Keyboard Panel Attachment Structure for Warping Correction

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices and keyboard instruments face challenges in securely attaching components like console panels and speaker covers, particularly due to warping issues during manufacturing, which affect the alignment and stability of these parts.

Innovation Solution

The use of a top member with a wing-shaped male portion and a speaker cover with a corresponding flat female portion, along with pins and pin insertion holes, allows for secure attachment and correction of warping, ensuring proper alignment and stability between the console panel and speaker cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a positioning pin is inserted into an insertion hole to correct warping of the side plate, then the warping correction is effective, but the insertion direction is limited to being parallel to the flat surface of the side plate

Engineering Contradiction:

Improvewarping correctionVSAvoidinsertion direction flexibility

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent introduces a second male portion extending in a second direction different from the first direction, and a second female portion corresponding to it. This adds a dimensional aspect to the attachment mechanism, allowing attachment in multiple directions rather than being limited to a single insertion direction parallel to the flat surface.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If multiple attaching members are used to ensure stable attachment, then the attachment stability is improved, but the device structure becomes more complex

Engineering Contradiction:

Improveattachment stabilityVSAvoidstructure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines multiple attaching members (first attaching member with first male portion, second attaching member with second male portion) into a single integrated attaching member structure. This merging approach maintains the stability benefits of multiple attachment points while reducing overall structural complexity and the number of separate components.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An electronic device includes an attaching member including a first attaching member having a first male portion protruding in a first direction from an outer circumference of the first attaching member, and a second attaching member having a first female portion corresponding to the first male portion, and an attached member to which the attaching member is attached. The attaching member includes either one of a second male portion extending in a second direction different from the first direction and a second female portion corresponding to the second male portion. The attached member includes the other of the second male portion and the second female portion.
