Adjustable Lighted Bookmark With Hinged Clips And Bearings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bookmarks often slide out of books, fail to maintain the reader's place, and lack lighting, leading to difficulties in tracking progress and reading in low-light conditions.
Innovation Solution
An adjustable lighted bookmark with a telescoping spine, hinged upper and lower arms, and clips with bearings that allow page turning and a retractable light for improved illumination, ensuring secure placement and readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bookmark is used, then the reader can mark their place, but the bookmark slides out of the book causing loss of place
Solution Approach 1:
The bookmark is divided into multiple functional segments: a base portion that inserts into the book, hinged arms that can be positioned, and clips that secure pages. This segmentation allows each part to perform its specific function - the base anchors the bookmark while the clips hold pages, preventing the bookmark from sliding out while maintaining ease of use.
Solution Approach 2:
The bookmark incorporates hinged arms that can dynamically adjust to different book thicknesses and page positions. The hinges allow the arms to move and adapt, providing both secure retention and ease of operation as the bookmark can be easily positioned and adjusted without forcing or damage.
2Reliability
If a bookmark holds the book open, then the reader's place is maintained, but pages cannot be turned
Solution Approach 1:
The hinged arms and clips are designed to be dynamic rather than fixed. The clips can be opened and closed to release and secure pages, while the hinged arms can be repositioned. This allows pages to be turned by simply opening the clips, maintaining the reader's place without preventing page turning.
Solution Approach 2:
The clips act as intermediaries between the bookmark structure and the pages. They provide a mechanical interface that secures pages when closed but allows easy release when opened, enabling page turning while maintaining place retention during reading.
3Illumination intensity
If lighting is added to the bookmark, then reading in low-light conditions is improved, but device complexity increases
Solution Approach 1:
The lighting function is merged with the bookmark structure by integrating the light source into the base portion of the bookmark. This combination provides illumination without requiring a separate device, and the light can be powered by a small battery compartment built into the bookmark, adding functionality while maintaining relatively simple construction.
Solution Approach 2:
The bookmark is designed with multi-functionality, serving as both a place-marker and a lighting device. The same structural elements that provide mechanical support for the clips and hinges also house the battery compartment and light source, reducing overall complexity while providing multiple functions.

AI summary
An adjustable lighted bookmark. The adjustable lighted bookmark has a spine with an upper end opposite a lower end. A pair of upper arms, hingedly secured to the upper end of the spine, and a pair of lower arms, hingedly secured to the lower end of the spine, define a space therebetween. A pair of upper clips are disposed distally on the pair of upper arms and a pair of lower clips are disposed distally on the pair of lower arms. The pair of upper clips and the pair of lower clips are oriented inwardly towards the space between the upper and the lower arms. Each clip of the pair of upper clips and the pair of lower clips has at least one bearing on an internal surface thereof. A light extends from the spine which provides lighting on a piece of reading material secured by the adjustable lighted bookmark.
