Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a wearable device that can accommodate tools usable by humans, animals, or mechanical devices, allowing them to enter and exit through simple operations without requiring a separate battery or external power source, and enabling adjustment of tool discharge angle and direction.
Innovation Solution
A wearable device with a wearing unit, housing, and power transmission unit that includes strings, links, and elastic members, allowing tools to be projected and retracted via user movement, with adjustable slope and direction mechanisms for tool discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are stored in bags or containers when not in use, then tools are protected and organized, but accessibility and ease of retrieval are reduced
Solution Approach 1:
The patent combines the tool storage function with the wearable device housing, integrating the tool into the device structure itself rather than requiring separate bags or containers. The tool is accommodated within the housing and can be quickly accessed through the opening mechanism, eliminating the need for separate storage accessories.
2Ease of operation
If tools are designed to be quickly accessible, then ease of operation improves, but device complexity and potential safety hazards increase
Solution Approach 1:
The patent implements a cover that can be preliminarily positioned to cover the opening of the housing, preventing accidental tool exposure. The cover mechanism is designed to be easily operable by the user, allowing quick access when needed while maintaining safety during storage or non-use conditions.
3Adaptability or versatility
If the wearable device accommodates multiple tools with different functions, then versatility improves, but device complexity and size increase
Solution Approach 1:
The patent designs the housing with a universal opening mechanism and accommodation structure that can hold different types of tools with various functions. The power transmission unit is also designed to work with multiple tool types, allowing the same wearable device housing to accommodate and operate different tools as needed.
4Power
If the power transmission unit uses multiple links and rotation shafts, then mechanical advantage and control improve, but device complexity increases
Solution Approach 1:
The patent divides the power transmission function into multiple independent components: a string for force application, a first link for force transmission, a rotation shaft for motion conversion, and a second link for tool actuation. This segmentation allows each component to be optimized for its specific function while maintaining overall system manageability and mechanical advantage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables tools to be easily inserted and removed without external power, allows for tool replacement, and provides protection and adjustment features for safe and versatile use.
Implementation Method 1
the tool may be returned into the housing by restoring force of the elastic member when the all or part of the any one of the two regions connected by the any one joint of the human joint, animal joint and mechanical joint is straightened
Implementation Method 2
a power transmission unit configured such that one end thereof is coupled to a part of the wearing unit and the other end thereof comes into contact with the tool, thereby moving in conjunction with the movement of the human body and transmitting force to the tool
Data Source
AI summary
A wearable device is disclosed. A wearable device according to an embodiment relates to a mechanism, including: a wearing unit configured to be mounted on any one of a human, an animal, and a mechanical device; a housing configured to be coupled to the wearing unit and to accommodate a tool having a predetermined function; and a power transmission unit configured such that one end thereof is coupled to a part of the wearing unit and the other end thereof comes into contact with the tool, thereby moving in conjunction with movement of the human, animal or mechanical device and transmitting force to the tool; wherein when a part of the human, animal, or mechanical device moves, the tool receives force from the power transmission unit and projects out of the housing, and to the utilization of the mechanism.
