Solution Overview

Problem

Composite material frame profiles used in solar energy modules have weak lateral strength, making quick plug-in connections with toothed corner connectors difficult due to mechanical clamping methods like interference fit or convex-concave fit.

Innovation Solution

A composite material frame profile with a plug-in cavity containing fiber fabric side walls and bumps or bosses that enhance mechanical strength, allowing for quick and secure connection with toothed corner connectors, where the bumps or bosses are reinforced with resin and designed with tapered holes to prevent cracking during punching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mechanical clamping methods like interference fit or convex-concave fit are used for plug-in connection, then connection can be achieved, but lateral strength is weak and quick plug-in connection cannot be performed

Engineering Contradiction:
Improveplug-in connection speedVSAvoidlateral strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent applies composite materials by embedding fiber fabric (such as glass fiber) within the plastic material of the frame profile, particularly concentrating fibers in the corner connector mounting area. This composite structure significantly enhances the lateral strength of the profile while maintaining the ability to perform quick plug-in connections with toothed corner connectors.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent implements local quality by selectively distributing fiber fabric within specific regions of the profile rather than uniformly throughout. The fiber concentration is increased in the corner connector mounting area where bumps or bosses are located, providing localized strength enhancement exactly where the plug-in connection occurs, without unnecessarily increasing the weight or complexity of the entire profile.

Inventive Principle:
Principle #3Local quality

2Strength

If fiber fabric is added to enhance mechanical strength, then lateral strength and connection strength are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvemechanical strength of corner connector mounting areaVSAvoidmanufacturing process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent merges the fiber fabric reinforcement with the existing plastic extrusion process. The fiber fabric is embedded within the plastic material during the extrusion成型 process, combining two manufacturing steps into one. This integrated approach enhances mechanical strength while avoiding the need for separate reinforcement installation steps, thereby controlling manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes parameter changes by controlling the distribution, orientation, and concentration of fiber fabric within the plastic matrix during extrusion. By adjusting these parameters (fiber orientation angles, fabric layer positioning, resin-to-fiber ratios), the mechanical strength can be optimized for specific load conditions while maintaining a relatively simple manufacturing process.

Inventive Principle:
Principle #35Parameter changes
