Integration of a light set with a flexible conductor and multiple light emitters attached to the device's frame, which outlines its shape and enhances visibility through controlled illumination patterns, using a power source and controller for adjustable light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light set is integrated into the mobility device, then visibility in low light conditions is improved, but device complexity increases
Solution Approach 1:
The light set is integrated into the mobility device frame by combining the light emitters, conductor, and power source into a unified assembly that becomes part of the device structure. This merging approach improves visibility while managing complexity through consolidation rather than separate components.
Solution Approach 2:
The light set serves multiple functions: it provides illumination for visibility, acts as a safety feature to prevent accidents, and can be configured in different emission patterns. This multi-functionality justifies the added complexity by delivering multiple benefits from a single integration.
2Difficulty of detecting and measuring
If multiple light emitters are added to outline the device shape, then recognition ability is improved, but manufacturing complexity increases
Solution Approach 1:
The light set is divided into multiple discrete light emitters that can be individually positioned along the frame to outline specific shapes and features. This segmentation allows for flexible configuration to enhance recognition while simplifying the manufacturing process by using standardized emitter components.
Solution Approach 2:
Light emitters are strategically positioned at specific locations along the frame where they provide the most effective visual outlining. This local quality approach ensures that recognition ability is maximized by placing light sources where they are most needed, rather than uniformly distributing them.
3Adaptability or versatility
If the light set is made adjustable with controlled illumination patterns, then versatility is improved, but device complexity increases
Solution Approach 1:
The light set incorporates adjustable illumination patterns that can be dynamically controlled through the conductor and power source system. This dynamic capability allows the light set to adapt to different usage scenarios while managing complexity through a centralized control architecture rather than multiple independent systems.

AI summary
A personal mobility assistance device has a frame that includes a linkage mechanism, a first frame portion, and a second frame portion. A first rigid frame component of the first portion is connected to a second rigid frame component of the second portion by the linkage mechanism and movable relative to the first rigid frame component such that the apparatus is capable of being configured in a plurality of apparatus configurations. A plurality of light emitters has a first set of light emitters electrically connected to a conductor and affixed to the first frame portion and a second set of light emitters electrically connected to the conductor and affixed to the second frame portion. When the light set is in an active on state, the conductor forms an electrical connection between a power source and the plurality of light emitters to activate the plurality of light emitters to emit light.
