Solution Overview

Problem

Conventional fastening systems for panels and walls are complex, time-consuming, and require multiple tools and adjustments, often resulting in inaccuracies and increased costs due to the need for precise hole positioning and alignment, which can lead to unstable or impossible mounting.

Innovation Solution

A fastening system comprising a holding element with a through hole and a rotating element that can be inserted and secured within the holding element, providing radial and axial freedom of movement to compensate for assembly tolerances, allowing for easy correction of drilling errors and alignment without the need for additional tools like shims.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fastening methods with screws and wall plugs are used, then the panel can be securely fastened to the wall, but the assembly process becomes complicated and time-consuming due to the need for precise hole positioning and alignment

Engineering Contradiction:
Improvemounting stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening system is divided into separate functional components: a panel element with integrated fastening features, a wall element with corresponding receptacles, and a fastening element that connects them. This segmentation allows each component to be optimized independently and simplifies the overall assembly process by eliminating the need for precise pre-drilled holes in both the panel and wall.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening element acts as an intermediary component that bridges the panel element and wall element. It provides the connecting function while accommodating misalignments and tolerances, thereby simplifying the assembly process and reducing the need for precise hole positioning in both the panel and wall.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional fastening methods require precise hole positioning in both panel and wall, then secure mounting is achieved, but assembly time increases due to increased control and adjustment efforts

Engineering Contradiction:
Improvemounting stabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The panel element is pre-equipped with integrated fastening features (such as protrusions or integrated anchors) that are prepared in advance during panel manufacturing. This preliminary action eliminates the need for on-site hole drilling and positioning adjustments, significantly reducing assembly time while maintaining mounting stability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fastening system incorporates tolerance compensation mechanisms that allow for parameter variations in hole positioning. The design accepts a range of positioning parameters rather than requiring exact precision, thereby reducing the time needed for control and adjustment efforts during assembly.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If additional aids like shims or spacers are used for alignment, then the panel can be positioned accurately, but the workload increases and the risk of damaging materials increases due to repeated screwing and unscrewing

Engineering Contradiction:
Improvealignment precisionVSAvoidassembly ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The alignment and fastening functions are merged into a single integrated operation. The fastening element is designed to simultaneously achieve both precise alignment and secure fastening in one action, eliminating the need for separate alignment steps using shims or spacers and the subsequent repeated screwing and unscrewing operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fastening element serves as an intermediary that provides built-in alignment features, eliminating the need for separate alignment aids like shims or spacers. This integration simplifies the assembly process by combining alignment and fastening into a single step, reducing workload and minimizing the risk of material damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If conventional fastening systems use multiple components like screws, threaded rods, and wall plugs, then secure mounting is achieved, but the quantity of additional components and assembly steps increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The fastening element is designed as a universal component that performs multiple functions: it provides the connecting function, accommodates misalignments, and ensures secure mounting. This multi-functionality eliminates the need for separate screws, threaded rods, and wall plugs, reducing the total number of components while maintaining mounting stability.

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

Solution Approach 2:

Multiple fastening functions are merged into a single integrated fastening element. Instead of using separate components like screws, threaded rods, and wall plugs, the design combines these functions into one component that achieves secure mounting with fewer parts and simpler assembly.

Inventive Principle:
Principle #5Merging (Combining)
