Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in maintaining a compact size while incorporating multiple rotating members for functional operations.
Innovation Solution
A dial device with a three-stage rotating member configuration, where at least two members are disposed in an opening portion of the housing, and a click mechanism with an elastic member and sphere provides tactile feedback, reducing the overall size and enhancing operational ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple rotating members are incorporated for functional operations, then operational versatility is improved, but apparatus size increases
Solution Approach 1:
The patent implements a nested configuration where the third rotating member is positioned inside the second rotating member, and both are arranged along a common first axis within an opening portion of the housing. This nesting approach allows multiple rotating members to share the same spatial footprint, providing diverse operational functions while maintaining a compact apparatus size.
Solution Approach 2:
The patent utilizes the radial dimension by arranging rotating members concentrically along a first axis within the opening portion. By transitioning from a linear arrangement to a radial/nested arrangement, multiple rotating members can coexist in a limited space without significantly increasing the apparatus volume, thus resolving the contradiction between versatility and size.
2Ease of operation
If a click mechanism with elastic member and sphere is added for tactile feedback, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The click mechanism utilizes the elastic member's inherent elasticity to automatically provide tactile feedback during rotation operations. The elastic member and sphere work together in a self-regulating manner, where the elastic deformation and recovery of the elastic member naturally generates the click sensation without requiring external control systems or complex mechanisms.
3Stability of the object's composition
If multiple holder members are used to support rotating members, then structural stability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the support structure into multiple separate holder members (first holder member, second holder member, third holder member), each responsible for supporting specific rotating members. This segmentation allows each holder member to be manufactured independently using standard fastening methods, and then assembled together, thereby maintaining structural stability while facilitating easier manufacturing and assembly.
