Solution Overview
Problem
Conventional concrete utility vaults are cumbersome, prone to cracking, and difficult to stack, while plastic vaults lack stability and accessibility, necessitating a more efficient and modular solution for utility enclosures.
Innovation Solution
A folding, flared utility vault system with optional extension sections, featuring a base box and extension box connected via hinges, allowing for increased interior space, improved transportability, and enhanced stability through flared bottoms and compartments, enabling secure installation and expansion as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If concrete utility vaults are used, then stability and stacking are improved, but weight and bulk increase significantly
Solution Approach 1:
The utility vault is divided into a base box and one or more extension boxes that can be assembled together. This segmentation allows the vault to achieve concrete-like stability through proper base design while maintaining the lightweight advantage of plastic materials, as each segment can be optimized for its specific function.
Solution Approach 2:
The vault incorporates hinged panels that can transition between folded and extended configurations. This dynamic design allows the vault to be compact during transport (reducing effective weight impact) and expanded during operation (achieving required stability and volume), resolving the contradiction between mobility and stability.
2Weight of moving object
If plastic utility vaults are used, then weight and transportability are improved, but stability and stacking capability deteriorate
Solution Approach 1:
The base box is designed with pre-formed flared bottom walls and recesses that prepare the structure for stable stacking and equipment placement before extension boxes are added. This preliminary structural preparation ensures stability is built into the foundation, compensating for the inherent lightness of plastic materials.
Solution Approach 2:
The vault uses composite construction combining plastic panels with reinforced corners, flared bottom designs, and interlocking mechanisms. This composite approach maintains the lightweight plastic advantage while incorporating structural features that enhance stability and stacking capability, effectively bridging the gap between plastic and concrete performance.
3Ease of manufacture
If straight and rigid side walls are used, then manufacturing is simplified, but packaging and future equipment enclosure capability are limited
Solution Approach 1:
The vault is segmented into modular base and extension boxes with standardized interfaces. This segmentation allows straight-walled sections to be manufactured simply while the modular assembly provides adaptability, as extension boxes can be added to enclose additional equipment without requiring complex custom manufacturing.
Solution Approach 2:
The side panels incorporate hinged sections that allow the vault configuration to adapt to different equipment arrangements. The hinges enable panels to fold or extend, providing versatility in enclosing various equipment sizes and shapes while maintaining relatively simple manufacturing processes for each panel component.
4Ease of operation
If conventional utility vaults are used, then initial installation is achieved, but future equipment addition is limited due to space constraints
Solution Approach 1:
The vault is designed as modular base and extension boxes that can be assembled in various configurations. This segmentation enables easy initial installation of the base box and allows extension boxes to be added later to accommodate future equipment, providing both ease of operation and adaptability throughout the vault's lifecycle.
Solution Approach 2:
The standardized flanged areas and attachment mechanisms create universal interfaces that work for both initial installation and future expansions. The same base box and attachment design serve multiple functions across different installation scenarios and time periods, enabling both easy initial setup and flexible future equipment addition.

AI summary
A folding, flared utility vault or enclosure that may be used to protect public utility valves, electrical cables, switches, fiber optic cables, or the like is provided. The system generally comprises a base box having a front panel, back panel, and side panels. Alternative embodiments may further comprise an extension box having a front extension panel, back extension panel, and side extension panels. The various panels of the base box and extension box may have flared bottoms that prevent removal after installation. Additionally a user may attach extension boxes to the base box to increase the amount of storage area within the system.
