Switch Control Module Tamperproof Sealing via Merged Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices, such as water gauges and electric meters, face challenges in having tamperproof and waterproof switch control modules that allow for complex setting changes without damaging the device due to environmental moisture and size enlargement issues with protective covers.
Innovation Solution
A switch control module comprising a housing, control assembly, linkage unit, and positioning units, where the linkage unit includes a rod, holding pin, and sealing member to rotate the shaft and seal the opening, enabling operation mode changes while preventing unauthorized access and moisture damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover with retainer bolts and lead seal is used to prevent unauthorized access, then tamperproof quality is improved, but device size is enlarged and cost increases
Solution Approach 1:
The patent combines the protective cover structure with the switch control module into an integrated unit. The housing of the switch control module serves as both the functional enclosure and the protective element, eliminating the need for separate protective covers, retainer bolts, and lead seals while maintaining tamperproof quality.
2Reliability
If a protective cover with retainer bolts and lead seal is used to prevent unauthorized access, then tamperproof quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the protective cover function with the switch control module housing, eliminating the need for separate protective covers, retainer bolts, and lead seals. This integration reduces the number of components and assembly steps, thereby lowering manufacturing cost while maintaining tamperproof quality.
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
The module allows for complex setting changes while maintaining device integrity by preventing unauthorized access and protecting against moisture, enhancing durability and operational flexibility.
Implementation Method 1
the sealing member is compressed by the abutting structure so as to seal the opening
Implementation Method 2
a shaft that is rotatable about a main axis, wherein the main axis passes through the opening
Implementation Method 3
The linkage unit is configured to drive the shaft to rotate so as to change the operation mode of the control module

AI summary
A switch control module is provided, which includes housing, a control assembly, a linkage unit, and a number of positioning units. The housing defines an accommodating space and has an opening. The control assembly is positioned in the accommodating space and has a shaft that is rotatable about a main axis. The linkage unit passes through the opening and is connected to the shaft in a movable manner. The positioning units are positioned at the edge of the opening. Each of the positioning units extends radially and outwardly with the main axis as a center and is projected in a direction along the main axis. The linkage unit is selectively connected to one of the positioning units and is configured to drive the shaft to rotate so as to change the operation of the control module.
