Office Chair Construction Lesson Plan

The following is a lesson plan for constructing office chairs tailored to different teaching scenarios:

Lesson Plan for Building Chairs with Blocks for Young Children in Small Classes

Teaching Content: Focusing on the "function and structure of chairs," guide young children to perceive the functions of the seat, backrest, and supporting legs by observing real chairs, and use low-structural materials such as blocks, cardboard boxes, and bottles to build chair models. Core Competency Goals: Cultivate engineering thinking and spatial cognition abilities, develop hands-on operation and problem-solving skills, and enhance social interaction qualities. Teaching Preparations: Real chairs, blocks, cardboard boxes, bottles, and other materials. Teaching Process:

1. Situational Introduction: Through the "Chair Exploration" activity, guide young children to touch and discuss the functions of each part of the chair, such as the seat supporting the body, the backrest providing support, and the legs supporting the whole.
2. Group Cooperation for Building: Provide materials, suggest that "the legs should be thick to be stable," and encourage young children to try combinations. When encountering structural wobbling issues, guide the group to discuss solutions, such as increasing the number of supporting legs or adjusting the position of materials.
3. Exhibition and Sharing of Works: Organize a "Chair Exhibition" where young children share their works and explain their design ideas, and the teacher summarizes the relationship between structural stability and functional suitability.

Lesson Plan for Building Chairs with LEGO Blocks

Teaching Objectives: Master the basic structure and usage methods of LEGO blocks, learn to build chair models, and cultivate hands-on ability and creativity. Teaching Preparations: LEGO block sets, chair model blueprints, a podium, and a projector. Teaching Process:

1. Basic Introduction: The teacher displays LEGO block works, explains the basic structure (such as studs and holes) and usage methods, and stimulates interest.
2. Explanation of Structure: Combined with the blueprints, decompose the base, backrest, armrests, and other parts of the chair model, and explain the assembly sequence and connection techniques.
3. On-site Demonstration: The teacher gradually demonstrates the building process, emphasizing key steps (such as reinforcing the base and the inclination angle of the backrest).
4. Student Practice: Students independently build according to the blueprints, and the teacher provides guidance during rounds, solving issues such as loose connections or tilted structures.
5. Exhibition and Communication: Students display their works, evaluate each other's design highlights and areas for improvement, and the teacher summarizes the modular thinking of LEGO building.

Lesson Plan Guided by Ergonomic Design (Suitable for Senior Grades or Professional Courses)

Teaching Content: Based on "Office Space Design and Ergonomics," analyze the structure of office chairs (backrest, seat cushion, armrests, five-star base) and the principles of human body adaptation (lumbar support curve, seat height/depth standards, tilt mechanical balance). Core Competency Goals: Establish the concept of "human-object-environment" adaptation, cultivate structured thinking and data application abilities, and foster a people-oriented design philosophy. Teaching Preparations: Disassembled models of office chairs, spinal curvature demonstration boards, 3D modeling software (SketchUp), and an online collaboration platform (Tencent Docs). Teaching Process:

1. Pain Point Analysis: Students share issues encountered in daily use of office chairs (such as a hollow waist or unsuitable seat depth) and measure the parameters of commonly used seats.
2. Explanation of Principles: Combined with models and demonstration boards, explain ergonomic standards (such as the seat height should match the length of the lower legs).
3. Design Practice: Use SketchUp to simulate parameter adjustments, and collaborate in groups to design chair solutions suitable for different scenarios (office, meeting, gaming).
4. Virtual Experience: Construct multiple scenarios using Unity tools to test the comfort and functionality of the design solutions and optimize and adjust the details.
