Cursor Key Frame Design Reducing Component Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic equipment, such as digital cameras, face challenges in assembly due to the complexity and number of components required for switches, leading to increased difficulty in manufacturing and reducing ease of assembly.
Innovation Solution
The design incorporates a first operating unit with a plurality of pressing portions and frames supported by the casing, allowing for reduced component count and simplified assembly, where the frames are strategically positioned between adjacent pressing portions to facilitate easier integration and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact spring is used to constantly bias the plunger, then the switching function is reliable, but the number of components increases and assembly becomes difficult
Solution Approach 1:
The frame integrates multiple functions: it supports the operating portion, provides the elastic biasing force through its own elasticity (replacing the separate contact spring), and serves as the structural backbone for the entire switch assembly. This merging of functions reduces the number of separate components while maintaining reliable switching operation.
Solution Approach 2:
The frame is designed as a multi-functional component that simultaneously acts as a structural support, an elastic element for biasing, and a mounting structure for the operating portion. This universal design eliminates the need for separate contact springs and support structures, simplifying the overall device complexity.
2Adaptability or versatility
If multiple components are used for the switch structure, then the functional requirements are met, but assembly ease deteriorates
Solution Approach 1:
By combining the support structure, elastic element, and operating portion mounting into a single integrated frame, the invention reduces the number of assembly steps. The frame is installed as one piece, automatically providing both structural support and elastic biasing, thereby improving assembly ease while meeting all functional requirements.
Solution Approach 2:
The frame is strategically segmented into two support portions that are positioned between adjacent pressing portions, allowing the structure to flex appropriately while maintaining stability. This segmentation enables the frame to fulfill multiple functions with a single component, improving both functionality and assembly ease.
