Integrated Button Module for Multi-Directional Projector Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices require multiple independent touch buttons with different actuation directions, occupying internal space, complicating the device's appearance and increasing manufacturing costs due to the need for multiple openings.
Innovation Solution
A button module with a pressing element and an operation element, where the pressing element actuates a first electronic element in one direction and the operation element actuates a second electronic element in a different direction, with the operation element's driven part protruding from the pressing part, reducing space requirements and improving operational convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent touch buttons with different actuation directions are arranged separately, then each button can perform its specific function, but the internal space is occupied and the device appearance becomes complex
Solution Approach 1:
The patent combines multiple independent touch buttons with different actuation directions into a single integrated button module. The pressing element and operation element are arranged in different directions within one module, allowing multiple functions (power on/off, menu startup, focal length adjustment) to be performed through a single integrated structure rather than multiple separate buttons, thereby reducing internal space occupation
Solution Approach 2:
The integrated button module serves multiple functions simultaneously - it can perform power on/off operations, startup function menu operations, and focal length adjustment operations through different actuation directions. This multi-functional design eliminates the need for separate dedicated buttons for each function, achieving space savings while maintaining full operational versatility
2Adaptability or versatility
If multiple independent touch buttons are arranged separately, then each button can be operated independently, but the device appearance becomes complex and inconvenient to operate
Solution Approach 1:
Multiple independent buttons are merged into a single integrated button module with a unified appearance structure. The pressing element and operation element are integrated within one module, creating a compact and simple external appearance while maintaining independent operational capabilities through different actuation directions
Solution Approach 2:
The button module utilizes three-dimensional spatial arrangement by accepting actuation forces from different directions (pressing direction and operation direction). This dimensional approach allows multiple independent functions to be accessed through a single unified interface, simplifying the appearance while preserving operational independence
3Ease of operation
If the housing has many openings to accommodate physical buttons, then each button can be accessed, but the manufacturing process becomes cumbersome and high-cost
Solution Approach 1:
Multiple button openings in the housing are reduced to a single opening that accommodates the integrated button module. This consolidation simplifies the housing structure and manufacturing process, as fewer openings need to be precisely cut and finished, while the integrated module itself provides access to all button functions through its multi-directional actuation capability

AI summary
A button module includes a first electronic element, a pressing element, a second electronic element, and an operation element. The pressing element has a pressing part and a first actuation part. The pressing part has a through-hole. The pressing part moves relative to the first electronic element in a pressing direction. The pressing part drives the first actuation part to move when the pressing part moves so that the first actuation part actuates the first electronic element. The operation element has a driven part and a second actuation part. The second actuation part actuates the second electronic element. The driven part moves relative to the pressing part in an operation direction. The driven part drives the second actuation part to move when the driven part moves so that the second actuation part actuates the second electronic element. A projection device with the button module is also provided.
