Solution Overview
Problem
Conventional vacuum cleaners lack versatility in usage modes, particularly in terms of portability and space-saving designs, as they are not easily convertible between carry, stand, and hang modes.
Innovation Solution
A vacuum cleaner design featuring a vacuum body assembly with a harness system that allows conversion between carry, stand, and hang modes, including a mount hook for hanging, a lock mechanism for secure attachment to a harness, and adjustable straps for user comfort, enabling flexible usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vacuum cleaner is designed with a fixed structure for stability, then it provides reliable suction performance, but it lacks versatility in usage modes and portability
Solution Approach 1:
The vacuum cleaner is divided into separable components: a vacuum body assembly and a removable harness assembly. The harness assembly can be attached or detached from the vacuum body assembly, allowing the vacuum cleaner to switch between handheld carry mode and upright stand mode. This segmentation enables versatility in usage modes without permanently increasing structural complexity.
Solution Approach 2:
The vacuum cleaner incorporates a dynamic configuration system where the harness assembly transitions between attached and detached states. A lock mechanism provides fixed stable positions (locked and unlocked) rather than continuous adjustment, enabling the vacuum cleaner to dynamically switch between different usage modes while maintaining structural integrity in each mode.
2Ease of operation
If a vacuum cleaner includes a harness assembly for carry mode, then portability is improved, but the mount hook for hanging storage becomes concealed and inaccessible
Solution Approach 1:
The mount hook is designed to change its positional state dynamically based on the harness assembly configuration. When the harness assembly is attached to the vacuum body assembly, the mount hook is concealed within the housing. When the harness assembly is removed, the mount hook becomes accessible and can be used for hanging storage. This dynamic repositioning resolves the conflict between harness functionality and mount hook accessibility without adding complex mechanical mechanisms.
3Adaptability or versatility
If the vacuum cleaner is designed to be convertible between multiple modes, then versatility is improved, but the risk of accidental mode changes or unintended detachment increases
Solution Approach 1:
The lock mechanism provides discrete stable states (locked and unlocked) rather than continuous or ambiguous intermediate states. This binary state system ensures that the harness assembly is either securely attached or completely removed, eliminating the risk of accidental partial detachment or unintended mode changes during normal operation.
Solution Approach 2:
The lock mechanism is designed to prevent unintended detachment before it can occur. The locking engagement provides a secure mechanical barrier that must be deliberately actuated to release, cushioning against accidental mode changes during transport or use of the vacuum cleaner.

AI summary
A vacuum cleaner includes a vacuum body assembly. The vacuum body assembly includes a housing having a base end, a mount hook connected to the housing, a debris container removably coupled to the housing, and a suction source. The suction source is able to draw air into the debris container. A harness assembly is removably connected to the vacuum body assembly. The vacuum cleaner is convertible between a carry mode, a stand mode, and a hang mode. The harness assembly is connected to the vacuum body assembly in the carry mode, and the harness assembly is to be worn by a user. The base end of the vacuum body assembly may rest on a support surface in the stand mode. The hook of the vacuum body assembly may hang the body assembly from a mount structure in the hang mode.
