Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children face challenges in using toilets outdoors due to infection risks, spatial constraints, and difficulty in accessing restrooms, leading to issues with clean defecation and skin irritation, especially when engaging in outdoor activities.
Innovation Solution
A bag-fastening type portable toilet with rotatable covers that can be easily installed and folded for compactness, featuring a container-like body with arch-shaped members and hinge-connected toilet covers to facilitate clean defecation from a stable posture, allowing for quick setup and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a portable toilet is designed with rigid structure for stability, then it provides stable posture for defecation, but it increases volume and becomes difficult to store in handbag
Solution Approach 1:
The portable toilet employs a flexible, collapsible structure that transitions between a stable three-dimensional configuration during use and a compressed flat state for storage. The body and covers are designed with flexible materials that maintain structural integrity when assembled but can be collapsed without damage, enabling the toilet to adapt its volume dynamically based on operational needs.
Solution Approach 2:
The portable toilet components are designed to nest within each other when collapsed. The first and second covers can be folded inward, and the body members can be collapsed concentrically, allowing the entire structure to be compressed into a compact form that fits within a handbag while maintaining full functionality when deployed.
2Reliability
If a portable toilet is designed with complex fastening mechanism for secure bag attachment, then it ensures hygienic waste handling, but it increases device complexity and reduces ease of operation
Solution Approach 1:
The portable toilet incorporates self-fastening mechanisms where the bag attachment system automatically secures itself through integrated clips, hooks, or snap-fit components. The bag can be attached to the body or covers without requiring additional tools or complex manual operations, allowing users to quickly secure waste containment while maintaining hygienic standards through reliable automatic fastening.
3Stability of the object's composition
If a portable toilet is designed with large size for child comfort, then it provides stable posture for defecation, but it becomes difficult to carry and store during outdoor activities
Solution Approach 1:
The portable toilet is designed with a dynamic structure that expands to provide adequate size for child comfort during use, then collapses to a compact, lightweight form for carrying. The flexible materials and collapsible geometry allow the toilet to transition between these states, ensuring that the weight burden on parents is minimized during transport while maintaining sufficient dimensions for stable child defecation when deployed.
4Volume of moving object
If a portable toilet is designed with rotatable covers for compact folding, then it reduces volume for storage, but it increases device complexity
Solution Approach 1:
The portable toilet is divided into separate modular components including the body and multiple covers that can independently rotate and fold. Each cover is connected through simple hinge joints that allow individual manipulation, enabling the structure to be collapsed into a compact configuration for storage while keeping the overall device complexity manageable through modular design and simple connection mechanisms.

AI summary
A portable toilet comprises a container-shaped body of which the top surface is opened and the inside is empty. A first toilet cover is provided on the opened top surface and formed in an arch shape, and a second toilet cover is disposed on the opened top surface so as to be symmetrical to the first toilet cover, wherein each of the first toilet cover and the second toilet cover rotates with respect to the body such that each one end portion of the first toilet cover and the second toilet cover can be spaced apart with respect to the body.
