Remote Control Pedestal Structure to Prevent Base Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load control systems lack a convenient and efficient way to control electrical loads, particularly lighting loads, without requiring significant electrical re-wiring or replacement of existing mechanical switches.
Innovation Solution
A remote control device with a rotating portion is designed to be placed on a horizontal surface, featuring a base that can be attached to a pedestal, which includes a mounting tab to prevent rotation and a fastener for secure attachment, allowing control of electrical loads through wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control device is placed on a horizontal surface without a pedestal, then ease of operation is improved, but stability of the device is worsened due to potential rotation and movement
Solution Approach 1:
The base is divided into functional segments: a recessed portion for receiving the pedestal platform, a flat portion for stable surface contact, and an opening for mounting tab insertion. This segmentation allows each part to perform its specific function in stabilizing the device while maintaining ease of operation.
Solution Approach 2:
The pedestal serves as an intermediary structure between the horizontal surface and the remote control device. It provides a stable platform with a defined top surface that interfaces with the base, preventing rotation and movement while allowing the device to remain easily operable on the surface.
2Ease of manufacture
If the base is made open to accommodate mounting tab, then ease of manufacture is improved, but strength of the base is worsened
Solution Approach 1:
The base exhibits local quality variations: the flat portion has increased thickness and structural reinforcement for strength, while the recessed portion and opening areas are optimized for manufacturability and pedestal accommodation. This localized differentiation allows the base to be both strong where needed and easy to manufacture where structural demands are lower.
3Stability of the object's composition
If the pedestal includes a platform with defined top surface, then stability of the device is improved, but device complexity is worsened
Solution Approach 1:
The pedestal platform serves multiple functions simultaneously: it provides a stable top surface for the base, defines a precise interface geometry for mounting, and creates a structural connection point for the mounting tab. This multi-functionality reduces the need for additional components, maintaining simplicity while achieving stability.

AI summary
A base may be configured to be attached to a pedestal. The pedestal may include a top plate, a bottom plate, and a mounting tab. The bottom plate may be configured to rest on a horizontal surface. The mounting tab may extend from the top plate (e.g., a platform on the top plate). The mounting tab may be configured to extend into an opening defined by the base. The mounting tab may be configured to prevent rotation of the base of the remote control device when the base is attached to the pedestal. The bottom plate may include a concave bottom surface. The concave bottom surface may include a recessed portion and a flat portion. The flat portion may be along an outer perimeter of the bottom plate. The flat portion may be configured to rest on the horizontal surface.
