Solution Overview

Problem

Lighting control wall stations often suffer from misalignment of keypads relative to the wall plate due to variations in wall plate thickness, uneven installations, or improper attachment to electrical boxes, leading to undesirable depth positions.

Innovation Solution

A wall station with an adjustable position keypad interface assembly attached via adjustable fasteners, allowing for independent adjustment of the keypad's depth and tilt relative to the wall station housing to accommodate varying wall plate thicknesses and uneven installations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wall station is attached to the wall plate using fixed fasteners, then the installation is simple and quick, but the keypad depth position cannot be adjusted to accommodate variations in wall plate thickness and uneven installations

Engineering Contradiction:
Improvekeypad depth position adjustmentVSAvoidfastener adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fasteners are designed with adjustable characteristics, allowing the keypad interface assembly to be positioned at different depths. The fasteners can be moved along the mounting surface or have variable length adjustments, enabling the keypad to be aligned flush with the wall plate front surface despite variations in wall plate thickness and installation unevenness.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the wall plate thickness varies among different manufacturers, then the product has broader compatibility, but the keypad depth position becomes misaligned relative to the wall plate front surface

Engineering Contradiction:
Improvecompatibility with different wall plate thicknessesVSAvoidkeypad alignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The fastener system allows for parameter adjustment in terms of fastener position or length, which directly controls the depth position of the keypad interface assembly. By changing the fastener parameters (position along the mounting surface or effective length), the keypad can be precisely aligned with the wall plate front surface regardless of the wall plate thickness variation.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the wall station is installed in an uneven wall, then the installation location is flexible, but the wall plate becomes unevenly attached resulting in keypad misalignment

Engineering Contradiction:
Improveinstallation location flexibilityVSAvoidwall plate attachment evenness
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The adjustable fasteners enable dynamic compensation for uneven wall surfaces. By independently adjusting the fastener positions or lengths on each side of the mounting surface, the keypad interface assembly can be leveled and aligned properly even when the underlying wall plate attachment is uneven, maintaining precise keypad alignment with the wall plate front surface.

Inventive Principle:
Principle #15Dynamics

AI summary

A wall station control unit includes a wall station housing and a keypad interface assembly having a keypad. The keypad interface assembly is adjustably attached to the wall station housing by a first fastener and a second fastener. The first fastener extends through a first fastener hole in the wall station housing, and the second fastener extends through a second fastener hole in the wall station housing. The first fastener and the second fastener are adjustable to change a spacing between the keypad interface assembly and the wall station housing to adjust a position of the keypad relative to the wall station housing.
