Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric field unit and power unit are integrally combined in the processing apparatus, then the structure is compact, but inconvenience occurs during discharging the cooked food to the outside and vibrations are severe during cooking
Solution Approach 1:
The apparatus is divided into a processing apparatus and a power supply apparatus. The processing apparatus includes a container for holding food materials and a crushing unit with a rotary blade, while the power supply apparatus includes a motor and is detachably connected to the processing apparatus. This segmentation allows the processing apparatus to be easily handled and food to be discharged conveniently, while the power supply apparatus can be separately managed.
Solution Approach 2:
The power unit (motor) is extracted from the processing apparatus and made detachable. The processing apparatus can be separated into an upper container module and a lower power supply module, allowing the processing part to be easily discharged and cleaned without the motor, while the motor remains in the power supply module.
2Volume of moving object
If the electric field unit and power unit are integrally combined in the processing apparatus, then the structure is compact, but forces for crushing during the internal cooking are not transmitted properly and generation of noise is serious
Solution Approach 1:
A power transmitting unit including a gear is introduced as an intermediary between the motor and the rotary blade. The gear transmits and amplifies the rotational force from the motor to the rotary blade, ensuring proper force transmission for crushing food materials. This intermediary mechanism compensates for the distance and connection issues between the detached power unit and processing unit.
3Speed
If universal motors are used for crushing food materials, then the motors can be easily rotated at high speed with constant rotation direction, but the number of no-load revolutions is high, electrical and mechanical noises are large, and life span is short
Solution Approach 1:
The universal motor is replaced with a direct current motor that uses electromagnetic fields instead of mechanical commutators and carbon brushes. This substitution eliminates the mechanical noise and vibration caused by commutator-brush friction, reduces no-load revolutions, and extends motor lifespan while maintaining high-speed rotation capability through electronic control.
4Force
If carbon brushes are used to supply electricity to the commutator, then friction with the commutator is minimized, but they are worn out little by little, which causes generation of carbon powder
Solution Approach 1:
The mechanical commutator and carbon brush system is replaced with a brushless direct current motor design. Electricity is supplied to the motor windings through slip rings or wireless power transmission, eliminating the need for carbon brushes. This substitution prevents carbon brush wear and carbon powder generation entirely while maintaining efficient electromagnetic force generation.
5Power
If the power unit utilizes the rotational force of the driving motor within a limited space, then the motor operates efficiently, but the generation of heat due to the driving of the motor cannot be avoided
Solution Approach 1:
The heat generation issue is extracted and managed separately from the motor operation. The motor is housed in a dedicated power supply module with thermal management features, allowing the motor to operate efficiently in a compact space while heat is dissipated through the module's structure or active cooling systems.
Solution Approach 2:
The heat generated by the motor is converted into a useful function by introducing a steam generation unit. The heat that would otherwise be wasted is utilized to generate steam for cooking food materials, transforming a harmful byproduct into a beneficial cooking resource and improving overall energy efficiency.
6Reliability
If heat and carbon powder generated by the motor fail to discharge to the outside in a timely manner, then there is a possibility that the head and carbon powder may cause frequent failures of the equipment
Solution Approach 1:
The heat and carbon powder discharge function is extracted as a separate system component. A discharge unit with exhaust channels is integrated into the power supply module, actively extracting and venting heat and carbon powder to the external environment, preventing accumulation that would cause equipment failures.
7Device complexity
If the apparatus cannot utilize steam generated during food processing, then the cooking process is simple, but the opportunity for secondary cooking and resource utilization is lost
Solution Approach 1:
The steam generated during food cooking is utilized for a second cooking function. A steam cooking unit is integrated into the processing apparatus, allowing the same steam to cook additional food materials or perform steaming operations, thereby adding multi-functionality to the apparatus and improving resource utilization without significantly increasing complexity.
