Retractable Charging Insert With Plug Receptacle for Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging cables for electrical devices often lie around loose and become a nuisance when not in use, causing inconvenience and potential damage.
Innovation Solution
A charging insert with a mounting plate and a reversibly retractable charging cable, featuring a receptacle with a charging plug that is positively or force-fittedly fixed and can be removed as needed, and an integrated winder that automatically retracts the cable when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging cable is left loose and accessible, then it is easy to access and use, but it lies around annoyingly and causes damage when not in use
Solution Approach 1:
The charging cable is nested within a receptacle structure when not in use, with the cable plug received in a recess of the mounting plate. The cable can be easily accessed when needed but is automatically retracted and protected when not in use, eliminating the nuisance of loose cables while maintaining accessibility.
Solution Approach 2:
The charging cable system transitions from a static loose state to a dynamic retracted state. The cable can be pulled out for use and automatically retracts when not needed, providing adaptability between accessibility and protection based on usage conditions.
2Reliability
If the charging plug is fixed in the receptacle, then it is securely held in position, but it cannot be removed when needed
Solution Approach 1:
The charging plug fixation system transitions from a static fixed state to a dynamic removable state. The plug is held securely in the receptacle during normal use but can be easily removed when needed, providing adaptability between secure positioning and removability based on usage conditions.
3Ease of operation
If the charging plug protrudes beyond the front of the mounting plate, then it is easily accessible, but it creates an unappealing visual appearance and potential damage risk
Solution Approach 1:
The charging plug is nested within a recess of the mounting plate when not in use, creating a flush appearance that is visually appealing and compact. The plug remains easily accessible when needed but is protected and aesthetically integrated into the mounting plate structure when retracted.
