Ceiling Holder With Inward Step For Module Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting functional modules on ceilings fail to balance speed, precision, and minimal damage to the ceiling surface, often resulting in suboptimal finishes where the module is not seamlessly integrated.
Innovation Solution
A holder design with an obliquely extending outer surface and an inward step on its inner surface, combined with leaf springs for secure clamping and a positioning plate for precise placement, ensures rapid and accurate installation with minimal risk of damage, allowing for a sleek and meticulous finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holder is designed with a simple flat inner surface for mounting the functional module, then the installation process is simple, but the precision of module placement and the sleekness of the finish are compromised
Solution Approach 1:
The holder inner surface is pre-configured with an upward extension and an inward step that protrudes into the ceiling opening. This preliminary geometric feature acts as a built-in positioning guide that automatically aligns and locates the functional module during insertion, eliminating the need for complex external positioning mechanisms while ensuring precise placement and a sleek finished appearance.
2Reliability
If the holder inner surface extends upward significantly to provide a mounting surface, then the module can be mounted securely, but contaminants may accumulate in the corner creating a messy finish
Solution Approach 1:
The solution introduces a third geometric dimension by adding the inward step that protrudes radially into the ceiling opening from the upward-extending holder inner surface. This creates a L-shaped profile that simultaneously provides secure mounting contact area while directing contaminants away from visible corners, as the step creates a drainage path for paint and plaster materials.
3Shape
If the holder is designed with a sleek profile where substantially only the functional module is visible, then the aesthetic finish is improved, but the holder structure becomes more complex
Solution Approach 1:
The holder is designed with differentiated local geometries: the outer surface maintains a simple sleek profile that is substantially invisible from the room side, while the inner surface features localized complexity with the upward extension and inward step. This local quality differentiation achieves the aesthetic goal of a clean ceiling finish while providing the necessary structural features for precise module mounting and contaminant management.
