Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for handling pet excrement during walks are inconvenient, unsanitary, and pose a risk of disease transmission due to direct contact with the excrement.
Innovation Solution
A foldable portable excrement pick-up device comprising an upper and lower housing forming a clip shape via a rotary shaft and spring, with a flexible storage bin and garbage bag system that allows for safe, hands-free collection and containment of pet waste, preventing leakage and exposure to pathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual paper picking method is used, then the device complexity is low, but the ease of operation is poor and sanitation is compromised due to direct contact with excrement
Solution Approach 1:
The device is divided into multiple functional components: upper housing with picking mechanism, lower housing with storage bin, rotary shaft for rotation, spring for elastic force, and garbage bag system. Each component performs a specific function, allowing complex operations to be broken down into simple automated actions
Solution Approach 2:
A garbage bag is introduced as an intermediary between the picking mechanism and the excrement. The bag contacts the excrement instead of human hands, providing sanitation while the mechanical system handles the collection and storage processes
2Volume of moving object
If a rigid storage structure is used, then the reliability is high, but the volume is large and portability is reduced
Solution Approach 1:
The lower housing contains a flexible storage bin that can dynamically change its volume. When not in use, the bin folds into a compact thin-film form reducing overall device volume. When in use, it expands to provide adequate storage capacity while maintaining structural integrity through the flexible material properties
Solution Approach 2:
The storage bin is constructed from flexible material that can be folded into a thin-film organ shape for compact storage. The flexibility allows the bin to adapt its volume while the frame structure provides necessary support, achieving both small packaged size and reliable storage function
3Adaptability or versatility
If the device is made foldable and portable, then the ease of operation and portability are improved, but the device complexity increases due to additional hinging and spring mechanisms
Solution Approach 1:
The rotary shaft and spring are integrated into the hinging mechanism between upper and lower housings. The spring is positioned between the handles and works together with the rotary shaft to provide both the folding capability and the elastic closing force, combining multiple functions into a unified mechanism rather than separate components
Solution Approach 2:
The hinging mechanism serves multiple functions: it allows the device to fold for portability, provides elastic force for automatic closing, and enables the clip-shaped configuration for secure excrement containment. This multi-functional design reduces the need for additional separate mechanisms
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 device ensures convenient, sanitary, and safe handling of pet excrement, reducing the risk of disease transmission and environmental contamination while being easy to use and store.
Implementation Method 1
the spring may be arranged between the upper handle and the lower handle to make the upper housing body cover the lower housing body elastically in an openable/closeable manner
Implementation Method 2
an upper hinging portion for rotary connection may be arranged at a joint between the upper housing body and the upper handle

AI summary
The disclosure provides a foldable portable excrement pick-up device. The device includes an upper housing and a lower housing which are combined to form a clip shape via a rotary shaft and a spring. The upper housing is composed of an upper handle and a cap-shaped upper housing body. The lower housing is composed of a lower handle and a bowl-shaped lower housing body. The upper handle and the lower handle are symmetrically arranged, the upper housing body and the lower housing body are hinged to form a clip shape in such a way that the rotary shaft penetrates through the upper hinging portion and the lower hinging portion, and the spring is arranged between the upper handle and the lower handle to make the upper housing body cover the lower housing body elastically in an openable/closeable manner.
