Slide Phone Lock Operator Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable telephone sets with a slide type structure face challenges in user operability, particularly in dark environments, as the position of the lock release operator cannot be easily recognized, hindering smooth operation.
Innovation Solution
Incorporating an illuminating means within the portable telephone set to illuminate the lock release operator from the inner side, utilizing a light-transmitting material in the vicinity of the operator and controlling LED light emission based on call arrival or operational states to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the portable telephone set uses a slide type structure with main and movable casings, then size reduction and compactness are achieved, but the lock release operator cannot be recognized in dark environments
Solution Approach 1:
The patent applies light emission (optical property change) to the lock release operator area to make it visible in dark environments. The illuminating means changes the optical state of the operator area by emitting light, allowing users to easily locate and operate the button regardless of ambient lighting conditions.
Solution Approach 2:
The patent introduces an illuminating means as an intermediary element between the lock release operator and the user's visual system. This intermediary component (light source) mediates the visibility issue by providing active illumination to the operator area, bridging the gap between the invisible button and the user's perception.
2Ease of operation
If an illuminating means is added to illuminate the lock release operator, then recognizability in dark environments is improved, but device complexity increases
Solution Approach 1:
The patent merges the illuminating means with the existing housing structure or operator area. By integrating the light source into the existing design framework rather than adding it as a completely separate component, the patent reduces the incremental complexity while achieving the visibility improvement.
Solution Approach 2:
The illuminating means is configured to automatically illuminate the lock release operator when needed (e.g., when the device is in a dark environment or when the operator is being used). This self-service approach eliminates the need for additional control mechanisms, reducing operational complexity while maintaining the visibility enhancement.
