Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garage doors face challenges in providing adequate thermal insulation and durability, with solid wood doors being expensive and hollow wood structures being prone to denting and requiring regular maintenance.
Innovation Solution
A garage door design featuring a base structure with a cementitious layer on its exterior face, which includes a combination of insulative and strength members, such as Styrofoam and aluminum, providing thermal insulation and dent resistance while being lightweight and low-maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If hollow wood structures are used for garage doors, then weight is reduced and thermal insulation is improved, but dent resistance deteriorates
Solution Approach 1:
The patent applies composite materials by combining a wood base structure with a cementitious coating layer. The wood provides lightweight properties and thermal insulation, while the cementitious layer adds dent resistance and durability. This composite structure resolves the contradiction by integrating materials with complementary properties.
2Ease of manufacture
If hollow wood structures with thin sheets are used, then manufacturing cost is reduced, but durability and weather resistance deteriorate
Solution Approach 1:
The cementitious coating layer is applied over the hollow wood structure to create a composite material system. This maintains the cost-effectiveness and insulation properties of the hollow structure while adding the durability and weather resistance of cementitious materials, resolving the contradiction between manufacturing ease and reliability.
3Weight of moving object
If thin wood sheets are used in hollow structures, then weight is reduced, but maintenance requirements increase
Solution Approach 1:
The cementitious coating layer serves as a protective shell that resists weather damage, denting, and deterioration. This self-protecting feature reduces the need for regular maintenance such as repainting, allowing the lightweight hollow structure to maintain its weight advantage while eliminating frequent maintenance requirements.
4Strength
If solid wood panels are used, then strength and durability are improved, but manufacturing cost increases
Solution Approach 1:
The patent creates a composite structure where a hollow wood framework provides the basic strength and structural integrity at lower cost, while a cementitious coating layer adds enhanced durability and weather resistance. This composite approach achieves strength and durability comparable to or exceeding solid wood while reducing manufacturing cost through material optimization.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances thermal insulation, reduces the weight of the garage door, making it easier to operate, and provides durable dent resistance, eliminating the need for frequent repainting due to its weather-resistant cementitious exterior.
Implementation Method 1
Some have an insulative material between the interior and exterior sheets of wood. These structures are typically lighter and less expensive than their solid wood counterparts, and may offer relatively greater thermal insulation against heat loss.
Implementation Method 2
A garage door design featuring a base structure with a cementitious layer on its exterior face
Implementation Method 3
A garage door design featuring a base structure with a cementitious layer on its exterior face, which includes a combination of insulative and strength members, such as Styrofoam and aluminum, providing thermal insulation and dent resistance
