Lid Adjuster With Removable Hinge Pin for Transport Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid adjusters for furniture flaps pose a risk of accidental movement during transport, leading to potential accidents due to unintentional pivoting from the closed to open position, and existing solutions do not adequately address this issue while maintaining simplicity and ease of assembly.
Innovation Solution
A lid adjuster design where the actuating arm is rotatably mounted via a hinge pin that can be detached from the base body, allowing the entire positioning arm to be removed, and a securing element is used to prevent accidental actuation, ensuring safety during transport and easy reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuating arm is permanently fixed to the base body, then the structure is stable and simple, but the risk of accidental actuation increases during transport
Solution Approach 1:
The actuating arm is divided into a removable portion (including the actuating contour) and a remaining portion (including the hinge connection). The hinge pin connects these segments, allowing the actuating arm to be detached from the base body when needed, eliminating the risk of accidental actuation during transport while maintaining a simple assembled structure.
Solution Approach 2:
The actuating contour portion of the actuating arm can be completely removed from the base body by detaching the hinge pin. This extraction eliminates the harmful interaction between the actuator and the actuating contour during transport, while allowing easy reassembly when the furniture flap is installed.
2Reliability
If the hinge pin is made removable, then the risk of accidental actuation is reduced, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The hinge pin is pre-configured with a head portion that can be easily gripped and a threaded design that simplifies insertion and removal. The actuating arm is pre-positioned such that removing the hinge pin automatically disconnects the actuating contour from the actuator, eliminating the need for additional disassembly steps and maintaining ease of operation.
3Productivity
If the actuating contour remains in contact with the actuator, then the lid adjuster functions properly, but the risk of injury increases during transport
Solution Approach 1:
The hinge pin is designed to be removable, allowing the actuating contour to be completely separated from the actuator before transport. This preliminary separation prevents any possible harmful interaction between the actuator and actuating contour during transport, while allowing full functional contact when the furniture flap is installed and the hinge pin is secured.
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
This design effectively reduces the risk of accidents by preventing unintentional actuation of the actuating arm and allows for simple assembly and disassembly, ensuring the actuator does not come into contact with the actuating arm, thereby avoiding injuries during transport and installation.
