Solution Overview

Problem

Conventional solar battery modules face issues with misalignment between rafter positions and joint portions, leading to poor fixing strength and increased costs due to complex machining requirements for different shaped frame bodies.

Innovation Solution

A slidable fixing member that restricts upward, downward, and outward movement of solar battery modules, allowing for secure alignment with rafters and reducing the number of frame body parts, featuring a pedestal, to-be connected portion, and plate-like structure for secure mounting and ventilation, with engaging mechanisms for symmetrical frame body connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If joint portions are integrally created with frame bodies for direct mounting on roofboards, then mounting simplicity is improved, but fixing strength deteriorates when rafter positions and joint portions are misaligned

Engineering Contradiction:
Improvemounting simplicityVSAvoidfixing strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The fixing member is separated from the frame body into an independent component. The frame body and fixing member are distinct parts that can be assembled together, allowing the fixing member to be positioned independently to align with rafters while the frame body maintains its standard design for solar panel mounting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing member acts as an intermediary component between the frame body and the rafter. It provides an intermediate mounting interface that can accommodate misalignment between the frame body's joint portions and the rafter positions, transferring loads effectively while allowing positional adjustment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If different shaped frame bodies are used for ridge-side and eaves-side modules to achieve proper connection, then connection reliability is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidframe body shape variety
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fixing member is designed as a universal component that can be used for both ridge-side and eaves-side module connections. The same fixing member design works for different frame body orientations, eliminating the need for separate ridge-side and eaves-side specific fixing components.

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

Solution Approach 2:

While the fixing member itself is symmetric and universal, the installation orientation adapts to asymmetric roof positions. The fixing member's symmetric design allows it to function correctly whether installed on the ridge side or eaves side, simplifying the system while maintaining connection reliability for asymmetric module arrangements.

Inventive Principle:
Principle #4Asymmetry

3Reliability

If different shaped frame bodies with complicated machining are used to achieve proper connection, then connection reliability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By separating the fixing function into an independent fixing member, the standardization benefit is realized. The fixing member can be manufactured using simple, standardized processes while the frame body maintains its standard solar panel mounting design, reducing overall manufacturing complexity and cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing member design allows for parameter adjustment in positioning without changing the fundamental design of frame bodies. This enables reliable connection through positional adaptation rather than through complicated machining of different frame body shapes, reducing manufacturing costs.

Inventive Principle:
Principle #35Parameter changes

AI summary

A fixing member of solar battery modules for fixing edges of module glass to a roofboard by solar battery modules supporting a first frame body, including: a to-be connected portion to restrict the first frame body from moving upward; a pedestal to restrict the first frame body from moving downward; a portion connecting the pedestal and to-be connected portion to restrict solar battery modules from moving in a direction perpendicular to a longitudinal direction of the first frame body and outwardly along a surface of solar battery modules; and a plate-like portion extending outward farther than one side of the pedestal, the fixing member being fixed to the roofboard through the plate-like portion, supported on both sides of the portion connecting the pedestal and to-be connected portion such that upper surfaces of adjacent solar battery modules are substantially flush with each other, and slidable along the first frame body.
