Cantilever Load Detector With Swingable Slope for Caster Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load detectors are cumbersome to operate, particularly when trying to place casters under a bed, as they require simultaneous alignment on placement plates, making it tiresome to move heavy objects with casters.
Innovation Solution
A load detector with a beam-type load cell and a placement part featuring a slope that guides the subject onto the placement plate, where the slope is swingable or movable to facilitate easy alignment of casters, including a lever mechanism to accommodate the caster's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed placement plate is used, then the structure is simple, but it is difficult to align casters onto the placement plate
Solution Approach 1:
The placement plate is made movable relative to the load cell, allowing it to move in the width direction to accommodate casters of different positions. This dynamic adjustment enables easy alignment of casters onto the placement plate without requiring precise manual positioning, while the movable mechanism is designed to be simple and maintain stable measurement functionality.
2Productivity
If four casters must be simultaneously aligned on placement plates, then accurate load detection is achieved, but the operation becomes tiresome and time-consuming
Solution Approach 1:
The movable placement plate automatically adjusts its position to match the caster's location, eliminating the need for time-consuming manual alignment. This dynamic adaptation allows each caster to be independently and quickly positioned on its corresponding placement plate, significantly reducing setup time and improving productivity.
3Ease of operation
If the placement plate is made movable to facilitate caster alignment, then ease of operation improves, but device complexity increases
Solution Approach 1:
The placement plate is designed with a simple movable mechanism that allows it to move in the width direction relative to the load cell. This basic translational movement is sufficient to accommodate casters at different positions while maintaining a relatively simple overall structure that does not significantly increase device complexity.

AI summary
A load detector (100) includes: a beam-type load cell (21, 22) supported on a support base (11b, 12b) in a cantilever manner; and a placement part (30) connected to the beam-type load cell. The placement part has a placement plate (P30, P31, P33, P34, P35, P36) onto which a subject is placed, and a slope (SL) which is configured to guide the subject from a floor surface onto the placement plate. A forward end (SLT) of the slope is swingable about a first perpendicular axis perpendicular to the placement plate or a second perpendicular axis perpendicular to the slope, and/or is movable in a width direction of the placement plate.
