Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional microwave oven housing structure is used, then the oven is compact and portable, but it cannot withstand heavy vibrations, accidental blows, and severe stresses in rugged environments
Solution Approach 1:
The patent applies beforehand cushioning by incorporating shock-absorbing materials and protective framing elements into the housing structure before the oven is subjected to shocks or vibrations. These elements are pre-positioned to absorb and dissipate impact energy, protecting sensitive internal components from damage during transport or use in rugged environments.
Solution Approach 2:
The patent uses composite materials by combining conventional housing materials with specialized shock-absorbing materials. The housing incorporates layers or sections of materials with different mechanical properties, such as foam insulation combined with rigid outer shells and flexible sealing elements, creating a composite structure that provides both structural integrity and shock absorption capabilities.
2Strength
If the microwave oven is designed for portability, then it can be easily transported, but it lacks protection against accidental blows from tools and falling materials
Solution Approach 1:
The patent employs flexible shells and thin films by incorporating flexible protective coverings and sealing membranes into the housing. These flexible elements can deform under impact to absorb shock energy while maintaining the overall structural integrity of the housing, providing protection against accidental blows without significantly increasing the weight of the portable oven.
3Reliability
If the microwave oven housing is made more robust to withstand rugged environments, then shock resistance improves, but the oven becomes heavier and less portable
Solution Approach 1:
The patent applies segmentation by dividing the housing into multiple modular sections or compartments, each designed to perform specific protective functions. This segmentation allows the housing to be constructed with lighter materials in non-critical areas while concentrating protective elements only where needed, such as around sensitive components or impact-prone surfaces, thereby reducing overall weight while maintaining reliability in rugged environments.
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 effectively minimizes damage from accidental shocks and vibrations while ensuring continuous operation in rugged environments by using shock-absorbing materials and a rechargeable battery for power, enhancing the oven's durability and usability.
Implementation Method 1
Each connector is formed from a shock absorbing material. A plurality of support members are provided, with each support member being mounted to, and joining, a respective adjacent pair of connectors. The support members form the protective frame about the microwave oven and provide a shock-absorbing shield for the microwave oven housing.
