Solution Overview

Problem

Conventional shower door installation processes are inconvenient, time-consuming, and can damage surfaces due to drilling, especially on materials like aluminum.

Innovation Solution

A shower door assembly with a stationary frame, movable frame, upper and lower frames, and an adjusting assembly that includes a fixing block and rotating blocks, allowing for installation without drilling, using a fixing block with a passage and adjusting shaft for secure attachment without surface damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drilling and screw fixing are used to install shower doors, then the frames can be securely fixed to the wall surface, but the installation process becomes time-consuming and may damage the frame surfaces

Engineering Contradiction:
Improvesecure fixationVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing blocks are pre-installed on the wall surface before the shower door frames are assembled. This preliminary action eliminates the need for drilling and screw fixing during the actual door installation, significantly reducing installation time while maintaining secure fixation through the mechanical interlocking design of the fixing blocks and grooves

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fixing blocks serve as intermediary components between the wall surface and the shower door frames. These blocks provide a pre-prepared mounting interface that eliminates direct drilling into the frames, thus reducing installation time while ensuring reliable fixation through the groove-and-protrusion mechanical connection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If drilling is used to fix shower door frames to the wall, then secure attachment is achieved, but the frame surfaces may be damaged or scarred

Engineering Contradiction:
Improveattachment securityVSAvoidsurface damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fixing blocks act as intermediary mounting components that interface with the wall surface independently of the shower door frames. This design eliminates direct drilling into the frame surfaces, preventing damage and scarring while maintaining secure attachment through the mechanical groove-and-protrusion connection between the fixing blocks and frame grooves

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting function is segmented from the frame structure itself. Instead of drilling directly into the frames, the fixing blocks are separate components that provide the mounting interface. This segmentation protects the frame surfaces from drilling damage while ensuring reliable attachment through the dedicated fixing block structure

Inventive Principle:
Principle #1Segmentation

3Reliability

If conventional drilling and screw fixing methods are used, then the shower doors can be installed, but the installation process becomes inconvenient and complex

Engineering Contradiction:
Improveinstallation completenessVSAvoidinstallation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fixing blocks are pre-installed on the wall surface with grooves already formed, and the frame grooves are pre-cut during manufacturing. This preliminary preparation simplifies the final assembly process to a simple insertion and rotation operation, making installation convenient while ensuring complete and reliable installation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The rotating block incorporates a rotating handle that transitions the fixing mechanism from a static insertion to a dynamic locking action. The rotating motion engages the engaging elements with the groove walls, providing an intuitive and convenient operation that ensures complete installation while simplifying the overall process

Inventive Principle:
Principle #15Dynamics
