Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household food preparation appliances lack effective safety measures and simplicity in design, making them potentially hazardous and complex to use.
Innovation Solution
A design featuring a base with a laterally arranged electric motorization connector, an upper motorized box with side pins, and an intermediate cover that allows for secure locking and electrical supply, enabling safe operation and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric motorization connector is arranged vertically in the upright, then the structure is simple, but the upper motorized box cannot be securely locked and electrical supply is not safe
Solution Approach 1:
The electric motorization connector is moved from a vertical arrangement to a lateral arrangement in the upright, changing the spatial dimension of connection. This allows the upper motorized box to be securely locked through rotational engagement while ensuring safe electrical supply only when properly positioned.
Solution Approach 2:
The connection mechanism transitions from a static vertical connector to a dynamic rotational locking system. The upper motorized box can be rotated to engage with the lateral connector, providing both mechanical locking and electrical connection through a single rotational motion.
2Reliability
If multiple locking mechanisms are added to secure the upper motorized box, then safety is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism merges two functions into one: mechanical retention through rotation around the axis of rotation and electrical connection through engagement of the lateral connector. This single rotational action provides both locking and electrical supply, avoiding the need for separate locking mechanisms.
3Ease of operation
If the upper motorized box is easily removable from the working container, then ease of operation is improved, but safety is compromised
Solution Approach 1:
The connection system uses a dynamic rotational locking mechanism that requires a specific rotational motion to engage or disengage. This prevents accidental removal while maintaining ease of operation through a simple rotational action rather than complex locking procedures.
4Ease of operation
If electrical supply is always available, then ease of operation is improved, but safety is compromised due to improper assembly
Solution Approach 1:
The electrical supply is dynamically controlled through the rotational locking mechanism. Electrical contact is established only when the upper motorized box is properly rotated into the locked position, ensuring that power is supplied only when the device is correctly assembled and safe to operate.
