Solution Overview

Problem

The existing bracket systems for roof equipment, such as snow racks and holding profiles, are laborious and costly to mount due to mismatched hole spacings and require specialized fittings, making them inefficient and economically unadvantageous.

Innovation Solution

A bracket design featuring slot-shaped receiving holes that closely match the shape of holding profiles, allowing for easy insertion and secure fastening with simple fastening means like angle-irons and metal plate screws, along with widened hole portions for versatility and deformation capabilities to handle loads, enabling secure anchoring of life lines and roof bridges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional brackets with standard holes are used for fastening holding profiles, then the bracket structure is simple, but the mounting process becomes laborious and requires accurate fitting work due to mismatched hole spacings

Engineering Contradiction:
Improvebracket structure simplicityVSAvoidmounting ease
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The receiving hole is designed with non-uniform geometry - a slot-shaped hole portion that widens at specific locations to match the holding profile shape. This local variation in hole geometry enables accurate alignment and secure fitting without requiring complex bracket structures or multiple brackets.

Inventive Principle:
Principle #3Local quality

2Reliability

If special fittings are used to adapt holding profiles to brackets, then the holding profile can be securely fastened, but the device complexity and cost increase

Engineering Contradiction:
Improvefastening securityVSAvoidfittings and fastening means
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The receiving hole integrates multiple functions into a single structural element. The slot-shaped hole portion provides both alignment guidance and secure retention, while the widened hole portions accommodate fastening operations. This eliminates the need for separate special fittings and reduces the overall fastening system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket design with its versatile receiving hole can accommodate different types of holding profiles and fastening methods. The same bracket structure works for various profile shapes and sizes, making the fastening system universal and eliminating the need for profile-specific special fittings.

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

3Strength

If multiple brackets are positioned after one another to secure the holding profile, then the holding profile can be firmly anchored, but the mounting process becomes more difficult and time-consuming

Engineering Contradiction:
Improveanchoring firmnessVSAvoidmounting speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The receiving hole geometry is optimized to provide maximum anchoring strength through its slot-shaped design that closely connects to the holding profile shape. This single-hole design with optimized parameters achieves the same or better anchoring firmness as multiple brackets would provide, while significantly reducing mounting time and complexity.

Inventive Principle:
Principle #35Parameter changes

4Manufacturing precision

If the receiving hole is designed to closely match the holding profile shape, then unnecessary play is avoided, but the insertion through multiple brackets becomes more difficult

Engineering Contradiction:
Improvefit accuracyVSAvoidinsertion ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The receiving hole is segmented into distinct functional portions: a slot-shaped hole portion for alignment and play reduction, and widened hole portions for insertion and fastening. This segmentation allows each portion to optimize its specific function while working together to achieve both precise fit and easy insertion.

Inventive Principle:
Principle #1Segmentation
