Solution Overview

Problem

Existing ceiling lamp capping devices are not suitable for insulating materials projected into the plenum or internal space of the ceiling, as they fail to provide effective thermal insulation and facilitate easy mounting.

Innovation Solution

A capping device with a set of spaced branches of the first type and flexible branches of a second type, which prevent insulating material from penetrating the internal volume, allowing for easy mounting and thermal insulation without hindering access to the lamp.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a capping device with spaced branches is used, then thermal insulation and heat dispersion are improved, but projected insulating material can penetrate inside the capping device

Engineering Contradiction:

Improvethermal insulationVSAvoidinsulating material penetration

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The capping device is divided into two types of branches: first type branches provide structural support and spacing for thermal insulation, while second type flexible branches fill the gaps to prevent material penetration. This segmentation allows each branch type to specialize in one function while working together to solve both problems.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second type branches are made flexible to conform to the insulating material and close gaps between branches. This flexibility allows the branches to adapt to the projected insulating material texture and prevent penetration while maintaining the thermal insulation function.

Inventive Principle:

Principle #30Flexible shells and thin films

2Object-affected harmful factors

If the inter-branch distance is reduced to prevent insulating material penetration, then protection from projected material is improved, but access to the lamp is hindered

Engineering Contradiction:

Improveinsulating material penetrationVSAvoidlamp access

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The second type branches are designed to be flexible rather than rigid, allowing them to dynamically adjust their position. They can be moved aside during lamp installation to provide access, then return to their gap-closing position to prevent insulating material penetration during normal operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flexibility parameter of the second type branches allows them to change their physical state between constrained (preventing penetration) and relaxed (allowing access). This parameter change enables the same structure to serve two opposing functions at different times.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If insulating material is removed to mount the lamp, then easy mounting is achieved, but thermal insulation is compromised

Engineering Contradiction:

Improvelamp mountingVSAvoidthermal insulation

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

The flexible second type branches are pre-positioned to close gaps and prevent insulating material penetration before the lamp is installed. This preliminary action ensures that the insulating material remains in place during lamp mounting, eliminating the need to remove it while maintaining thermal insulation.

Inventive Principle:

Principle #10Preliminary action
