Solution Overview
Problem
Electronic devices face issues with cable connectors separating or damaging due to external impacts, and cables can irregularly buckle, affecting the device's appearance and touch sensation.
Innovation Solution
An electronic device design featuring a flat cable with a curved part and an elastic bracket made of elastic material, which applies an elastic contraction force to reduce tension on the cable and prevent buckling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is provided with slack to reduce tension, then the risk of connector separation or damage is reduced, but the cable may irregularly buckle and affect appearance and touch sensation
Solution Approach 1:
The patent applies curvature by forming a curved part in the cable at a specific position. This curved configuration allows the cable to accommodate slack without creating irregular buckles, as the pre-formed curve provides a controlled geometric shape that maintains appearance while reducing tension on the connector.
Solution Approach 2:
The patent implements preliminary action by pre-forming a curved shape in the cable during manufacturing, rather than allowing the cable to buckle irregularly during use. This advance preparation of the cable geometry ensures that when slack is introduced, it follows a predetermined curved path that maintains both reliability and appearance.
2Shape
If a cable is made taut to maintain appearance, then irregular buckling is reduced, but tension increases and may cause connector separation or damage under external impact
Solution Approach 1:
The curved part formed in the cable provides a geometric solution that allows the cable to remain taut in appearance while incorporating slack through the curve. This curvature enables the cable to maintain its shape without creating the tension that would lead to connector damage under impact.
3Shape
If the cable length is minimized to reduce buckling, then appearance and touch sensation are improved, but the cable becomes more susceptible to tension and connector damage
Solution Approach 1:
By forming a curved part in the cable, the patent creates a controlled geometric configuration that allows the cable to accommodate necessary length without creating irregular buckles. The curve provides a predetermined path for the cable that maintains appearance while distributing tension away from the connector.
