Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors require complex threading and screw removal processes for replacing light source devices, making the replacement process difficult and time-consuming.
Innovation Solution
A projector design featuring a resilient member formed by bending a bar-shaped metal component, which can rotate to facilitate easy installation and removal of the light source device by transitioning between open and close positions, allowing for simple rotation-based replacement without the need for screw removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the light source device to the optical component housing, then the light source device can be securely fixed, but the replacement process becomes complicated and time-consuming
Solution Approach 1:
The resilient member is designed to be movable between a first position (engaging with the light source device) and a second position (disengaged), allowing the fixing mechanism to transition from a static screw connection to a dynamic, tool-free release system. This enables secure fixing during operation while allowing easy replacement by simply moving the resilient member to the second position.
Solution Approach 2:
The invention extracts the fastening function from the light source device itself and places it on the resilient member that is part of the holder structure. The resilient member includes an engaging portion that can be moved independently to release or secure the light source device, separating the fixing mechanism from the device being fixed.
2Ease of operation
If a resilient member is used to bias the light source device toward the holder, then easy replacement is achieved, but thermal stress may affect the engaging portions
Solution Approach 1:
The resilient member acts as an intermediary between the holder and the light source device, providing a compliant fixing mechanism that can accommodate thermal expansion and contraction. By using an elastic material, the system absorbs thermal stress through deformation of the resilient member rather than transmitting stress to the engaging portions on the light source device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and efficient replacement of light source devices by releasing the biasing force during removal and re-engaging it during installation, reducing the complexity of the replacement process and minimizing thermal stress on the engaging portions, thus extending their lifespan.

AI summary
A projector includes a light source device, a holder that accommodates the light source device, and a resilient member formed by bending a bar-shaped metal component is provided. The holder has a receiving portion configured to pivotally support the resilient member in such a manner that the resilient member can rotate toward the inside and outside of the holder, and an engaging portion configured to engage with the resilient member to regulate the rotation of the resilient member toward the outside of the holder. The resilient member engages with the engaging portion under the condition in which the light source device is accommodated in the holder to bias the light source device toward the holder.
