Solution Overview

Problem

Existing modular wall systems face challenges in aligning panels with studs during installation, leading to delays and increased costs, and they often have gaps that compromise hygiene and aesthetics, particularly in medical treatment environments, due to progressive installation methods and protruding ledges.

Innovation Solution

The modular wall system incorporates a gap cover apparatus with brackets and fasteners that interface with modular wall units, allowing for non-progressive installation and eliminating protruding ledges while maintaining structural integrity and hygiene, using a method that includes fastening units to a support structure and positioning gap cover apparatus in gaps to cover them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If progressive installation method is used, then wall panels can be installed sequentially from corner, but installation becomes complicated, expensive, and time-delayed

Engineering Contradiction:
Improveease of installationVSAvoidinstallation speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent inverts the traditional progressive installation approach by enabling non-progressive installation where panels can be installed independently without sequential dependency. The adjustable positioning mechanisms allow panels to be installed in any order rather than requiring corner-to-corner progression, fundamentally reversing the installation sequence logic.

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

Solution Approach 2:

The patent introduces dynamic adjustable positioning mechanisms including adjustable spacers and positioning elements that can adapt during installation. These dynamic components allow installers to accommodate variations in panel dimensions and stud positions, enabling flexibility in installation sequence and method rather than rigid progressive installation.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If wall panels do not align with studs, then re-forming of panels is required, but this causes installation delays and increased costs

Engineering Contradiction:
Improvepanel alignment precisionVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent changes the installation parameters by introducing adjustable positioning elements and spacers that compensate for misalignment between panels and studs. Rather than requiring precise factory alignment, the system allows in-situ adjustment of panel positions through variable spacer thicknesses and adjustable positioning mechanisms.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces intermediary components such as adjustable spacers and positioning elements that mediate between the wall panels and studs. These intermediaries absorb alignment discrepancies and enable installation without requiring precise direct alignment between panels and structural studs.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If gaps occur in wall system, then aesthetics are hindered and hygiene is compromised, but gap cover apparatus is needed

Engineering Contradiction:
Improvehygiene qualityVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The gap cover apparatus serves multiple functions: it seals gaps for hygiene, provides aesthetic coverage, and can incorporate adjustable positioning elements. This multi-functional design eliminates the need for separate gap sealing components and positioning devices, reducing overall system complexity while addressing multiple concerns simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the gap cover function with the positioning and sealing functions into an integrated apparatus. The gap cover apparatus combines aesthetic covering elements with sealing components and can include integrated positioning features, consolidating multiple previously separate functions into a single unified component.

Inventive Principle:
Principle #5Merging (Combining)

4Strength

If protruding ledges are present, then structural integrity may be maintained, but aesthetics are compromised and hygiene is hindered

Engineering Contradiction:
Improvestructural integrityVSAvoidsurface flatness
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

The patent applies local quality by providing adjustable positioning elements and gap cover apparatus at specific locations where protruding ledges occur, rather than requiring uniform modification throughout the entire wall system. This allows maintenance of structural integrity at critical points while achieving flat aesthetic surfaces at visible locations.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent addresses protruding ledges by introducing adjustable spacers and positioning elements that work in the depth dimension behind the panel face. These components compensate for protrusions by providing variable thickness positioning, allowing the front surface to remain flat while accommodating structural variations in the rear dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
