Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to accommodate diverse body shapes due to fixed housing configurations, leading to discomfort and inefficiency in wearable devices.
Innovation Solution
Incorporation of a rotating member and adjusting member that allows for adjustable distance between housings, enabling rotation in two directions to change the distance between first and second housings, with locking structures for secure engagement and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed housing configuration is used, then the device structure is simple and easy to manufacture, but it cannot accommodate diverse body shapes leading to discomfort
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed housing configuration into an adjustable one. The distance between the first housing and second housing can be modified through the rotating member and adjusting member mechanism, allowing the device to adapt to different body shapes while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the distance between housings is fixed, then the manufacturing process is simple, but the device cannot provide customizable fit for different users
Solution Approach 1:
The patent segments the housing structure into adjustable components. The first housing and second housing are separated by a adjustable distance mechanism comprising moving members, a rotating member, and an adjusting member. This segmentation allows independent adjustment of the distance between housings without requiring complete redesign of the entire device, thus maintaining ease of manufacture while providing customizable fit.
3Adaptability or versatility
If adjustable distance mechanism is added, then adaptability to different body shapes is improved, but the device structure becomes more complex
Solution Approach 1:
The patent employs the nested doll principle by placing the rotating member and adjusting member within the housing structure. The adjusting member is rotatably coupled to the second housing and engages with the rotating member, creating a compact nested arrangement. This nesting minimizes the additional space required for the adjustment mechanism while providing full adjustability functionality.
Solution Approach 2:
The adjusting member serves multiple functions: it rotates to adjust the distance between housings, engages with locking structures to maintain the adjusted position, and can be operated by the user to modify the device configuration. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity.
4Reliability
If locking structures are implemented, then secure engagement is achieved, but the device complexity increases
Solution Approach 1:
The locking structures are designed to automatically engage and disengage based on the position of the adjusting member. When the adjusting member rotates to a specific position, the locking protrusions automatically align with and engage the locking grooves, providing secure engagement without requiring additional actuators or complex control mechanisms. This self-service approach maintains reliability while minimizing added complexity.

AI summary
An electronic device may include: a first housing; a second housing; moving members; a rotating member for adjusting the distance between the first housing and the second housing; an adjusting member including a first coupling part; a flange part; a first locking structure including a first locking part engaged with the first coupling part, and a second locking part that can move together with the first locking part; and a second locking structure including a plurality of first locking protrusions engaged with the second locking part, wherein the adjusting member changes the distance from a first distance to a second distance by rotating in a first rotation direction during a first state, changes the state to a second state by rotating relative to the first locking structure for a designated angle in a second rotation direction, and changes the distance from the second distance to the first distance by rotating in the second rotation direction during the second state.
