Substrate Storage Housing with Directional Regulators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate storage structures for wireless communication modules in electronic devices, such as field devices, require complex assembly processes and often rely on potting material for substrate retention, which can be cumbersome and not easily adaptable to varying substrate dimensions.
Innovation Solution
A substrate storage structure with a housing featuring separate portions for thickness, width, and length direction regulators, including contact surfaces, slits, cushion members, and threaded connections, allowing for secure substrate positioning without the need for potting material, enabling simpler assembly and waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If potting material is used for substrate retention, then substrate positioning is achieved, but assembly process becomes complex and time-consuming
Solution Approach 1:
The housing is divided into a first portion and a second portion that can be separately assembled. The thickness direction regulator is integrated into the first portion, while the width direction regulator is integrated into the second portion, allowing modular assembly without potting material.
Solution Approach 2:
The patent replaces the chemical bonding mechanism of potting material with a mechanical regulation system consisting of thickness direction regulators, width direction regulators, and length direction regulators that physically constrain the substrate through contact surfaces and slits.
2Reliability
If housing is designed with multiple regulators for precise substrate positioning, then substrate retention is improved, but device complexity increases
Solution Approach 1:
Multiple regulator functions are merged into the housing structure itself. The thickness direction regulator, width direction regulator, and length direction regulator are all integrated as part of the housing, eliminating the need for separate positioning components.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural enclosure, implements substrate positioning through integrated regulators in all three directions, and enables modular assembly. The first and second portions each contain multiple regulator types, making the housing a multi-functional component.
3Ease of manufacture
If separate first and second portions are used in housing, then assembly is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The regulator structures (thickness direction regulator, width direction regulator, and length direction regulator) are pre-formed as integral parts of the first and second housing portions during manufacturing. This preliminary formation of precise regulatory features allows for easier final assembly while maintaining positioning accuracy.

AI summary
A substrate storage structure includes a substrate and a housing configured to store the substrate. The housing includes a thickness direction regulator configured to regulate a position of the substrate from both sides in a thickness direction, a width direction regulator configured to regulate the position of the substrate from both sides in a width direction, and a length direction regulator configured to regulate the position of the substrate from both sides in a length direction. The housing includes a first portion and a second portion connected to the first portion. The first portion includes the thickness direction regulator and a part of the length direction regulator. The second portion includes the width direction regulator and another part of the length direction regulator. This substrate storage structure can allow easy assembly.
