Metal Liquid Level Detector Support with Cutouts for Assemblability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal mounting stays for liquid level detectors have high rigidity, leading to increased mounting load and impaired assemblability, which can result in reduced detection accuracy due to potential rattling and looseness during assembly.
Innovation Solution
A liquid level detector support made of metal with a support body, thickness-direction fixing portion, and widthwise-fixing portions that engage with the detector to secure it in both thickness and width directions, incorporating cutouts to adjust rigidity and improve assemblability while maintaining fixing strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mounting stay is made of metal with high rigidity, then the fixing strength of the liquid level detector is improved, but the mounting load increases and assemblability deteriorates
Solution Approach 1:
The patent divides the single metal mounting stay into two separate components: a metal support body and a resin fixing piece. This segmentation allows the metal support body to provide structural strength and rigidity, while the resin fixing piece provides compliance and ease of assembly. The fixing piece is attached to the support body, creating a composite structure that combines the advantages of both materials.
Solution Approach 2:
The patent employs composite materials by combining metal and resin in a single assembly structure. The metal support body provides high rigidity and strength, while the resin fixing piece provides damping, compliance, and ease of assembly. This composite approach allows the assembly to exhibit both the strength of metal and the assembly-friendly properties of resin.
2Ease of operation
If the liquid level detector is installed with some looseness to reduce mounting force, then assemblability is improved, but rattling occurs and detection accuracy deteriorates
Solution Approach 1:
The resin fixing piece acts as a pre-installed cushioning element between the metal support body and the liquid level detector. This cushioning layer absorbs shocks and vibrations during assembly and operation, preventing rattling while maintaining secure fixation. The resin material's inherent damping properties provide this cushioning effect without requiring additional components.

AI summary
A liquid-level-detector support made of metal includes a support body engaged with a thickness-direction first portion of the liquid level detector and a fixing portion provided in the support body configured to fix the liquid level detector to the support body.
