Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bracing and leveling devices for construction are cumbersome, inflexible, and require frequent adjustment or removal, leading to inefficiencies in use and storage, and pose risks due to their weight and instability, especially when handling prefabricated structural members.
Innovation Solution
A selectively deployable and actuable leveling device with an extendable frame that can be locked at various lengths, featuring a frame extension assembly and lock mechanism to stabilize and lift structural elements, allowing for adjustable deployment and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bracing and leveling devices are used to support structure forms, then the structure forms can be stabilized during pouring, but the devices are heavy and cumbersome requiring complete removal each time the structure form needs moving
Solution Approach 1:
The leveling device is divided into multiple telescoping sections that can be independently adjusted and locked. This segmentation allows the device to be extended or retracted to different lengths without requiring complete removal, enabling easy repositioning while maintaining stability during use.
Solution Approach 2:
The device incorporates telescoping mechanisms with locking pins that allow dynamic adjustment of the frame length. The locking pins engage with holes at various positions along the telescoping sections, enabling the device to adapt to different heights and positions while providing stable support when locked in place.
2Manufacturing precision
If conventional leveling devices are used, then structural members can be leveled, but the devices require frequent moving and adjustment which is labor intensive
Solution Approach 1:
The telescoping frame with multiple lockable sections allows precise height adjustment by selecting appropriate lock positions, maintaining leveling precision while reducing the need for complete device removal and reinstallation.
Solution Approach 2:
The device is designed to be pre-positioned and locked at the desired height before the leveling operation begins, eliminating the need for frequent adjustments during the process and reducing labor intensity.
3Reliability
If conventional bracing devices are used, then structure forms can be supported, but storage space is insufficient and devices get in the way when not in use
Solution Approach 1:
The telescoping sections of the frame nest within each other when the device is retracted, significantly reducing the storage space required. The compact nested configuration allows multiple devices to be stored in limited spaces while maintaining full support capability when deployed.
4Force
If prefabricated walls are lifted using conventional methods, then walls can be raised, but many workers are required which increases injury risk
Solution Approach 1:
The leveling device acts as an intermediary mechanical advantage system between the ground and the prefabricated wall. The telescoping frame with lever mechanisms provides force multiplication, allowing a smaller number of workers to safely lift and position heavy walls with reduced injury risk.

AI summary
A leveling device which can be selectively deployed and actuated to raise, lift, or stabilize a structural member or other element with respect to a support surface. In some embodiments, the leveling device may include an extendable device frame. The device frame may be selectively extendable to various lengths. A frame extension assembly may operably engage the device frame. The frame extension assembly may be configured to facilitate selective extension or lengthening and retraction or shortening of the device frame. The device frame may be selectively lockable at the selected extended length. In application of the device, the device frame may be deployed in place between a floor or other support surface and an elevated structural member to be raised, leveled, or stabilized. The frame extension assembly may be deployed from the pre-extended position to the extended position to extend the device frame and raise, level or stabilize the structural member.
