Touch Pen Holder with Wire Locking Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch pens provided with mobile devices are often lost or stolen when users leave them unattended, and existing solutions either increase the pen's cost or compromise its design, lacking a practical and competitive solution for secure attachment.
Innovation Solution
A touch pen holder unit featuring a storage container connected to a wire with a locking mechanism, comprising a body with locking grooves and a housing that securely fastens the pen, preventing unintentional detachment through a '⊏' shaped locking clip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable spool part is integrated into the touch pen to prevent loss, then loss prevention is improved, but the touch pen price increases and product competitiveness decreases
Solution Approach 1:
The patent extracts the loss prevention function from the touch pen itself and places it in a separate holder unit. The holder contains the cable spool mechanism and locking structure, while the touch pen only needs a simple head portion with a groove. This separation eliminates the need to integrate complex mechanisms into the pen, maintaining its simplicity and competitiveness while achieving reliable loss prevention through the holder's locking mechanism.
2Reliability
If a locking mechanism is added to secure the touch pen, then loss prevention is improved, but the attachment and detachment process becomes more complex
Solution Approach 1:
The patent employs a dynamic locking mechanism where the locking protrusion can freely move between locked and unlocked positions. During attachment, the protrusion automatically engages with the groove. During detachment, applying force to the wire causes the protrusion to disengage. This dynamic design allows simple one-handed operation for both attachment and detachment while maintaining secure locking during use.
3Reliability
If a secure fastening mechanism is implemented, then loss prevention is improved, but the structure becomes more complex
Solution Approach 1:
The patent segments the fastening system into distinct functional components: the holder body with cable spool, the locking mechanism with protrusion and groove, and the wire connector. Each component has a specific function and can be manufactured independently using simple processes. This segmentation achieves reliable secure fastening while keeping individual component structures simple and easy to manufacture.
