Solution Overview

Problem

Existing hinges are difficult to assemble and disassemble due to securely fastened plates and challenging link insertion/removal, leading to time-consuming and frustrating processes for attaching and detaching hinged objects.

Innovation Solution

A hinge design featuring a first flange and a second flange with a pin, where the pin is manually insertable and retractable through sleeve segments, allowing for easier assembly and disassembly, with the pin being prevented from retracting by a tab, enabling objects to be easily attached and detached.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plates are securely fastened to objects using screws, nails, or bolts, then the hinge provides strong and reliable connection, but the assembly and disassembly process becomes time-consuming and difficult

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The hinge is divided into separate components: a first plate, a second plate, and a link. The link is inserted into slots in both plates rather than being permanently fastened, allowing the hinge to be segmented into removable parts for quick assembly and disassembly while maintaining connection strength during use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The link acts as an intermediary component between the two plates. Instead of directly fastening plates to objects with difficult-to-remove fasteners, the link provides a removable intermediary connection that can be easily inserted and removed from the plate slots, reducing assembly time while maintaining reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the link is securely inserted into both plates, then the hinge provides stable connection, but the link becomes difficult to insert and remove

Engineering Contradiction:
Improvehinge stabilityVSAvoidlink insertion ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection interface is segmented into slots in the plates that receive the link. This segmentation allows the link to be inserted into defined pathways rather than requiring complex alignment or forceful insertion, making the operation easier while maintaining stable connection when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The geometry of the link and slots is designed with specific parameters that facilitate easy insertion. The link has a shape that matches the slot dimensions, allowing it to slide in smoothly. When inserted, the geometric parameters create a stable fit that maintains hinge stability during operation.

Inventive Principle:
Principle #35Parameter changes

AI summary

A hinge (100) including a first flange (102) having a first sleeve segment (218) and a portioned sleeve segment (222) is disclosed. The hinge (100) also includes a second flange (104) having a second sleeve segment (314). The second flange (104) is configured to mate with the first flange (102) such that the first sleeve segment (218), the second sleeve segment (314), and the portioned sleeve segment (222) are substantially aligned. A pin (106) is configured to be removably inserted into the first sleeve segment (218) and the second sleeve segment (314). Also disclosed are a method for assembling a hinge (100) and a container assembly including a hinge (100).
