Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining and maintaining the correct shelf height in modular shelving units is challenging due to the difficulty in identifying shelf notches, leading to non-uniform displays and potential exceeding of maximum height limits, especially with the base portion complicating vertical measurements.
Innovation Solution
A portable shelf height measurement device with an elongate measurement member featuring shelf notch indicator portions and a horizontal position indicator, which can be collapsible or telescoping, equipped with laser devices and a camera for easy alignment and verification of shelf notches, allowing for accurate installation and verification of shelf heights according to a preset plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual measurement methods are used to determine shelf height, then the installation process is simple, but the measurement precision and accuracy of shelf notch identification deteriorate
Solution Approach 1:
The patent replaces traditional mechanical measurement tools (tape measures, rulers) with optical measurement devices including laser distance meters and cameras. The laser distance meter emits laser beams to measure distances to shelf notches, while the camera captures images for visual verification, substituting mechanical measurement with optical fields to achieve higher precision without complex mechanical structures.
Solution Approach 2:
The patent introduces an intermediary processing system that receives data from multiple measurement devices (laser distance meter, camera, GPS) and processes this information through a processor. This intermediary system integrates data from different sources, performs calculations, and provides guidance to workers, simplifying the overall measurement process while maintaining high accuracy.
2Reliability
If workers manually determine shelf heights without guidance tools, then the device complexity is low, but the reliability of following the preset plan deteriorates
Solution Approach 1:
The patent implements a feedback system where the camera captures images of the installed shelves and the processor compares the actual installation with the preset plan. The system provides real-time feedback to workers through visual indicators or digital displays, allowing them to verify compliance and make corrections, thereby ensuring reliable adherence to the shelving plan.
Solution Approach 2:
The patent incorporates preliminary action by pre-programming the preset shelving plan into the system before installation begins. The GPS device pre-locates the shelving unit position, and the system pre-calculates the correct shelf heights based on the stored plan, providing workers with advance guidance information before they start the installation process.
3Measurement precision
If multiple measurement devices are used to verify shelf heights, then the measurement precision improves, but the ease of operation deteriorates
Solution Approach 1:
The patent merges multiple measurement devices (laser distance meter, camera, GPS receiver) into an integrated system that operates as a unified unit. The processor coordinates all devices simultaneously, combining their functions to perform comprehensive measurement and verification in a single operation, thereby maintaining high precision while simplifying the user interface and operation.
Solution Approach 2:
The system incorporates self-service features where the automated processing unit independently performs calculations, compares measurements with the preset plan, and generates verification results without requiring complex manual intervention. The system self-calibrates and self-verify, reducing the operational burden on workers while maintaining high measurement precision.

AI summary
In some embodiments, apparatuses and methods are provided herein useful to quickly and accurately determine shelf notch height for a shelving unit. This is particularly advantageous to determine whether shelves in the shelving unit were installed at the correct height and/or for installing shelves at desired heights. In some embodiments, a measurement member is provided with a bottom offset and shelf notch indicator portions. A horizontal position indicator can then be aligned with a desired shelf notch indicator portion and project outwardly therefrom towards a shelving unit to provide a visual indication of the height of a desired shelf notch.
