Packable modular camp toilet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camp toilet solutions for backcountry activities such as small craft river running, packrafting, and backpacking are bulky and non-essential items are often left behind due to space and weight limitations, leading to unsanitary conditions.
Innovation Solution
A lightweight, packable, modular camp toilet composed of interchangeable components that can be easily assembled and disassembled, allowing an adult human waste bag to be used comfortably and hygienically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing camp toilet solutions are used, then human waste disposal is possible, but the equipment is bulky and occupies excessive space and weight
Solution Approach 1:
The camp toilet is divided into separate modular components: a seat assembly and leg assemblies that can be detached and stored separately. This segmentation allows the toilet to be disassembled into compact parts that fit within limited backpack space, directly resolving the volume constraint while maintaining full toilet functionality when assembled.
Solution Approach 2:
The toilet structure transitions from a static, permanent form to a dynamic, reconfigurable system. The legs can be folded against the seat or completely detached, allowing the toilet to adapt between a stable three-legged configuration during use and a compact, portable configuration during transport.
2Ease of operation
If existing camp toilet solutions are used, then human waste disposal is possible, but the equipment is heavy and exceeds weight limits
Solution Approach 1:
By separating the toilet into modular components, the user can selectively pack only essential parts based on trip requirements. The seat assembly can be carried with minimal accessories for lightweight trips, while additional leg assemblies can be added for extended use, allowing flexible weight management.
Solution Approach 2:
The leg assemblies are extracted as separate, removable components rather than being permanently attached to the seat. This extraction allows the user to carry only the essential seat assembly for minimal weight, adding legs only when toilet functionality is required.
3Ease of operation
If existing camp toilet solutions are used, then human waste disposal is possible, but the equipment cannot be easily packed for transport
Solution Approach 1:
The segmented design with standardized connection interfaces allows rapid assembly and disassembly. The seat assembly features clearly marked attachment points and compatible leg interfaces, enabling users to configure or pack the toilet without complex procedures or specialized tools.
Solution Approach 2:
The dynamic, reconfigurable structure allows the toilet to be quickly transitioned between assembled and packed states. The legs fold flat against the seat or detach completely, creating a compact bundle that can be easily integrated into backpack arrangements without complex packing procedures.
4Volume of moving object
If a modular design is used, then the toilet can be disassembled for transport, but the assembly and disassembly process requires time and effort
Solution Approach 1:
The segmented modular design with standardized interfaces enables quick connection and disconnection of components. The seat assembly includes pre-positioned attachment points and the legs feature matching connection mechanisms, allowing assembly or disassembly through simple, repetitive actions rather than complex procedures.
Solution Approach 2:
The connection interfaces are pre-configured during manufacturing with aligned attachment points and integrated fastening mechanisms. This preliminary preparation eliminates the need for measurement, alignment, or complex fastening operations during field assembly or disassembly, significantly reducing the time and effort required.

AI summary
A camp toilet may include at least three legs each having a bracket with at least two threaded apertures for receiving at least two fasteners, each fastener positioned in a different one of the at least two threaded apertures, and a seat having a flat surface and forming (a) an internal aperture and (b) evenly positioned around the flat surface for each of the at least three legs, at least two open-ended slots each sized and shaped to receive the at least two fasteners, wherein the fasteners secure the leg to the seat when positioned within the at least two slots and tightened. The camp toilet is modular, lightweight, and easily disassembled and packed for transport.
