Solution Overview
Problem
Existing systems face challenges in efficiently reconfiguring and storing multiple three-dimensional panels and functional electrical components from a planar configuration into a folded configuration for improved portability and storability.
Innovation Solution
The development of rigidly foldable multi-body arrays connected by multiple hinges, allowing reconfiguration between unfolded and folded states, with hinges positioned in specific planes and protrusions providing necessary offsets to facilitate folding without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple three-dimensional panels are folded from a planar configuration into a folded configuration, then portability and storability are improved, but physical interference between panels during folding may occur
Solution Approach 1:
The patent introduces offset distances in the third dimension (perpendicular to the hinge plane) to separate panels that would otherwise interfere with each other during folding. Panels are positioned at different depths relative to the hinge plane, allowing them to fold without colliding while maintaining a compact form factor.
Solution Approach 2:
The patent uses offset positioning as an intermediary spatial arrangement between panels and the hinge plane. This offset acts as a mediator that prevents direct contact and interference between panels during the folding process, enabling smooth reconfiguration without physical collision.
2Ease of manufacture
If hinges are positioned in a single plane for simplicity, then manufacturing is easier, but folding between configurations may be constrained
Solution Approach 1:
The patent segments the hinge arrangement into multiple offset positions rather than using a single planar hinge line. Each hinge is positioned at a specific offset distance from the hinge plane, creating a segmented spatial distribution that enables versatile folding while maintaining manufacturing feasibility through standardized offset measurements.

Function Achieved in This Case
Enables efficient folding and unfolding of three-dimensional objects, enhancing storage and transportation capabilities by maintaining structural integrity and preventing physical interference during configuration changes.
Implementation Method 1
Each of the plurality of three-dimensional bodies may be associated with at least one of the hinges and pivotable about the at least one of the hinges between the unfolded and folded configurations
