Liquid Level Detection Device Cord Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid level detection devices face issues with electrical cords coming into frictional contact due to vibrations, leading to wear and potential short-circuits, which can compromise safety and reliability.
Innovation Solution
The design incorporates a frame body with a mounting plate and flange section where electrical cords are routed in a way that the second cord bypasses through a branch section from the mounting surface to the back surface, reducing the likelihood of cord contact and using terminals positioned on opposite sides to facilitate secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple electrical cords are positioned at one face side of the mounting plate, then the device structure is simplified and easier to manufacture, but the cords come into frictional contact with each other due to vibration, causing wear and potential short-circuits
Solution Approach 1:
The mounting plate is segmented into two distinct sides: the mounting surface side and the back surface side. Electrical cords are routed to exit at different sides, dividing the cord arrangement into separate spatial zones. This segmentation prevents cords from frictionally contacting each other while maintaining manufacturing simplicity, as the mounting plate structure itself provides the routing path.
Solution Approach 2:
Instead of arranging all electrical cords in the same two-dimensional plane (one face side), the invention utilizes the third dimension by routing cords to exit at opposite sides of the mounting plate. This dimensional change separates the cords in space, eliminating frictional contact while preserving ease of manufacture through the integrated plate structure.
2Volume of moving object
If electrical cords are routed closely together to save space, then the device size is reduced, but the cords are more susceptible to frictional contact and wear from vibration

AI summary
A liquid level detection device is configured so as to reduce or eliminate the contact between electrical cords led out of a detection section.A liquid level detection device (1) is provided with: a detection section (20) which detects the position of a liquid surface on the basis of the rotation of a rotation section (21) rotating as a float is displaced; a plate-like mounting plate section (12), one surface of which is a mounting surface (12a) to which the detection section (20) is mounted; a flange section (11) which is mounted to a tank for containing liquid; and first and second electrical cords (31, 32) which are led out of the detection section (20) toward the flange section (11). A branch section (122) which comprises a through-hole is provided in the mounting plate section (12). The second electrical cord (32) passes through the branch section (122) and is routed around from the mounting surface (12a) side of the mounting plate section (12) to the back surface (12b) side thereof.
