Solution Overview

Problem

Conventional in-wall frames for retractable sliding doors and drywall dividing walls face challenges in securely fastening plasterboard panels due to the difficulty in perforating metallic crossmembers, which can lead to bending or breaking of the panels, and the risk of screws protruding excessively, causing damage.

Innovation Solution

A method of machining metallic lamina to create uniformly distributed holes in profiled elements, with specific diameter and center distance proportions, to facilitate easy screwing without excessive pressure, ensuring stable and quick fastening of plasterboard panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional affixing systems with screws are used to fasten plasterboard panels to metallic crossmembers, then the panels can be secured to the structure, but the metallic crossmembers have a smooth perforation base that causes excessive pressure and bending during screw insertion

Engineering Contradiction:

Improvefastening strengthVSAvoidease of perforation

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

Holes are pre-formed in the metallic crossmembers at predetermined locations before the plasterboard panels are installed. This preliminary action eliminates the need for technicians to exert excessive pressure during screw insertion, as the holes are already created with appropriate dimensions and positioning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The conventional mechanical process of forcing screws through smooth metal surfaces is replaced by a pre-perforation system. The holes are created using punching or drawing operations that substitute the high-pressure screw insertion process with a controlled hole-forming operation that requires minimal force during final assembly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If excessive pressure is exerted during screw insertion to perforate the metal plate, then the screws can be inserted, but the profiled element bends and the plasterboard panels may break

Engineering Contradiction:

Improveease of screw insertionVSAvoidstructural integrity

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The pre-formed holes act as intermediaries that facilitate the connection between screws and the metallic crossmembers. These holes provide a controlled pathway that reduces the force required for screw insertion while maintaining the structural integrity of both the metal profile and the plasterboard panels.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If the plasterboard panel layer of plaster is compressed between cellulose layers, then the panel achieves compactness and insulation, but the paper covering breaks easily and the plaster crumbles at fastening points

Engineering Contradiction:

Improvepanel compactnessVSAvoidvulnerability at fastening points

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The pre-formed holes in the metallic crossmembers serve as intermediaries that properly distribute the fastening forces. By positioning screws through these pre-created holes, the stress is evenly distributed across the plasterboard panel, preventing the paper covering from breaking and the plaster from crumbling at the fastening points.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The dimensions and positioning of the holes are carefully controlled to optimize the fastening process. The hole diameter and location are parameters that are precisely defined to ensure that screw insertion occurs at optimal points, distributing loads appropriately and protecting the vulnerable paper-plaster interface.

Inventive Principle:

Principle #35Parameter changes

4Ease of operation

If reduced thickness profiled elements are used to facilitate perforation, then easier screw insertion is achieved, but the structural rigidity of the profiled element is weakened
