Solution Overview
Problem
Conventional wall-mounted air conditioners face challenges in improving workability during installation, reducing depth size, and enhancing energy saving performance due to space constraints and interference between installation members and the heat exchanger, which limits the size and volume of the heat exchanger.
Innovation Solution
A wall-mounted air conditioner design featuring a holding member that rotates upward and is stored within the main body casing, allowing for an inclined installation state without interfering with the piping space, enabling a larger heat exchanger cross-sectional area and efficient use of depth storage space, while reducing the unit's depth size and improving installation workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a holding member is provided on the back side of the heat exchanger to support the interior unit during installation, then installation workability is improved, but the heat exchanger cross-sectional area is reduced
Solution Approach 1:
The holding member is positioned in the second side end portion of the main body casing, utilizing the lateral dimension rather than the depth dimension behind the heat exchanger. This spatial repositioning allows the holding member to support the unit during installation without encroaching on the heat exchanger's cross-sectional area, thereby resolving the contradiction between installation workability and heat exchanger size.
2Ease of operation
If the holding member is fixed in an extended position to facilitate piping work, then installation workability is improved, but the depth size of the interior unit increases
Solution Approach 1:
The holding member is designed to be rotatable about a horizontal shaft, transitioning between an extended position during installation that facilitates piping work, and a retracted position within the main body casing for the final installed state. This dynamic capability allows the holding member to provide installation support without permanently increasing the depth size of the interior unit.
Solution Approach 2:
The holding member is contained within the main body casing when not in use, with the casing serving as a storage space for the holding member. This nesting arrangement allows the holding member to be stored inside the main body, preventing any permanent increase in the depth size of the interior unit while still providing support functionality during installation.
3Stability of the object's composition
If the locking unit is disposed at the upper portion of the mounting plate for stable locking, then installation stability is improved, but the holding member positioning becomes more constrained
Solution Approach 1:
The support function is segmented between two distinct components: the locking unit disposed at the upper portion of the mounting plate for stable locking, and the holding member disposed at the second side end portion for lateral support during installation. This segmentation allows each component to perform its specific function independently, maintaining installation stability while simplifying the positioning requirements for the holding member.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances workability during installation, reduces the depth size of the indoor unit, and improves energy saving performance by allowing a larger heat exchanger volume and easier piping work, while maintaining stability and reducing material costs.
Implementation Method 1
The holding member includes a rotational shaft unit using the horizontal shaft as an axis. The holding member rotates upward to be contained in the main body casing.

AI summary
A wall-mounted air conditioner includes: a main body casing including first and second side end portions disposed respectively on opposite sides to each other in a horizontal direction, and a central portion disposed between the first and second side end portions; a heat exchanger disposed in the central portion of the main body casing; a fan motor disposed in the first side end portion of the main body casing; a mounting plate having a locking unit for locking the main body casing, the locking unit being disposed at an upper portion of the mounting plate; and a holding member configured to hold main body casing in an inclined state where the main body casing is locked to the locking unit during installation. The main body casing includes a holding member containing unit configured to contain the holding member, and a rotational supporting unit having a horizontal shaft engaged with the holding member. The holding member is disposed in a position, the position being in the second side end portion of the main body casing and on a side of a back surface of the main body casing. The holding member includes a rotational shaft unit using the horizontal shaft as an axis. The holding member rotates upward to be contained in the main body casing.
