Solution Overview
Problem
Conventional article-holding racks are difficult to fold or disassemble, leading to inconvenient storage and transportation due to complex construction, which increases production costs and user inconvenience.
Innovation Solution
A rack design featuring a foldable frame with removable shelves, where each shelf has a connecting bar and slats that fit into slots, and connectors that allow easy assembly and disassembly, enabling simple construction and efficient packing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional racks use complex construction to achieve stability and strength, then structural integrity is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The rack is divided into modular components including frame members, shelves, and connecting elements. Each shelf is separately constructed with slats fitting into slots on frame members, allowing independent assembly and disassembly of individual components while maintaining overall structural integrity through standardized connection points.
Solution Approach 2:
The rack employs movable and adjustable components such as shelves that can be easily inserted and removed from the frame. The connecting mechanism allows for dynamic reconfiguration, enabling users to assemble, disassemble, and reposition components based on storage needs without compromising the strength of the overall structure.
2Reliability
If conventional racks use complex construction to achieve stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The rack structure is segmented into standardized frame members and shelves with consistent slot and connector designs. This modular approach simplifies the overall construction complexity by using repeating components while maintaining stability through proper structural design of each module and their standardized connections.
Solution Approach 2:
The frame members and connectors are designed with universal compatibility, where the same slot and connector design can be used across different shelf configurations and positions. This universality reduces device complexity by eliminating the need for multiple specialized components while ensuring reliable and stable connections throughout the rack structure.
3Ease of operation
If conventional racks are designed for easy storage and transport, then ease of operation is improved, but manufacturing precision requirements worsen
Solution Approach 1:
By segmenting the rack into separate frame members and shelves with standardized connection interfaces, the design enables easy storage and transport of individual components. The slot and connector systems are designed with tolerance compensation features that maintain alignment precision during manufacturing while allowing for practical assembly variations in the field.

AI summary
A rack has a frame and a plurality of shelves. Each shelf has an enclosing frame member that has two first sides connected by two second sides, a connecting bar that connects the first sides at about the center of the first sides, a plurality of slots provided on the inner surfaces of the second sides, and a plurality of slats, each slat having opposing ends that are fitted into opposing slots at the second sides, and with each slat being connected to the connecting bar. At least one connector is provided for removably connecting each shelf to a portion of the frame.
