Battery Sensor Positioner for Accurate Mounting and Rotation Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery sensors face challenges in accurate mounting to batteries due to rotation around the battery post during tightening, leading to potential interference with vent plugs and reduced space utilization in engine rooms.
Innovation Solution
A positioner with a sensor-fixing part and a rotation-blocking part is used to securely attach the battery sensor to the battery, preventing rotation and ensuring accurate positioning through a fitting section, lid section, hinge part, lock mechanism, and reinforcement ribs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery sensor is arranged above the battery to improve space utilization, then the sensor does not protrude laterally and interferes less with surrounding parts, but the sensor may rotate around the battery post during tightening, reducing mounting accuracy
Solution Approach 1:
A positioner is introduced as an intermediary device between the battery sensor and the battery post. The positioner includes a rotation-blocking part that contacts the side surface of the battery to prevent rotation, while the sensor-fixing part secures the battery sensor. This intermediary structure enables accurate mounting without lateral protrusion, resolving the contradiction between space utilization and mounting accuracy.
2Reliability
If the battery sensor is mounted tightly to ensure secure attachment, then the sensor connection is reliable, but the sensor rotates around the battery post during tightening, causing potential interference with vent plugs
Solution Approach 1:
The positioner acts as a mediator that prevents rotation during the tightening process. The rotation-blocking part contacts the battery's side surface to stop rotational movement, while the sensor-fixing part ensures secure attachment of the battery sensor. This allows tight mounting for reliability without causing harmful interference with the vent plug.
Solution Approach 2:
The positioner applies preliminary anti-action by blocking rotation before the tightening process completes. The rotation-blocking part is positioned to contact the battery side surface in advance, preventing rotational movement that would otherwise occur during bolt tightening, thereby avoiding interference with the vent plug.
