling effective cleaning contact surfaces
2Ease of operation
If the inner container rotates for cleaning, then cleaning coverage is improved, but the cabin door position becomes inconvenient for loading and unloading
Solution Approach 1:
The positioning device is activated before the rotation cleaning process begins to ensure the cabin door is precisely positioned at the sealing door location. This preliminary positioning action guarantees that mattresses remain securely contained during rotation while maintaining loading/unloading convenience when the door is open
Solution Approach 2:
The sealing door acts as an intermediary between the cabin door and the rotating inner container. The positioning device aligns the cabin door with the sealing door position, creating a reliable interface that maintains mattress containment during rotation while allowing convenient access during loading and unloading operations
3Ease of operation
If the cabin door is opened for loading and unloading, then accessibility is improved, but mattresses may become displaced during rotation
Solution Approach 1:
The system dynamically adjusts the cabin door position based on operational phase: during loading and unloading, the door is open for accessibility; during rotation cleaning, the positioning device secures the door at the sealing door position to prevent mattress displacement. This dynamic control balances accessibility and stability requirements
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 simultaneous cleaning of multiple mattresses while ensuring stable loading and unloading, preventing mattress displacement during rotation, and facilitating efficient cleaning operations.
Implementation Method 1
telescopic cylinders are respectively provided below the positioning piece at two sides of an axial center of the positioning pole; when the two telescopic cylinders extend at the same time and bear against the same positioning piece, the cabin door reaches the position of the sealing door
Implementation Method 2
a brake disc is coaxially fixedly mounted to a side of the positioning pole close to the horizontal cylinder, and one side of the brake disc is mounted with a brake device
Implementation Method 3
photoelectric sensors are mounted to two sides of the positioning pole respectively; a photoelectric reflecting plate is mounted to the brake disc, and when the photoelectric sensor receives a signal of the photoelectric reflecting plate, the telescopic cylinder starts to drive
