Conductive Elastic Sheet Structure for Massage Head Mount Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage devices lack the ability to automatically detect whether a massage head is properly mounted, leading to potential power wastage and risk of accidental injury due to the head popping up during use.
Innovation Solution
A structure incorporating a sliding rod system with conductive elastic sheets that form a conductive path when the massage head is correctly mounted, using protruding contacts and abutting cylinders to ensure accurate detection of the inserted/pulled-out state through electrical signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no detection structure is added to the massage device, then the device structure remains simple, but the device cannot automatically identify whether the massage head is properly mounted, leading to power wastage and potential injury risks
Solution Approach 1:
The patent uses elastic sheets (thin films) as conductive elements that can be deformed by the massage head to establish or break electrical connections. The elastic sheets are mounted in grooves and can be compressed to create conductive paths between contacts, providing a simple yet effective detection mechanism without complex rigid structures
Solution Approach 2:
The elastic sheets act as intermediaries between the massage head and the control system. When the massage head is properly installed, it compresses the elastic sheets to create electrical contact, which then signals the control system to enable operation. This intermediary mechanism translates physical installation state into detectable electrical signals
2Reliability
If the massage head is not properly mounted, then the device can still operate, but this causes power wastage and may cause personal accidental injury due to the head popping up
Solution Approach 1:
The patent implements a feedback mechanism where the control system continuously monitors the electrical connection status through the elastic sheets. When the massage head is properly installed and creates contact through the compressed elastic sheets, the control system receives a confirmation signal and enables operation. If the head is not properly mounted and the connection is lost, the system automatically stops operation, preventing unsafe usage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures reliable detection of the massage head's mounted state, preventing power wastage and reducing the risk of injury by ensuring the massage head is securely attached before operation.
Implementation Method 1
When the massage head is fixed to the sliding cylinder and squeezes the first elastic sheet, the first elastic sheet is connected to the second elastic sheet
Implementation Method 2
The two mounting grooves are provided with a first elastic sheet and a second elastic sheet respectively

AI summary
A structure with a conductive elastic sheet and capable of automatically identifying an inserted/pulled-out state of a massage head includes a sliding rod structure including a sliding rod support and a sliding cylinder. The sliding rod support is arranged on the sliding cylinder, and mounting grooves with lengths equal to that of the sliding rod support are respectively provided at a left side and a right side of the sliding rod support. The two mounting grooves are provided with a first elastic sheet and a second elastic sheet respectively. When the massage head is fixed to the sliding cylinder and squeezes the first elastic sheet, the first elastic sheet is connected to the second elastic sheet. This application can help implement automatic recognition of the inserted/pulled-out state of the massage head. Once the massage head is pulled out, a removal state of the massage head can be recognized.
