Solution Overview

Problem

Existing fastening systems for profiles are often difficult to mount, do not provide strong attachment, and are complex to manufacture, lacking ease of assembly and stability.

Innovation Solution

A fastening system comprising a profile with clamping pieces and fastening means, where the fastening piece engages with projections into edge grooves and clamping pieces, using an elastic element to facilitate assembly and introduce forces that prevent the profile from spreading or compressing, enhancing stability and load-bearing capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional fastening systems use screws and clamping pieces with complex assembly steps, then the fastening strength is improved, but the ease of assembly deteriorates

Engineering Contradiction:
Improvefastening strengthVSAvoidease of assembly
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The fastening system is divided into distinct functional components: a profile with groove, a fastening piece with projection, and clamping pieces. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process while maintaining strong fastening through the interlocking projection-groove mechanism combined with clamping action.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening piece with projection automatically engages with the groove in the profile, creating self-alignment and self-positioning during assembly. The clamping pieces then simply need to be inserted and tightened, eliminating the need for complex alignment procedures or multiple fastening steps required by traditional systems.

Inventive Principle:
Principle #25Self-service

2Reliability

If fastening systems use multiple clamping pieces and fastening means, then the reliability of fastening is improved, but the device complexity increases

Engineering Contradiction:
Improvefastening reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The profile integrates multiple functions into a single component: it provides the structural support, contains the groove for fastening engagement, and offers contact surfaces for the clamping pieces. This merging reduces the number of separate parts needed while maintaining reliable fastening through the combined mechanical engagement of projection-groove and clamping action.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamping pieces serve multiple functions simultaneously: they apply clamping force to secure the fastening piece, distribute loads across the contact surfaces, and prevent both spreading and compression of the profile through their positioning against the contact surfaces. This multi-functionality reduces the need for additional specialized components.

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

3Strength

If fastening systems provide strong attachment forces, then the load-bearing capacity is improved, but the profile may spread or compress under load

Engineering Contradiction:
Improveload-bearing capacityVSAvoidprofile stability
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The clamping pieces are positioned to counteract both spreading and compression forces on the profile. When load is applied, the clamping pieces exert opposing forces against the contact surfaces, preventing the profile from deforming. This counterbalancing action maintains profile stability while allowing strong attachment forces to be transmitted through the fastening system.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
