Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveying methods require multiple processes and devices to transfer reference points between floors, increasing complexity and inefficiency in measurement work.
Innovation Solution
A leveling base with a pedestal, leveling plate, and a prism unit that retroreflects light beams, allowing for easy attachment and detachment of measuring devices, simplifying the installation and alignment of surveying instruments by enabling precise leveling and position transfer between floors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional surveying method is used to transfer reference points between floors, then the reference point can be transferred, but multiple processes and devices are required, increasing complexity
Solution Approach 1:
The patent combines the prism unit, leveling plate, and attachment/detachment portion into a single integrated leveling base assembly. This merging eliminates the need for separate horizontal target devices and reduces the number of installation steps while maintaining reference point transfer accuracy.
Solution Approach 2:
The leveling base serves multiple functions: it acts as a leveling device, a prism mounting platform, and a reference point transfer tool. The attachment/detachment portion allows various measuring devices to be mounted on the same base, making the system universal and reducing the need for multiple specialized devices.
2Adaptability or versatility
If multiple devices are used for surveying operations, then measurement functions are comprehensive, but the installation and alignment processes become more complex
Solution Approach 1:
The attachment/detachment portion is designed to accommodate various measuring devices including total stations, laser scanners, and GPS receivers. This universal mounting interface simplifies installation while maintaining comprehensive measurement capabilities across different device types.
Solution Approach 2:
The leveling plate with bubble level provides self-leveling capability, and the prism unit is pre-aligned with the vertical axis. This self-service design reduces the skill level and time required for installation and alignment operations.
3Measurement precision
If separate horizontal target devices are installed at reference points, then position measurement is enabled, but the overall device requirement and complexity increase
Solution Approach 1:
The prism unit is integrated directly onto the leveling plate, eliminating the need for separate horizontal target devices. This single integrated assembly performs both the reference point marking and the measurement target functions, reducing the total number of devices required.

AI summary
A leveling base includes the leveling base including a pedestal, a leveling plate provided to the pedestal via leveling screws such that the leveling is enabled, and a prism unit including a prism having retroreflective characteristics. The prism unit is provided on the leveling plate, the prism unit retro-reflects a light beam entering from a vertically lower side by the prism, a lower through-hole through which a light beam which enters/is reflected to the prism penetrates is provided in the pedestal, and an attachment/detachment portion which enables the attachment/detachment of a predetermined measuring device is provided on an upper surface of the leveling plate.
