Substrate Mounting Structure With Protruding Support Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate mounting methods require significant space for mounting holes, leading to potential instability and tilting of substrates during screw fixation, which can result in improper mounting and damage.
Innovation Solution
A substrate mounting structure that includes a substrate support portion with a screw hole and a protruding portion on the outer peripheral area, allowing the screw to clamp the substrate securely without the need for mounting holes, thereby reducing space requirements and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting holes are provided in the substrate for screw fixation, then the substrate can be securely mounted, but the space required for mounting increases and the substrate may tilt or become unstable
Solution Approach 1:
The invention moves the screw hole from the substrate to the substrate support portion, changing the spatial dimension of hole location. This allows the substrate surface to remain intact while achieving secure mounting through the support structure's outer peripheral portion, resolving the contradiction between mounting stability and space efficiency.
Solution Approach 2:
The invention separates the substrate into two functional parts: the substrate body that requires no holes, and the substrate support portion that contains the screw hole. This segmentation allows the substrate to maintain its integrity while the support structure provides the mounting function, eliminating the need for substrate holes and reducing mounting space.
2Ease of manufacture
If mounting holes are provided in the substrate, then screws can be inserted for fixation, but the substrate may tilt or become unstable during mounting
Solution Approach 1:
The screw hole is relocated from the substrate plane to the substrate support portion's outer peripheral surface, creating a three-dimensional mounting solution. This dimensional shift allows screw insertion without compromising substrate integrity, preventing tilting while maintaining manufacturing simplicity.
Solution Approach 2:
The substrate support portion acts as an intermediary between the substrate and the screw. It provides the screw hole and clamping surface, mediating the fixation process to ensure substrate stability without requiring holes in the substrate itself.
3Reliability
If the substrate is mounted using conventional methods with mounting holes, then fixation can be achieved, but the overall device size increases
Solution Approach 1:
The invention merges the substrate support function with the mounting function into a single integrated component. The substrate support portion simultaneously supports the substrate and provides the screw hole for fixation, eliminating the need for separate mounting holes in the substrate and reducing overall device volume.
Solution Approach 2:
By relocating the screw hole to the support portion's outer peripheral surface in three-dimensional space, the invention achieves reliable fixation without increasing the substrate's planar dimensions, thereby reducing the overall device footprint.

AI summary
A substrate mounting structure includes a substrate, a substrate support portion, a protruding portion, and a screw. The substrate has a first surface and a second surface that is a surface on an opposite side to the first surface. The substrate support portion includes a screw hole and is a section of an outer peripheral portion of the screw hole. The section comes into contact with the first surface of the substrate. The protruding portion is provided on at least a part of a section of the outer peripheral portion apart from the substrate support portion, and protrudes further in a direction from the first surface toward the second surface than the substrate support portion. The screw is screwed into the screw hole and clamps the substrate together with the substrate support portion.
