Dryer Condenser Lid Pivot Structure for Easy Filter Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
State-of-the-art dryers face issues with condenser clogging due to particles from laundry, requiring frequent cleaning of filters and condensers, which complicates maintenance and reduces performance.
Innovation Solution
A dryer design featuring a pivoting lid that securely mounts and dismounts using two short shafts and a retainer system, allowing for easy access and cleaning of the condenser and filter, enhancing maintenance efficiency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is mounted to the body using traditional horizontal and vertical hookers, then the lid can be securely closed, but the mounting structure becomes complex and difficult to disassemble for maintenance
Solution Approach 1:
The patent divides the mounting function into separate components: the lid body, the housing, and the shaft. Instead of using a complex multi-point hooking system, the lid is segmented to include a simple shaft that rotates within the housing, allowing independent mounting and dismounting actions that simplify the overall structure.
Solution Approach 2:
The patent introduces dynamic movement to the mounting system by allowing the shaft to rotate within the housing. This rotational movement enables the lid to be easily mounted and dismounted without complex mechanical interlocking, transforming a static complex structure into a dynamic simple one.
2Reliability
If the lid is made securely mounted to prevent foreign matter entry, then reliability improves, but accessibility for maintenance of condenser and filter decreases
Solution Approach 1:
The patent uses a dynamically movable shaft that can rotate between a closed position (providing protection) and an open position (providing accessibility). This dynamic mechanism allows the same structure to fulfill both protective and maintenance functions without compromise.
Solution Approach 2:
The shaft acts as an intermediary element between the lid and the housing, mediating between the conflicting requirements of security and accessibility. By rotating the shaft, the user can transition between protected and accessible states without compromising either function.
3Device complexity
If a single full-length shaft is used to mount the lid, then the structure appears simple, but the shaft is vulnerable to damage and dislodging over time
Solution Approach 1:
The patent segments the single full-length shaft into multiple shorter shaft portions, each contained within its own housing. This segmentation prevents the shaft from being a long vulnerable element that can easily dislodge, while maintaining structural simplicity through the modular arrangement.
Solution Approach 2:
The patent provides beforehand protection by enclosing each shaft portion within a housing that prevents dislodging. This prior cushioning through structural enclosure ensures the shaft cannot easily become damaged or dislodged during normal operation.
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 design facilitates safe and durable mounting of the lid, reducing the risk of foreign matter entry and improving maintenance accessibility, extending the lifespan of the dryer components and simplifying the cleaning process.
Implementation Method 1
The shaft is received into the housing providing the lid to be pivotably mounted to the body by means of the shaft rotating on the housing
Implementation Method 2
The retainer is mounted to the connecting member preventing the shaft from dislodging
Implementation Method 3
The connecting member is mounted to the housing by inserting the shaft therethrough
