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 hole-free installation using a fixing block and rotating handle mechanism to secure the frames without drilling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drilling holes and using screws to fix the stationary frame and movable frame to the wall, then the installation is secure and reliable, but the installation process becomes time-consuming and may damage the frame surfaces

Engineering Contradiction:
Improveinstallation securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a fixing block as an intermediary component that receives the adjusting shaft and enables the movable frame to be adjusted and fixed relative to the stationary frame without direct drilling into the frames themselves. The fixing block acts as a mediator that facilitates secure connection while avoiding damage to the frame surfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adjusting assembly enables the shower door system to be installed and adjusted without requiring external drilling equipment or complex fastening operations. The rotating blocks and adjusting shafts allow the installation personnel to complete the task using only the components provided in the system, making the installation process self-sufficient and eliminating the need for additional tools that would consume time.

Inventive Principle:
Principle #25Self-service

2Reliability

If drilling holes to install the shower door frames, then the frames can be securely fixed to the wall, but the frame surfaces may be damaged or scarred

Engineering Contradiction:
Improvefixing reliabilityVSAvoidsurface damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fixing block serves as an intermediary that receives the adjusting shaft and enables secure fixing without drilling into the frame surfaces. This mediator component protects the aluminum or alloy frame surfaces from drilling damage while still providing reliable fixation to the wall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of drilling holes in the frames and then inserting screws, the patent inverts the approach by having the adjusting shaft with engaging elements engage with the fixing block first, and then the entire assembly is secured to the wall. This reversal of the installation sequence eliminates the need to drill through the frame surfaces themselves.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If using a complex drilling and screw-fixing process, then the installation is secure, but the installation convenience is reduced

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

Solution Approach 1:

The adjusting assembly is designed to be self-installing, where the rotating blocks can be manually rotated to adjust and fix the movable frame position without requiring external drilling equipment. The engaging elements on the adjusting shaft automatically engage with the fixing block, providing secure fixation through simple manual operation rather than complex drilling and screwing processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The fixing block acts as a mediator that simplifies the installation process by providing a ready-made receiving structure for the adjusting shaft. This intermediary component eliminates the need for on-site drilling and screw fixation, allowing the installation to be completed by simply inserting and rotating the adjusting assembly into place.

Inventive Principle:
Principle #24Intermediary (Mediator)
