Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footrests are often cumbersome to carry, difficult to assemble, and occupy a large storage space, lacking in portability and ease of use.
Innovation Solution
A modular footrest design featuring a base with foldable side walls and a container lid that can be configured into a compact briefcase shape, allowing for easy assembly and disassembly, with a removable height adjusting mechanism for customizable height support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional footrest designs are used, then stability and support are provided, but the footrest becomes burdensome to carry and occupies large storage space
Solution Approach 1:
The footrest is divided into multiple components: a base with four side walls, a bottom side, and a container lid with separate side walls and lid portions. These segmented parts can be folded flat for compact storage and transported separately, reducing the weight burden during carrying while maintaining structural integrity when assembled into a stable footrest configuration
Solution Approach 2:
The base components are designed to nest within the container lid when folded flat, creating a compact package that minimizes storage space. The side walls and bottom side of the base fit inside the container lid structure, allowing the entire footrest to be stored in a space-efficient manner while providing full stability when deployed
2Ease of manufacture
If traditional footrest designs are used, then support function is provided, but assembly becomes difficult
Solution Approach 1:
The footrest is divided into modular components (base with four side walls, bottom side, container lid with side walls and lid) that can be manufactured separately and assembled by folding. This segmentation allows for simpler manufacturing of individual parts and easier assembly through folding actions rather than complex fastening operations
Solution Approach 2:
The base and container lid are designed to join together when assembled, forming an integrated footrest structure. The joining mechanism combines multiple functions (structural support, stability, and footrest functionality) into a unified assembly that is straightforward to construct by bringing the pre-fabricated components together
3Volume of moving object
If traditional footrest designs are used, then foot support is provided, but storage space requirement increases
Solution Approach 1:
The base components (four side walls and bottom side) are designed to nest within the container lid when folded flat, creating a compact storage configuration. This nesting arrangement minimizes the volume required for storage and transport while maintaining the ability to assemble a full-sized functional footrest when needed
Solution Approach 2:
The footrest components are designed to fold from a three-dimensional structure into a two-dimensional flat configuration for storage. By collapsing the side walls and bottom side into a flat arrangement that fits within the container lid, the storage volume is dramatically reduced while the portability is enhanced through the compact flat-package design

AI summary
Systems of a footrest are described, along with a process for making the footrest. The footrest may include a base with at least four side walls connected by a bottom side. The base may be folded into a flat or box shape. The footrest may also include a container lid connected by a bottom lid and a top lid, and the base may be configured to join with the container lid. The base may also fit inside the container lid when folded, and the bottom lid of the container lid includes at least two semi-circular shaped depressions.
