Solution Overview

Problem

The existing litter bin production process is complex, leading to low production efficiency due to the need for screw-mounted partition plates.

Innovation Solution

The litter bin features an integral partition plate and sifter, which are integrally molded with the bin body, simplifying the assembly process and reducing production steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screw-mounted partition plate is used in the litter bin, then the partition plate can be securely assembled, but the production procedure becomes complex and production efficiency decreases

Engineering Contradiction:
Improvepartition plate assembly reliabilityVSAvoidlitter bin production efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The partition plate is integrally molded with the bin body, merging two separate components (partition plate and bin body) into a single integrated structure. This eliminates the need for separate assembly steps using screws, thereby simplifying the production procedure and improving production efficiency while maintaining structural reliability

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a screw-mounted partition plate is used in the litter bin, then the partition plate can be securely fixed, but the production procedure complexity increases

Engineering Contradiction:
Improvepartition plate fixation stabilityVSAvoidproduction procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By integrating the partition plate with the bin body through integral molding, the invention reduces the number of discrete parts and assembly operations. This merger eliminates complex screw-fastening procedures while maintaining secure fixation, thereby reducing production procedure complexity

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate partition plate and bin body components are used, then assembly flexibility is maintained, but gaps between components cause litter retention

Engineering Contradiction:
Improveassembly flexibilityVSAvoidlitter retention in gaps
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The integral molding of the partition plate with the bin body creates a seamless, gap-free structure. This merger eliminates the harmful effect of litter retention in gaps between components while maintaining the necessary structural functionality and adaptability of the litter bin

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present disclosure discloses a litter bin and a pet toilet. The litter bin includes a bin body, an integral partition plate and a sifter, which are arranged in the bin body. The integral partition plate and an inner wall of the bin body form a receiving slot, and the integral partition plate is integrally molded with the bin body; a second opening is formed in one side, away from a notch of the receiving slot, of the bin body. When the bin body rotates, pet litter and waste are sifted through the sifter; and when the bin body continues to rotate, the waste is rotated to the second opening along the integral partition plate.
