Solution Overview
Problem
Existing presentation solutions for rotary clothes dryers are hindered by limited space, high costs, susceptibility to corrosion or moisture, and inflexibility, leading to frequent replacements and high transport costs, making it difficult to securely display and easily remove the products.
Innovation Solution
A modular support frame with receiving tubes and fastening elements, made from recycled plastic, allowing for secure fixation and easy removal of elongated objects, with dimensions optimized for logistics and adaptable to different sizes through dovetail connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal frames or wooden frames are used to securely display rotary clotheslines, then the products are stable and secure, but the frames are heavy, expensive, and susceptible to corrosion or moisture damage
Solution Approach 1:
The patent changes the material parameter from traditional metal or wood to a lightweight composite material that provides sufficient mechanical strength while reducing weight and corrosion susceptibility. The support frame uses a optimized structural design with vertical supports and horizontal beams that maintains stability with reduced material mass.
Solution Approach 2:
The patent employs composite materials for the support frame structure, combining materials that offer both mechanical strength and resistance to environmental factors. The frame structure integrates multiple material properties to achieve stability without the weight and corrosion issues of traditional metal or wooden frames.
2Reliability
If complex compartments and securing mechanisms are added to prevent clotheslines from falling, then the display becomes more secure, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the essential securing function from complex compartment structures and implements it through simple horizontal beams that rest on the rotary clotheslines. This removes unnecessary structural complexity while maintaining the security function through a minimalistic beam-based retention system.
Solution Approach 2:
Instead of using complex compartments to hold the clotheslines, the patent inverts the approach by using simple horizontal beams that rest on top of the clotheslines, allowing the clotheslines themselves to support the beams. This simplifies the overall structure while maintaining security.
3Stability of the object's composition
If rigid display boxes with fixed compartments are used, then the structure is stable, but the adaptability to different space sizes is reduced
Solution Approach 1:
The patent divides the display structure into modular components: vertical supports, horizontal beams, and base elements that can be independently assembled. This segmentation allows the display to be configured in different arrangements (single unit, dual units, or multi-unit configurations) while maintaining structural stability through standardized connection points.
Solution Approach 2:
The patent introduces dynamic adaptability through adjustable horizontal beams that can be positioned at different heights and locations on the vertical supports. This allows the display structure to adapt to different space requirements and product display needs while maintaining overall structural integrity.
4Reliability
If high securing mechanisms like waist-high beams or chains are used to prevent tipping, then the display is more stable, but the ease of customer removal deteriorates
Solution Approach 1:
The patent uses horizontal beams that extend only partially across the display width, providing sufficient anti-tipping stability through strategic placement rather than full-width coverage. The beams are positioned to engage with the upper portion of the rotary clotheslines, providing adequate retention without creating high barriers that would complicate customer removal.
