Inductive Charging Mat with Retractable Cord and Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging mats are not portable, easily forgotten, and prone to damage due to exposed cords and lack of built-in batteries, making them difficult to use when electricity is unavailable and increasing the risk of loss.
Innovation Solution
A wireless mobile device charging mat with a built-in battery, retractable cord, and clip for attachment to bags or belts, featuring an inductive coupling charging circuit and a protective enclosure to prevent damage, allowing charging from an external power source or internal battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless charging mat is made portable and attachable to bags, then ease of operation and portability are improved, but device complexity increases due to integration of battery and protective enclosure
Solution Approach 1:
The patent combines multiple functions into a single integrated unit: the wireless charging mat, battery, protective enclosure, and attachment mechanism are merged into one portable device. This allows the charging mat to be carried anywhere while maintaining all necessary functions, directly resolving the contradiction between portability and structural complexity by making the complexity inherent to achieving portability.
Solution Approach 2:
The charging mat is designed to perform multiple functions: wireless charging, battery power storage, physical protection of components, and attachment to various surfaces. This multi-functionality justifies the increased structural complexity by providing comprehensive solutions in a single portable device, improving ease of operation through versatility.
2Ease of operation
If cords and connectors are exposed for charging connections, then ease of operation is improved, but reliability deteriorates due to damage from exposure to people, pets, or objects
Solution Approach 1:
The retractable cord mechanism allows the charging cable and connector to be nested within the protective enclosure when not in use. This nesting protects the exposed components from damage by people, pets, or objects while maintaining accessibility when needed, directly resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The protective enclosure serves as beforehand cushioning for the cord and connector components. By providing physical protection in advance before any potential damage can occur, the enclosure maintains reliability while still allowing operational access when needed.
3Productivity
If a wireless charging mat is left in outlets or locations for use, then productivity is improved, but loss of time occurs when the charger is forgotten or left behind
Solution Approach 1:
The attachment mechanism allows users to preliminarily secure the charging mat to bags or surfaces before leaving, ensuring the charger moves with the user. This preliminary action prevents the charger from being forgotten or left behind, eliminating the time loss associated with retrieving a forgotten charger while maintaining charging availability.
Solution Approach 2:
The built-in battery provides self-service capability, allowing the charging mat to function independently without requiring connection to external outlets. This autonomy ensures the charger is always available when needed, eliminating productivity interruptions and time losses associated with seeking power sources or retrieving forgotten chargers.
4Adaptability or versatility
If electricity is not available for charging, then adaptability is improved by using alternative power sources, but use of energy by moving object increases due to battery power consumption
Solution Approach 1:
The system changes its power source parameter from fixed external outlet to variable (external outlet or internal battery). This parameter change provides adaptability to different charging environments while the battery consumption is managed as a necessary trade-off for achieving charging flexibility when electricity is unavailable.
