Solution Overview

Problem

Conventional methods for covering air conditioner unit main bodies during installation result in unnecessary waste, as curing sheets and tapes are used temporarily and then discarded after decorative panels are mounted.

Innovation Solution

A packing material with a cover part and cut and bent up sections featuring slit parts is used to cover the unit main body's opening, allowing it to be fixed using protruding metal fittings, eliminating the need for curing sheets and tapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a curing sheet and tape are used to cover the opening part of the unit main body, then dust can be kept out during installation, but waste is generated after the decorative panel is mounted

Engineering Contradiction:
Improvedust contaminationVSAvoidwaste material
Core Design Contradiction:
Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

The packing material that originally served only for transport protection is redesigned to perform multiple functions: it continues to protect the unit main body from dust during installation and can be retained as part of the final assembly. The packing material is transformed from a single-use temporary covering into a multi-functional component that serves both protective and structural purposes throughout the installation process and beyond.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention combines the protective function of the curing sheet with the structural function of the unit main body by integrating the packing material into the overall assembly. The packing material is merged with the hanging clamp mechanism and the unit main body structure, creating a unified system where the packing material becomes an integral part of the installed air conditioner rather than a separate temporary element.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If a curing sheet is fixed with tape, then the opening part can be covered effectively, but the fixing process becomes complex and requires additional materials

Engineering Contradiction:
Improvedust contaminationVSAvoidfixing mechanism
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention extracts the fixing function from the packing material itself by incorporating hanging clamps that are already part of the unit main body. Instead of adding tape or other fixing materials to the packing material, the design utilizes the existing hanging clamp structure to perform the securing function, thereby simplifying the overall system and eliminating the need for additional fixing components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The packing material is designed to be self-fixing through the hanging clamp mechanism. The hanging clamp, which is already attached to the unit main body, automatically secures the packing material in place without requiring external fixing materials or complex assembly procedures. The system uses its own existing components to perform the fixing function.

Inventive Principle:
Principle #25Self-service

AI summary

Provided is a packing material which packs at least a unit main body of an air conditioner to be installed in a ceiling, the packing material including: a cover part for covering an opening part through which components inside the unit main body are exposed; and a cut and bent up part which has a slit part for inserting a protruding portion of the unit main body and fixes the cover part on the unit main body. The packing material can eliminate the need for a curing sheet and a tape for fixing the curing sheet while keeping out dust etc.
