Door Hinge Installation Device with Intermediary Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching door hinge parts to a door leaf are limited in their ability to handle a wide variety of hinge configurations, particularly when multiple bolts are involved, requiring precise alignment and coaxial positioning for efficient screwing.
Innovation Solution
A device with a pliers-like gripper and a longitudinally displaceable hollow spindle for rotating and aligning bolts, combined with a circular magazine for pre-sorting and positioning hinge parts, and a rotary device for precise alignment and attachment, allowing for the use of exchangeable bits and accommodating bolts of different lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pliers-like gripper is used to grasp the shank and rotate the hinge part for screwing in the bolt, then the attachment process is simplified, but precise alignment and coaxial positioning become difficult when multiple bolts are involved
Solution Approach 1:
The patent introduces a positioning device with a positioning element that acts as an intermediary between the gripper and the hinge part. This positioning element ensures precise alignment and coaxial positioning of multiple bolts during the screwing process, while the gripper continues to provide easy grasping and rotation functionality. The positioning device mediates between the simple grasping action and the precise alignment requirement.
2Adaptability or versatility
If the device is designed to handle a wide variety of hinge configurations with multiple bolts, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent designs the positioning device with a universal positioning element that can accommodate multiple bolt configurations and hinge types. The positioning element is designed to work with various hinge part geometries, allowing a single device structure to handle diverse hinge configurations without requiring multiple specialized tools, thus maintaining versatility while controlling complexity.
3Ease of operation
If the hollow spindle is designed to be longitudinally displaceable for inserting bolts into door leaf holes, then the screwing process is facilitated, but precise coaxial alignment between the shaft and hollow spindle becomes critical
Solution Approach 1:
The positioning element serves as an intermediary that ensures coaxial alignment between the shaft and the longitudinally displaceable hollow spindle. During the screwing operation, the positioning element maintains the precise coaxial relationship while allowing the hollow spindle to move longitudinally for bolt insertion, thus facilitating the screwing process without compromising alignment precision.
