Solution Overview
Problem
Conventional keyrings are inconvenient to use due to their complex structure and require significant manual assembly, leading to increased material and processing costs.
Innovation Solution
An integrally formed, resilient, plate-shaped holder with first and second holding grooves and insertion ports that can be easily opened by applying external force, allowing items to be inserted and removed without complex assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional keyrings use a circular ring body made of resilient metal material wound several times, then the keyring is easy to manufacture and cost-effective, but the user has to open the circular ring body with great strength and repeat several times before successfully inserting a key
Solution Approach 1:
The holder is divided into multiple independent holding grooves (first holding groove, second holding groove) that can accommodate different items separately. Each groove has its own insertion port and limiting block, allowing independent access and organization of keys, loops, and other items without interfering with each other.
Solution Approach 2:
The holder utilizes the resilient nature of the plate-shaped body to create dynamically accessible insertion ports. When force is applied to the first end portion, the plate deforms elastically to open the insertion port, allowing easy insertion of items. The limiting blocks can also be pressed to release items, providing dynamic control over item access.
2Adaptability or versatility
If keyrings use multiple structural components such as limiting blocks, pivot holes, pivot shafts, and elastic elements, then the keyring can achieve flexible assembly and disassembly, but the structure becomes overly complex and increases material and processing costs
Solution Approach 1:
Multiple functional components are merged into a single integrally formed plate-shaped body. The holder combines the functions of the container body, limiting blocks, holding grooves, and elastic elements into one monolithic structure made from a single sheet of resilient material, eliminating the need for separate parts and manual assembly.
Solution Approach 2:
The plate-shaped holder is designed as a universal container that can hold various types of items including keys, loops, bead chains, and hooks. The multiple holding grooves and insertion ports provide versatile functionality for organizing different items, while the integral structure maintains simplicity.
3Adaptability or versatility
If keyrings use multiple structural components and manual assembly, then the keyring can achieve flexible assembly and disassembly, but the production process becomes more labor-intensive and cost-ineffective
Solution Approach 1:
Multiple functional components are merged into a single integrally formed plate-shaped body. The holder combines the functions of the container body, limiting blocks, holding grooves, and elastic elements into one monolithic structure made from a single sheet of resilient material, eliminating the need for separate parts and manual assembly.
Solution Approach 2:
The holder is designed to be self-forming through its resilient plate structure. The integral design allows the holder to automatically provide its functional features (holding grooves, limiting blocks, insertion ports) without requiring external assembly operations, thereby increasing production efficiency.
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 holder provides a simple, durable, and cost-effective solution for stably holding multiple keyrings, loops, and hooks, with easy attachment and detachment of items.
Implementation Method 1
an integrally formed resilient plate-shaped body, extending from a first end portion through a first folded section and a second folded section and terminated at the second end portion, thus constituting a movable space

AI summary
The invention relates to a holder integrally formed in the form of a flat, hollow plate-shaped case. At least one first holding groove is formed between a first end portion and a first folded portion of the holder, with an enlarged first insertion port extending from one end of the first holding groove. A second end portion is arranged to locate at one side of and partially hinder the first insertion port. In the light of the deformability of the holder, the first insertion port can be triggered to become accessible by a small force applied by the user, through which items may be introduced and slide along the first holding groove. The invention is of high durability, versatility and cost-effectiveness accordingly and adapted for conveniently and stably holding a number of keyrings, loops, bead chains and hooks.
