Portable towel dryer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated towel dryers are inconvenient to use due to the hanging rod being close to the main machine, making it easy to bruise the user's hand when taking out or placing cloth.
Innovation Solution
A portable towel dryer with a lifting mechanism that adjusts the height of the supports for the hanging rod, allowing the rod to be lowered for easy handling and raised for drying, featuring a locking component and elastic member for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rack is integrated with the main machine and the hanging rod is positioned close to the main machine, then the device structure is compact and easier to mount, but it causes user injury risk when taking out or placing cloth
Solution Approach 1:
The patent applies the dynamics principle by making the support structure movable rather than fixed. The support can be extended outward from the main machine body and retracted back, allowing the hanging rod position to be dynamically adjusted. This resolves the contradiction by enabling the support to be retracted during cloth handling operations, eliminating the injury risk while maintaining the compact integrated structure for easy mounting.
2Volume of moving object
If the hanging rod is positioned close to the main machine, then the device structure is compact, but it is inconvenient for users to handle cloth
Solution Approach 1:
The support structure is designed to be dynamically extendable and retractable. During cloth handling, the support extends outward to provide adequate clearance for user access. When not in use, the support retracts to maintain a compact device profile. This dynamic adjustment resolves the contradiction between compactness and operational convenience.
3Ease of operation
If a lifting mechanism is added to adjust support height, then user convenience is improved, but device complexity increases
Solution Approach 1:
The lifting mechanism is designed to be manually operated by the user without requiring external power sources or complex control systems. The user can directly operate the lifting mechanism to extend or retract the support as needed. This self-service approach provides height adjustability while avoiding the complexity of motorized or automated systems.
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
Facilitates convenient use by allowing the height of the supports to be adjusted, reducing the risk of injury and improving usability when handling or drying cloths.
Implementation Method 1
