Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a removable and flexible electrical connector that can securely connect and disconnect electronic devices without damaging them, especially for applications requiring frequent connections and disconnections.
Innovation Solution
A flexible electrical connector is provided, featuring an adhesive tape strip with electrically conductive traces that can be removably bonded to a substrate, using a stretch-releasable adhesive that allows for clean detachment without residue or damage, enabling the connector to maintain electrical contact while being easily removable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid electrical connector is used to create robust connections, then connection strength is improved, but flexibility and ease of removal deteriorate
Solution Approach 1:
The patent uses a flexible substrate (e.g., flexible printed circuit board) instead of rigid materials, allowing the connector to be bent and flexed during insertion and removal. This flexibility enables easy connection and disconnection while maintaining adequate electrical contact strength through the flexible traces and contacts.
2Ease of operation
If a removable adhesive tape strip is used, then ease of removal is improved, but connection strength deteriorates
Solution Approach 1:
The connector is segmented into a flexible substrate portion containing electrical traces and a separate adhesive tape strip portion. The adhesive tape provides removable bonding strength to hold the connector in place, while the flexible substrate provides electrical connectivity. This segmentation allows the adhesive to handle mechanical attachment while the flexible traces handle electrical connection.
3Adaptability or versatility
If frequent connections and disconnections are performed, then adaptability is improved, but device integrity deteriorates due to damage
Solution Approach 1:
The flexible substrate allows the connector to be repeatedly inserted and removed without causing damage to the electronic devices. The flexibility enables the connector to conform to slight misalignments and absorb mechanical stress during repeated operations, maintaining device integrity while providing high reusability.

AI summary
Flexible electrical connectors are provided to electrically connect electronic devices. The flexible electrical connector includes a removable adhesive tape strip having an adhesive surface thereof and an electrically conductive trace disposed on the adhesive tape strip. The flexible electrical connector engages an electronic device to form an electrical contact where the adhesive tape strip has an adhesive surface removably adhesively bonded to the substrate of the electronic device to at least partially cover the electrical contact.
