Solution Overview

Problem

Existing drywall support frames for sliding doors face challenges in easy assembly and accurate alignment of cross members, leading to increased effort and risk of incorrect screw hole placement.

Innovation Solution

A drywall support frame design featuring a connecting element that clips onto vertical profiles, allowing for temporary alignment and marking of screw holes before a permanent connection is established through screwing, which can be made from plastic, sheet metal, or die-cast materials to accommodate tolerances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cross profiles are held freely during alignment, then the assembly process allows flexibility in positioning, but the assembly effort increases and the risk of incorrect screw hole placement rises

Engineering Contradiction:

Improvealignment processVSAvoidassembly time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

A marking device is introduced as an intermediary tool between the cross profile and the vertical profile. This device includes a base that attaches to the cross profile and a marking element that transfers position information to the vertical profile, facilitating accurate alignment without requiring manual holding and marking procedures

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The marking device enables preliminary marking of screw hole positions before final assembly. By pre-marking the correct positions on the vertical profile during alignment, the subsequent drilling and screwing operations can proceed quickly and accurately without repositioning or correction

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If screw holes are pre-drilled in cross profiles, then assembly is simplified, but positioning accuracy and alignment precision deteriorate

Engineering Contradiction:

Improveassembly processVSAvoidscrew hole placement accuracy

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The marking device serves as an intermediary that transfers precise position information from the cross profile to the vertical profile. This ensures that screw holes are drilled at the correct positions after alignment is achieved, maintaining manufacturing precision while simplifying the overall assembly process

Inventive Principle:

Principle #24Intermediary (Mediator)

3Difficulty of detecting and measuring

If cross profiles are kept clear during alignment, then visibility and access are improved, but the risk of incorrect hole drilling increases

Engineering Contradiction:

Improvealignment visibilityVSAvoidscrew hole positioning reliability

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The marking device provides a reliable mechanism for transferring position information that does not depend on visual inspection alone. By physically marking the correct positions on the vertical profile, it ensures accurate screw hole placement even when the cross profile is kept clear for visibility and access during alignment

Inventive Principle:

Principle #24Intermediary (Mediator)
