Hinge with Dual Flexible Joints for 180-Degree Connector Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with hinges that rotate 90 degrees suffer from poor workability due to interference between components, leading to potential breakage when attempting to rotate beyond this angle.
Innovation Solution
A housing and connector design featuring a hinge with a first flexible joint between the housing body and connection, and a second flexible joint between the assembly and connection, allowing for 180 degrees of rotation without breakage by distributing the bending load across both joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the hinge rotates 90 degrees, then the connector structure is compact, but the retainer and other components interfere with each other resulting in poor workability
Solution Approach 1:
The hinge is divided into two separate joints: a first joint connecting the housing body to the connection, and a second joint connecting the assembly to the connection. This segmentation allows each joint to rotate independently (90 degrees each), enabling the assembly to achieve 180 degrees total rotation while avoiding component interference that would occur with a single 90-degree rotation
2Ease of operation
If the retainer rotates more than 90 degrees to avoid interference, then workability improves, but the hinge may break
Solution Approach 1:
By dividing the hinge into two joints that each rotate 90 degrees, the total rotation angle is distributed across both joints. This prevents any single joint from exceeding its safe rotation limit while achieving the required 180 degrees total rotation, thereby improving workability without increasing hinge breakage risk
Solution Approach 2:
The two-joint hinge structure dynamically adapts the rotation path by allowing sequential rotation at each joint. This dynamic configuration enables the assembly to rotate 180 degrees in a controlled manner, avoiding the need for any single joint to rotate beyond 90 degrees and thus preventing hinge breakage
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 design enhances workability by allowing smooth assembly and reduced hinge breakage through controlled bending angles and flexible joint configurations, ensuring the connector can rotate 180 degrees without interference or damage.
Implementation Method 1
a hinge with the assembly mounted thereon, and including (i) a connection arranged between the housing body and the assembly, on which an abutment is formed, (ii) a first joint disposed between the housing body and the connection, and having flexibility, and (iii) a second joint disposed between the assembly and the connection, and having flexibility

AI summary
A housing includes: a housing body on which a portion for abutment is formed; an assembly that is detachably assembled to the housing body; and a hinge with which the assembly is mounted on the housing body. The hinge includes (i) a connection that is arranged between the housing body and the assembly, and on which an abutment is formed, (ii) a first joint that is disposed between the housing body and the connection, and has flexibility, and (iii) a second joint that is disposed between the assembly and the connection, and has flexibility. The abutment formed on the connection is allowed to abut on the portion for abutment of the housing body by bending the first joint, and the assembly is assembled to the housing body by bending the second joint in a state in which the first joint is bent.
