Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power supply units in robot devices often fail due to heat generation in coils, making it difficult to repair and maintain these systems.
Innovation Solution
A wireless connector system that includes a first and second unit with transmission/reception parts and connector parts, allowing for easy attachment and detachment from arm parts, and featuring a protection part to prevent foreign matter intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power supply units are integrated into robot arm joints, then wireless power transmission is achieved, but repairability deteriorates due to fixed integration
Solution Approach 1:
The wireless power supply unit is divided into separable components: a first wireless power supply unit in the first arm part and a second wireless power supply unit in the second arm part. These units can be independently detached and replaced, transforming the system from a fixed integrated structure to a modular segmented structure that enables easy repair while maintaining reliable wireless power transmission through magnetic coupling between the separated units.
2Use of energy by moving object
If coil-based wireless power transmission is used, then power can be transmitted wirelessly, but heat generation causes failures
Solution Approach 1:
The harmful thermal effects are extracted and isolated from the power transmission function. The wireless power supply units are designed as detachable modules that can be removed and replaced when thermal damage occurs, separating the temporary thermal stress from the permanent power transmission capability. This allows the core power transmission function to be preserved while the damaged thermal-sensitive components are easily replaced.
3Device complexity
If transmission/reception parts are arranged inside the joint mechanism, then compact design is achieved, but accessibility for maintenance deteriorates
Solution Approach 1:
The transmission and reception parts are nested within housings that are attached to the arm parts, creating a compact layered structure. The first transmission part is housed in the first arm part, the second reception part is housed in the second arm part, and they face each other across the joint mechanism. This nested arrangement achieves compact integration while maintaining accessibility for maintenance through the detachable housing design.

AI summary
A wireless connector includes: a first unit attached detachably from the outside of a first object; and a second unit attached detachably from the outside of a second object. The first unit includes a first housing to which a first transmission/reception part and a first connector part are secured, the first connector part being attached to the first object and transmitting a to-be-transmitted target between the first connector part and the first object. The second unit includes a second housing to which a second transmission/reception part and a second connector part are secured, the second connector part being attached to the second object and transmitting a to-be-transmitted target between the second connector part and the second object. The first transmission/reception part and the second transmission/reception part are arranged so as to be separated from each other and opposed to each other to wirelessly transmit the to-be-transmitted target.
