Rotatable Handle Key Assembly for Adjustable Finger Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device handles, such as those on mobile phones, have low universal applicability due to varying finger positions of different users, leading to inconsistent user experiences.
Innovation Solution
A handle design featuring a rotatable key assembly with snap slots and buckles, along with a resetting piece, allowing adjustable orientation and secure fixation to accommodate different finger positions, enhancing user experience and universality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the key is disposed in a fixed tilting state to facilitate pressing, then the ease of operation is improved, but the adaptability to different users with varying hand sizes and finger positions deteriorates
Solution Approach 1:
The key assembly is designed to be rotatable relative to the main body through a rotation mechanism, allowing the key's orientation to be dynamically adjusted. This enables the key to transition from a fixed tilting state to multiple adjustable orientations, resolving the contradiction by making the structure adaptive while maintaining ease of operation through rotational movement capability
Solution Approach 2:
The handle is designed with universal adaptability through the rotatable key assembly that can accommodate different finger positions and hand sizes. The key assembly can be positioned at multiple angles to serve different users, making the device universally applicable while maintaining ease of operation for each user configuration
2Adaptability or versatility
If the key assembly is made rotatable to adjust orientation for different users, then the adaptability is improved, but the device complexity increases due to additional rotation and fixation mechanisms
Solution Approach 1:
The key assembly is segmented from the main body, allowing independent rotation and positioning. This segmentation enables the key assembly to be adjusted without affecting the overall handle structure, reducing the complexity impact by isolating the adjustable component
Solution Approach 2:
A rotation mechanism acts as an intermediary between the key assembly and main body, providing a simple rotational interface. This intermediary mechanism enables orientation adjustment while maintaining a relatively simple overall structure, as the rotation mechanism serves as a straightforward connector rather than a complex system
3Stability of the object's composition
If the snap buckle and snap slot engage to fix the key assembly, then the stability of the key orientation is improved, but the ease of adjustment deteriorates due to the locking mechanism
Solution Approach 1:
The snap buckle and snap slot mechanism is designed to automatically engage and disengage through the rotation movement itself. As the key assembly rotates, the snap components naturally align and lock into place without requiring additional actions, making the adjustment process simple while maintaining stable fixation at the desired orientation

AI summary
A handle includes a main body, a key assembly, and a resetting piece. The main body includes an inner cavity and an opening. Snap slots are disposed on one of an inner wall of the inner cavity or a sidewall of the key assembly, and the sidewall faces the inner wall. At least one snap buckle is disposed on the other of the inner wall of the inner cavity or the sidewall of the key assembly. The buckle and the slot limit cooperate; when the buckle is in a first position, the resetting piece is in a first state, the slot disengages from the buckle, and the key assembly is rotatable relative to the body; when the buckle is in a second position, the resetting piece is in a second state, the slot engages with the buckle, and the key assembly is fixed relative to the body.
