Shower Door Fixation Bore for Single-Person Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower door fixation methods require at least two persons to align and secure large shower doors to wall profiles, making the process cumbersome and inefficient.
Innovation Solution
A fixation device with moveable structures within a frame that form a threaded bore, allowing for quick pre-fixation and secure attachment of shower doors to profiles, featuring adjustable diameter and locking mechanisms for single-person operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screwing method is used to secure hinge to wall profile, then reliable fixation is achieved, but at least two persons are required for alignment and tightening
Solution Approach 1:
The fixation device incorporates moveable structures that can dynamically change the diameter of the threaded bore. During insertion, the bore diameter is enlarged to accommodate the bolt, and after positioning, the diameter decreases to engage and secure the bolt, enabling single-person operation while maintaining reliable fixation
Solution Approach 2:
The moveable structures are pre-configured to automatically enlarge the bore diameter upon bolt insertion and subsequently decrease to engage the bolt. This preliminary action eliminates the need for separate alignment and tightening operations by different persons
2Manufacturing precision
If shower door is kept aligned during screw tightening, then proper positioning is achieved, but this requires coordination of at least two persons
Solution Approach 1:
The fixation device performs self-alignment through its moveable structures that automatically adjust the bore diameter in response to bolt insertion. The device maintains alignment precision without requiring external coordination or complex mounting procedures
3Ease of operation
If fixation device with moveable structures is used, then single-person operation is enabled, but device structure becomes more complex
Solution Approach 1:
The fixation device is segmented into a frame and at least two moveable structures that can independently adjust. This segmentation allows each component to perform a specific function (enlarging or decreasing bore diameter) while keeping the overall device structure manageable and enabling single-person operation
