Solution Overview

Problem

Existing electric pepper grinders face issues with inconvenient operation due to detachable storage bins and uneven particle flow, leading to unstable design and inconsistent grinding results.

Innovation Solution

An electric pepper grinder design featuring a storage bin integrated into the shell with a control switch to prevent accidental startup and ensure even particle flow, where the bin cover can be opened for loading without detaching the bin, and a separation wall between the grinding and power mechanisms for improved compactness and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the storage bin is made detachable for easy loading, then the ease of operation is improved, but the device complexity and stability deteriorate due to repeated removal and loosening

Engineering Contradiction:
Improveease of loadingVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage bin is segmented into two parts: a detachable bin body and a fixed bin cover. The bin cover remains attached to the shell while the bin body can be removed for loading. This segmentation allows easy access to the storage compartment without requiring removal of the entire storage bin assembly, thus improving ease of operation while maintaining structural integrity and reducing device complexity.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If the gravity switch is used to control startup, then the automation is improved, but the reliability deteriorates due to accidental startup when switched off inadvertently

Engineering Contradiction:
ImproveautomationVSAvoidreliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

A control switch is introduced as an intermediary component between the gravity switch and the motor. The control switch acts as a manual override that must be deliberately activated to start the motor, even when the gravity switch detects the upright position. This intermediary mechanism prevents accidental startup while preserving the automated gravity-based control functionality, thus improving reliability without sacrificing automation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If the storage bin is provided on the side wall, then the ease of manufacture is improved, but the stability and grinding evenness deteriorate

Engineering Contradiction:
Improveease of manufactureVSAvoidstability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The storage bin is repositioned from a side-wall attachment to a top-mounted configuration on the shell. This dimensional change places the storage bin in a more stable position that contributes to the overall structural stability of the grinder. Additionally, this positioning allows pepper particles to flow more evenly into the grinding mechanism from above, improving grinding evenness while maintaining ease of manufacture through simple top-mounting.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An electric pepper grinder, wherein, on the one hand, a control switch is provided to avoid starting the grinder by mistake when the gravity switch is turned off inadvertently; on the other hand, the storage bin is formed on the shell non-detachably, and it is just necessary to open the bin cover during loading; further, the storage bin is located in the three-segment structure between the grinding and power mechanisms, realizing evener loading.
