Bay Window Assembly with Integrated Structural Brackets

Solution Overview

Problem

The laborious process of constructing bay windows on-site due to the need for on-site assembly and anchoring of pre-fabricated parts, which complicates and prolongs the installation process.

Innovation Solution

A bay window assembly system featuring pre-fabricated structural securing brackets that connect the floor and roof elements, allowing the bay window to be lifted and installed as a unit, eliminating the need for on-site assembly and anchoring, and enabling quick installation by using structural roof and floor bodies that project from the wall to support the elements and transmit forces to the building.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If bay window parts are pre-fabricated but assembled on-site, then manufacturing precision is improved, but installation time and labor increase

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges the securing brackets with the bay window structure itself, making them integral components rather than separate elements. This integration allows the entire bay window assembly to be pre-fabricated as a complete unit, eliminating on-site assembly operations and enabling direct installation of the finished structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The securing brackets are pre-installed and integrated into the bay window structure during manufacturing. This preliminary action of combining structural and securing functions before delivery allows the bay window to be installed as a complete unit, significantly reducing on-site assembly time while maintaining manufacturing precision.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional on-site anchoring is used, then adaptability to different building structures is improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The securing brackets are designed with multi-functionality, serving both as structural support elements and as anchoring mechanisms. This universal design allows the same integrated component to handle multiple functions, reducing the number of separate elements needed and simplifying the overall installation process while maintaining adaptability to different building structures.

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

3Strength

If more structural elements are added for support, then strength and stability are improved, but thermal insulation performance deteriorates due to thermal bridges

Engineering Contradiction:
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent employs composite material construction where the securing brackets are integrated into the bay window structure. This composite approach allows the structural elements to be optimized for both strength and thermal performance, reducing thermal bridges by carefully designing the integration points and using materials or configurations that minimize heat transfer while maintaining structural integrity.

Inventive Principle:
Principle #40Composite materials
