Solution Overview

Problem

Concealable apparatus assemblies for boards or plates face issues with housing projection during rotation and gaps between the housing and the board or plate, leading to imperfect fitting and the need for additional modifications.

Innovation Solution

A support structure that is both rotatably and linearly receivable in the opening of a board or plate, equipped with guiding means for smooth rotation and linear movement, ensuring a flush fit without gaps and avoiding projection during intermediate positions, using guiding members like slots and pins, and driving means like motors for controlled movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the support structure is rotatably received in the opening, then the apparatus can be concealed at intermediate angular positions, but the housing projects above the board or plate during rotation

Engineering Contradiction:
Improveconcealment capabilityVSAvoidhousing projection
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The support structure is given dual mobility: rotational movement around the opening and linear movement along the normal direction. This two-dimensional movement space allows the housing to retract completely into the opening during rotation, eliminating projection above the board while maintaining concealment capability at intermediate positions

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the housing is made compact for rotation, then rotation is smoother, but gaps appear between the housing and the board or plate at stop positions

Engineering Contradiction:
Improverotation smoothnessVSAvoidfitting accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The support structure transitions from a static fitting problem to a dynamic solution. By allowing linear movement along the normal direction in addition to rotation, the housing can dynamically adjust its position to maintain perfect contact with the board or plate at stop positions, eliminating gaps while preserving rotation smoothness

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If a frame plate is added to cover gaps, then the fitting is improved, but the assembly complexity increases and the flat surface is no longer flush with the board

Engineering Contradiction:
Improvefitting qualityVSAvoidassembly structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The frame plate component is extracted and eliminated from the assembly. Instead of adding a frame plate to cover gaps, the support structure itself is given linear movement capability along the normal direction, allowing it to self-adjust and eliminate gaps without requiring additional components, thus maintaining simplicity and flush alignment

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention relates to a concealable apparatus assembly, comprising a support structure (5) supporting an apparatus (M) and rotatably receivable in an opening (1 a) of a board or of a plate (1) so that the apparatus (M) is accessible through said opening (1 a) from a first major surface of the board or plate (1) at a first angular position adopted by said support structure (5), and concealed for other angular positions adopted thereby, the support structure (5) having or supporting a flat surface (2) which remains flush with said first major surface of the board or plate (1) at a second angular position adopted by said support structure (5). The support structure (5) is also linearly receivable in said opening (1 a) so that it can move linearly according to an approaching/distancing direction with respect to the board or plate (1).
