Solution Overview
Problem
Conventional flat-panel reading lamps have limited illuminated and magnified zones, requiring frequent manual adjustments during full-text reading and making them inconvenient to use and carry.
Innovation Solution
A reading lamp with a splicable optical module composed of light guiding plates with Fresnel threads and uneven density lattice points, allowing for flexible assembly and a book support module with adjustable components for accommodating books of various sizes, enabling extended illumination and magnification without the need for frequent manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the area of the reading lamp is increased to expand the scope of reading, then the illuminated and magnified zones are improved, but the portability and convenience of carrying become extremely inconvenient
Solution Approach 1:
The optical module is divided into multiple detachable light guiding plates that can be spliced together. Each plate contains Fresnel threads and optical lattice points for illumination and magnification. Users can assemble multiple plates to expand the illuminated area or use fewer plates for portability, resolving the contradiction between reading scope and carrying convenience.
2Ease of operation
If the reading lamp uses a fixed optical module, then the structure is simple, but the illuminated and magnified zones are limited requiring frequent manual adjustments
Solution Approach 1:
The optical module transitions from a fixed structure to a dynamic, reconfigurable assembly. Multiple light guiding plates can be spliced together in different configurations to create a larger illuminated area, eliminating the need for frequent manual repositioning while maintaining structural simplicity through modular design.
3Area of stationary object
If the reading lamp uses a larger optical module to cover full text, then the reading scope is improved, but the device becomes cumbersome and requires frequent manual repositioning
Solution Approach 1:
By segmenting the optical module into multiple splicable light guiding plates, the system can achieve full-text coverage through assembly of multiple plates rather than relying on a single large plate. This reduces the need for frequent manual repositioning while maintaining a manageable device size that remains portable.
