Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goods-display shelves face issues with high manufacturing costs, complex assembly processes, and reduced durability due to the need for numerous parts and screws, as well as increased unit costs and space requirements for smooth movement of goods, especially when handling large loads or varying sizes.
Innovation Solution
The design incorporates L-, T-, and -type fixed frames with hook pieces and end caps that securely combine without bolts, allowing for easy assembly and adjustment of unit shelves, along with a separation device for convenient positioning and fixing, minimizing parts and enhancing air circulation and display effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If roller units are connected using fixing pins and fixing grooves, then the connection is secure, but the units cannot be separated and reassembled, increasing unit cost
Solution Approach 1:
The patent applies the dynamics principle by designing a snap-fit connection system that transitions from a static permanent connection to a dynamic reversible connection. The elastic deformation of the connecting portions allows the connection to be engaged and disengaged repeatedly, providing both strength during use and reassemblability when needed.
Solution Approach 2:
The patent uses elastic connecting portions as intermediaries between roller units and end caps. These elastic portions act as mediators that provide secure connection through elastic deformation while allowing reversible engagement, solving the contradiction between strong connection and reassemblability.
2Ease of operation
If the shelf slope is increased for smooth goods movement, then goods with large contact area move smoothly, but the manufacturing cost and structural complexity increase
Solution Approach 1:
The patent segments the shelf into modular units (roller units, end caps, support frames) that can be independently assembled and configured. This segmentation allows for simplified individual components with standard slopes, while the overall system achieves smooth goods movement through proper modular arrangement and connection mechanisms.
Solution Approach 2:
The patent changes the connection parameters between components (using elastic snap-fit connections with specific deformation characteristics) to achieve smooth goods movement without requiring excessive shelf slope. The elastic deformation parameters are optimized to provide both connection strength and movement facilitation.
3Adaptability or versatility
If multiple separate guide members are used to control space for each size of goods, then space control is achieved, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent implements universality by designing end caps and support frames that serve multiple functions: structural support, connection of roller units, and space control for different goods sizes. The elastic connecting portions provide both mechanical connection and adjustable positioning, eliminating the need for separate guide members for each goods size.
Solution Approach 2:
The patent merges the functions of connection and space control into single components. The end caps and support frames simultaneously provide structural connection and define storage spaces, while the elastic connecting portions enable both assembly and adjustable positioning, reducing the total number of parts needed.
4Device complexity
If roller units are arranged face-to-face continuously, then the structure is simple, but they separate under large loads
Solution Approach 1:
The patent applies dynamics by using elastic connecting portions that can dynamically respond to applied loads. The elastic deformation absorbs shock and distributes forces, allowing the simple face-to-face arrangement to maintain connection strength under large loads that would cause separation in rigid connections.
Solution Approach 2:
The elastic connecting portions provide beforehand cushioning by incorporating elastic deformation capability into the connection design. This pre-built elastic buffer protects against load-induced separation by absorbing and distributing mechanical stresses before they can cause connection failure.

AI summary
The present invention relates to a shelf for display of goods. More specifically, the present invention relates to a goods-display self in which improved are the structure of unit shelves composed by combining end caps with both ends of fixed frames accommodating roller units and the structure of front and rear support frames combined with both ends of the unit shelves. The said unit shelf not only can provide an easy space control to another unit shelf neighboring along front and rear support frames but also can fix set positions by using a stopper and can be separated conveniently by using a separation device.
